VERTICAL VS. HORIZONTAL DRILLING AND COMPLETIONS
NOTE: Throughout the presentation, blue dialog boxes such as this one are added to provide the detail and context that remains unexplained without the verbal presentation
HORIZONTAL VS. VERTICAL DRILLING
4
The primary objective in horizontal vs. vertical drilling is to expose more volume of rock to the wellbore for higher production rates
RESERVOIR CHALLENGES
Unconventional Reservoirs Conventional Reservoirs
Tight, low permeability, low porosity reservoir Higher permeability, and higher porosity reservoir
Brittle shale, tight sand, or fractured carbonate Porous sands, porous carbonates, fractured carbonates
Trapped by lack of horizontal permeability Requires a stratigraphic or structural trap
High total organic carbons (TOCs) in reservoir Low total organic carbons (TOCs) within reservoirSourced from high TOC shales above or below
Mostly drilled with horizontal well through reservoir Drilled with vertical well through reservoir
Challenges to geosteer within the formation Clear definition of field and reservoir limits
Generally fraced (fracked) to stimulate production Generally no need to stimulate production
Rarely any risk of water interrupting productionException is fracing to water reservoir above or below
Often water is the drive mechanism for production
Pressure depletion and gas expansion are primary drive mechanisms
Pressure depletion is also a common drive mechanism
Highly repeatable within close proximity Not easy to repeat within close proximity
Reliance on type curves for Estimated Ultimate Recoverable - EUR
Reliance on pressure or volume for EUR
Often insufficient wells for accurate analysis Often insufficient data for accurate analysis
Greater rock heterogeneity than expected Rock heterogeneity is always expected
Normalization of EUR to constant lateral length
Modeling of EUR range based on multiple variables
Rapid phase changes from oil to volatile oil to gas

It is important to compare all precedent transactions to key developments in the basin and industry including dropping natural gas prices, rig counts, and drilling permits
VALUATION CHALLENGES USING DRILL-OUT OPTION
.
The fundamental assumption with this option is that the operator will attempt to drill all of the possible undrilled wells on term and HBP acreage, with the following concerns, necessities, and limitations
� Identify all potential well locations on undrilled acreage
� Remove all PDP and PUD locations
� How much of the acreage is clustered into sufficient density to create drilling units?
� What percentage of acreage does the operator control within a unit?
� What are the actual or predicted drilling, completion, and lease operating expenses?
� What are the gathering system, processing, compression, and pipeline costs?
� What basis differential at final sales point?
� What is the EUR – Estimated Ultimate Recoverable reserves per well