Mud Logging Services
Geoservices is the industry leader in mud logging, focusing on drilling
support and formation evaluation. Services that provide decision-ready
information about well status and drilling performance are helping
to drill better wells more efficiently. Critical decisions are being guided
by timely and more accurate information on reservoir fluid composition,
lithology to detect pay zones, well placement, and revealing reservoir
connectivity and compartmentalization.
Drilling Monitoring
Mud and drilling data acquired from multiple surface sensors can be
presented versus both time and depth.
Formation Monitoring
Formation characteristics obtained by analyzing rock cuttings and mud
hydrocarbon content are displayed on monitors and recorded on mud
logs.
Drilling Operations Support & Analysis Service
Thema service helps you extract maximum value from the data obtained
through mud logging and real-time surface monitoring of drilling
mechanics and dynamics, hole-cleaning efficiency, fluid influx and loss,
and a range of geological data.
Drilling Monitoring
Mechanical, hydraulic, and engineering drilling data is continually
measured to balance formation fluid pressures, optimize the drilling
process, and maintain a safe operating environment.
Data acquisition
Specialized sensors, located on the rig floor, measure parameters such
as drilling speed, drillstring rotation, and weight in the mud pit room.
From these measurements mud pit volumes, mud flow rate, and mud
weight in the shale shaker area can be discerned as well as parameters
such as mud gas level, return flow rate, and return mud weight.
Additional sensors may be placed on the cement unit and in the flowline,
choke, and kill line.
Data processing and display
The surface acquisition system processes signals from the sensors; data
can be displayed versus both time and depth at any location on the rig
or sent to remote displays via the Web. The data is also presented
through mud logs and drilling logs, which are produced in customized
formats and scales daily or on request, providing a record of drilling
activity.

Formation Monitoring
Cuttings description
Detailed analysis of of rock cuttings samples taken from the shale
shakers to determine their composition, physical attributes, hydrocarbon
content, and matrix porosity.
Samples of rock cuttings taken from the shale shakers are prepared for
analysis in the mud logging unit. Trained mud loggers examine the
cuttings using a fluoroscope, binocular microscope, and laboratory tests
to determine their composition, physical attributes, hydrocarbon
content, and matrix porosity. Use of industry standard protocol ensures
consistent reporting. The information is used to update computerized
mud logs at the depth from which the sample originates.
Gas chromatography
Onsite extraction and analysis of gas from the drilling fluid to determine
the C1–C5 composition for gas ratio analysis. Technologies are available
to counteract cold mud returns and the contaminating effects of modern
drilling fluid components.
Gas traps located at the shale shakers liberate gas from the drilling fluid.
The gas is transported under vacuum via a pipe to a gas chromatograph
in the mud logging unit. Flame ionization detectors (FIDs) with a fast
cycle time determine the C1–C5 composition. The acquisition system
records the results in the database at the depth corresponding to the
origin of the gas and displays them on the rig monitors and mud logs.

LithologyPlus Quantitative Cuttings Analysis & Imaging Service
Early availability of detailed analysis improves
decision-making
LithologyPlus service enables quantitative mineralogical analysis of
cuttings as they return to surface, using a high-resolution digital
microscope and X-ray diffraction—techniques that were previously
accessible only in the laboratory.
Early availability of reliable and reproducible measurements allows fast,
accurate identification of the lithology and formations being drilled,
enabling
monitoring and optimization of well trajectory
comparisons between wells
selection of the best zones for logging, sampling, and completion
verification of downhole mineralogy measurements.
Hostile downhole conditions do not adversely impact this surface data
acquisition. The portable equipment is easily transported to the wellsite
and can be operated by a standard Geoservices mud logging crew.
High-resolution digital microscope (HRDM) images enhance
cuttings description
High-quality, magnified digital images of cuttings samples are generated
at the wellsite and displayed on a 17-in color LCD monitor as well as
reproduced on the log. The images exhibit significantly enhanced color
resolution, illumination, and depth of field compared with conventional
techniques. Grain and pore sizes can be measured to within tens of
microns because of superior image processing and magnifications
ranging from ×20 to ×200.
X-ray diffraction (XRD) enables cuttings mineralogy analysis
Each mineral creates a unique, characteristic X-ray diffraction pattern.
The magnitude of the signal is proportional to the amount of the mineral,
enabling a quantitative analysis of cuttings mineralogy. Quartz,
anhydrite, calcite, dolomite, siderite, clays, and feldspars can all be
measured.
Data storage and transmission increase accessibility
Images and data are recorded and archived for later retrieval and well
comparisons. They can also be transmitted to remotely located experts
in real time, reducing the number of personnel required at the wellsite.
Thema Drilling Operations Support & Analysis Service
Maximum value from mud logging and other surface measurements
Thema drilling operations support service monitors and analyzes fluid
influx and loss in the wellbore, drilling mechanics and dynamics, hole-
cleaning efficiency, and a range of geological data. It also offers superior
detection of the C1–C5components in gas extracted from the drilling mud
for gas ratio analysis.
Superior data quality and speed
Signals are converted from analog to digital as close to the sensors as
possible, eliminating analog signal transmission and the need for
multiple cables running across the rig floor. High-frequency acquisition,
improved data resolution, and increased storage and computation
capacity enable faster processing of complex data.
Real-time monitoring and analysis
Thema service analyzes real-time data streams from a number of
sensors and displays decision-ready information on drilling performance
and safety via customizable screens. A summary of the real-time status
of the well is obtained by combining depth- and time-based data related
to
Wellbore pressure balance
Fast, reliable detection of fluid influx or loss in the wellbore, even at very
low volumes, gives a valuable edge during drilling operations. The
system reduces the number of “false alarms”, which require time-
consuming flow checks. Early kick detection is further supported by
pumpoff gas analysis to identify potential underbalance situations.
Automatic flowback fingerprint is captured and displayed on screens
when the rig pumps are stopped, for quick and easy visual reference.
Drilling mechanics
The wear and behavior of the drill bit are assessed by monitoring key
drilling parameters—axial (bit bouncing) and torsional (stick/slip)
vibration frequencies and energy—through measurements made by
surface sensors. Potential issues like bit balling, drillstring vibration, and
bit wear can be anticipated and drilling parameters can be optimized to
improve ROP and increase equipment life.
Hole condition
Wellbore stability and hole-cleaning efficiency are analyzed in real time
by comparing measurements of relevant parameters—such as pickup,
slack-off, and free-rotating weights; torque; and equivalent circulating
density (ECD)—with theoretical values calculated using industry-
standard models. Hole-condition monitoring can be further enhanced
through the use of cuttings flowmeters.
Expert support
Thema service includes engineers both on the rig and in your office,
working together to ensure that the right information is delivered within
your organization in a timely manner. They are supported by remotely
based engineers and geoscientists with global experience in optimizing
drilling operations.

M-I SWACO offers a complete line of solids control technologies that
improve drilling rates and reduce costs through the efficient removal of
drilled solids.
Drilling Waste Management
Engineered cost-effective technologies offering a wide range of cuttings
treatment systems designed to reduce the HSE footprint of drilling

Solids Control Systems and Products
Solids control equipment and services that remove solids to maintain
drilling fluid integrity
M-I SWACO offers a complete line of solids control technologies,
comprising shakers, screens, centrifuges, D-SANDERS, mud cleaners and
fluid processing systems. Our integrated portfolio of cutting-edge solids
control technologies are engineered to optimize drilling efficiencies by

We design and operate solids control solutions that improve drilling rates
and reduce costs through the efficient removal of drilled solids. As
importantly, our new generation solids control solutions minimize
considerably the environmental footprint of your operation.
In developing our portfolio of solids control technologies, we went far
beyond a one size fits all approach. We recognized that each project and
each rig is different, and that diversity extends to the solids control. Our
Rig Engineering and Systems group works closely with rig designers,
contractors, operators and shipyards to assess their unique
specifications. We examine well programs to determine the optimum
solids control program to meet specific cost, operational and
environment requirements.
The result is an integrated drilling and waste management configuration

Shale Shakers
Specially designed high-capacity units for all drilling environments M-I
SWACO designs, manufactures and operates a complete line of
advanced balanced-elliptical and linear-motion shakers for all onshore
and offshore applications. Whether used as scalping, primary or stand-
alone units, our high-capacity shale shakers deliver unmatched solids
removal. All of our shakers are available for sell or rental.
We pioneered the design of shakers that occupy minimal rig space, but
deliver the muscle to handle high solids volume. In high ROP
applications, our shakers keep solids at bay, allowing your active drilling
fluid to perform at peak efficiency.
In designing our suite of high performing shakers, we looked first at what
they would be asked to do. Since drill solids degrade rapidly when first
processed, it is critical they quickly be removed from the circulating
mud. That's where the shaker comes in, playing a vital role as the first
mechanism for solids removal. Failure to keep solids out of the active
mud could mean diminished ROP, equipment damage, non-productive
time and higher costs. In designing our shale shaker technologies we
considered:
The shaker vibration pattern
Vibration dynamics, or G-force
Deck size and configuration
Shaker processing efficiency
Shaker screen characteristics
What resulted are some of the most innovative, high performing and
cost-effective shakers on the market.

Centrifuges
Decanting units that deliver the highest level of environmental
performance
M-I SWACO provides high-speed, variable-speed, and fully variable-
speed centrifuges designed specifically to process drilling fluids to the
highest environmental standards. Our decanting centrifuges are
designed to deliver high fluid recovery rates and efficient solids control.
Together, that adds up to a significant reduction in the operator’s total
fluids cost and less waste for disposal.
The M-I SWACO line of ruggedly built centrifuges were designed for both
oilfield and industrial applications. They are especially effective in
meeting the fluid-on-cuttings discharge requirements in environmentally
sensitive areas.
Our centrifuges recover as much as 95 percent of the barite in weighted
drilling fluids. The barite is returned to the active mud system, while the
decanting centrifuge discards the finer, lower-gravity solids.
In chemically enhanced dewatering systems, M-I SWACO centrifuges
reduce liquid discharge volumes significant while enhancing total solids
control system efficiency.

Mobile, high-efficiency solids control for land operations
The M-I SWACO OptM-Izer solids control technology is a mobile closed-
loop unit engineered to time, labor and installation costs. The OptM-Izer
can work standalone or as a supplement to rig shakers. It can move in,
rig up and be operating on location within two hours of arrival.
The OptM-Izer operates in three processing modes, depending on the
specific application and requirements:
High-volume. Drilling fluid is drawn from the rig via the 6-in. suction
line and into two fully variable-speed-centrifugal feed pumps inside the
pump room. They, in turn, move the fluid to the two fully-variable-speed
centrifuges. The centrifuges are mounted atop the pump room so that
the solids can discard into the catch-tank portion of the trailer while the
liquid effluent returns to the tanks mounted below, inside the pump
room. The effluent then returns to the rig via a separate fully-variable-
speed centrifugal pump at the same rate as the fluid entering the tanks
Dewatering. This mode is similar to high volume processing, but with
an additional chemical-injection line tapped into both centrifuge feed
pumps. Drilling fluids are flocculated on the fly while flowing toward the
centrifuge-feed piping. Clear-water effluent is piped directly into the
effluent tank for immediate, metered return to the rig via the
automation package and level controls. The flocculated solids are
discarded directly into the trailer’s catch tank.
Barite-recovery. Operators can switch the centrifugal feed pumps from
parallel to series operation. In the series mode, the No. 1 centrifuge
processes mud in low speed operation and the effluent returns to the
polishing tank. There, it is polished through the No. 2 centrifuge. The
barite recovered from the first centrifuge passes directly into the slurry
tank mounted in the pump room, along with the polished effluent from
the No. 2 centrifuge.
Applications
OptM-Izer was engineered for land rigs not equipped to perform
specialized solids-control operations and do not require these
capabilities while drilling the entire well.
OptM-Izer provides those operations barite recovery, high-capacity
processing, dewatering and/or mud stripping.
Benefits
Better solids removal to reduce dilution and waste volumes
Fully-variable speed- centrifuge technology lowers the percentage of
liquid on cuttings, while the entire OptM-Izer package is fully contained
to avoid any liquid/solid spills
Increased solids removal efficiency
Lower mobilization, transportation and installation costs
Reduced manpower requirements
No crane picks
Lower drilling-waste disposal costs.
FLUID PROCESSING SYSTEM
Integrated and high-efficiency solids-control, mud mixing solution M-I
SWACO provides a uniquely engineered FLUIDS PROCESSING SYSTEM
(FPS) as a fully integrated and complete solids-control solution. The FPS
combines all solids control technologies from shakers to centrifuges to
D-GASSER units in a single skid-mounted unit. Unlike systems that rely
on equipment from others, the FPS offers a suite of field-proven
technologies functioning as a single unit.
Complementing the FPS is M-I SWACO Mud Mixing technologies that are
customized for the parameters and drilling objectives of the specific well.
Regardless the rig size or project complexity, we will engineer, fabricate
and commission a mud-mixing system matched specifically to your
operation. We offer either a single educator unit or a fully automated
mud mixing network for both drilling and completion fluids.
Pressure & Fluid Management System
Automatic pressure control and effective removal of drill solids and gas
from drilling and completion fluids
RHE-USE Fluid Processing System
The RHE-USE process is a patent-pending technology that allows
operators to reuse invert emulsion drilling fluids over multiple wells
without relying on reclamation through high rates of dilution. The
process treats oil-base drilling fluid, reducing solids below 1% while
drilling.
Mud Mixing
Regardless of rig size or project complexity, M-I SWACO will use our
operational and engineering experience to design a system that meets
the customers and market expectations. We will then engineer, fabricate
and commission the mud-mixing system required to perform efficiently
and safely.
Whether it’s a single HIRIDE eductor, or a fully automated, touch screen-
controlled, multifunction system, it will deliver the best performance
available.
If one quality best describes the system, it is “versatility.” Originally
conceived for mixing drilling fluids, an M-I SWACO system can be
designed for completion fluids as well. Rugged construction, using low-
temperature carbon steel and stainless steel, ensures long life in hostile
environments. All components feature a minimized footprint and the
flexibility to be positioned as rig space dictates.
All of our Mud Mixing technologies are constructed of rugged, low-
temperature carbon and stainless steel. As a result, they perform
efficiently, safely and over a longer life, regardless of the environment.
What’s more, we have engineered into the systems components
designed specially to protect the health and safety of workers.

System for improving efficiencies, safety in HTHP wells
The M-I SWACO Mud Temperature Control System improves safety and
drilling efficiency in HTHP applications. The technology reduces fluid loss
and non-productive time (NPT) while also protecting the health and
safety of the rig crew.
In HTHP wells, even the most temperature-tolerant drilling fluids have
their limits. At a certain point, these muds begin to break down or
behave erratically, resulting in fluid loss, reduced viscosity, stuck pipe,
unstable filter cakes and other problems.
In addition, overheated oil-based muds can release fumes that result in
uncomfortable and hazardous breathing conditions for rig crews.
Further, fluids heated beyond their limits can produce inaccurate
readings from Measurement While Drilling (MWD) and Logging While
Drilling (LWD) tools. They also can lead to excess wear on the
elastomers of the MWD, LWD tools, as well as those in BOP) riser,
shakers, centrifuges and mud pumps.
The DRILLING FLUID TEMPERATURE CONTROL system is engineered with
a specific focus on efficient heat transfer in drilling fluids. The system
has been field-proven to reduce risk factors and drilling complications
while simultaneously increasing safety and decreasing operating costs.
From installation through everyday maintenance, every feature of the
system has been developed with HTHP operations in mind. The system is
built around the well-proven
ALFA LAVAL titanium plate heat exchanger and is designed in
accordance with ASME or PED codes and standards.
Features

Vacuums offer simple installation, high-performance efficiency and total
containment for the utmost in HSE effectiveness. They also are easy to
operate and maintain and deliver a relatively small system footprint.
The CLEANCUT pneumatic system minimizes the need for crane lifts and
allows cuttings to be transferred at great distances. CLEANCUT also can
accommodate significant variances in the liquid content of the feed
materials. For these reasons it has evolved into the preferred method for
the bulk transfer of cuttings.

All-inclusive planning, execution and monitoring CRI process
M-I SWACO has developed an integrated Cuttings Re-Injection (CRI)
process that has emerged as a proven and effective solution for the
disposal of drilled cuttings. By eliminating the need to accumulate, store
and haul cuttings to shore for treatment, operators save time, labor and
rig space. Some of the key factors in gaining these benefits are effective
handling and preparation of cuttings before re-injection.
Our integrated and site-specific CRI systems uses slurrification as a
practical and cost-effective way to process drilled cuttings for re-
injection. Cuttings are collected, conditioned and mixed with seawater to
form viscous slurry ready for immediate re-injection into a downhole
formation.
M-I SWACO also designed an all-inclusive CRI assurance program to
minimize the risks of future liability. A multi-disciplinary team of
scientists and engineer start by examining the merits of potential
injection formations. The team then designs and executes the injection
process, all the while monitoring the progress. That monitoring
continues after the project is complete.
The comprehensive CRI process gives operators the confidence and
ability to:
Re-inject into existing production wells
Drill and re-inject simultaneously
Inject into existing wells or into dedicated cuttings disposal wells
High-speed centrifuge for maximum in liquid/solid separation
The VERTI-G cuttings dryer incorporates a high-speed vertical centrifuge
that achieves maximum liquid/solid separation in large-volume
processing. This mechanism makes the VERTI-G dryer one of the
industry’s best performing and most dependable cutting dryers. The
VERTI-G dryer gives operators a critical advantage in meeting
increasingly stringent environmental rules for cuttings disposal.
Versatility and high-performance
Drill cuttings are conveyed from the shakers to the VERTI-G cuttings
dryer through a variety of site-engineered conveyance systems that
include
Gravity feed
CLEANCUT pneumatic transfer
Vacuum transfer
Screw conveyors
The flow of cuttings into the VERTI-G dryer is PLC-controlled and
continuously fed to yield optimum liquid/ solids separation. Once
cuttings are introduced into the dryer’s charge hopper, widely spaced,
independently adjustable flights continuously direct cuttings to the
screen surface. Flights are tungsten carbide coated to reduce wear and
ensure optimum tolerance.
Flights within the VERTI-G dryer create a rolling action that promotes
efficient separation and prevents screen plugging. Under high G-forces
created by the large cone diameter, liquid/solids separation occurs
instantly as cuttings make contact with the finer-mesh, high-capacity
centrifuge screen. The end result is clean return fluid and dry solids
discharge.
Improved efficiency means lower costs
The VERTI-G cuttings dryer improves overall cost-efficiency by
recovering costly drilling fluid that is recovered from cuttings, as well as
whole mud lost from shaker failure and rig motion. Further, the VERTI-G
cuttings dryer produces lower waste volumes by generating dryer solids
in both oil- and synthetic-base drilling fluid systems. The reduced waste
volume can in turn dramatically reduce disposal costs.
Ease of maintenance
Routine flushing of the dryer system prevents solids buildup in the
recovery area and minimizes shutdowns for cleaning. In addition, normal
wear parts are easily accessible from the top of the unit; belts are easily
changed without removing gear assembly. Interchangeable tungsten-
carbide rotor blades protect rotor and gearbox from excessive erosion,
minimizing main component failure and lowering maintenance cost.
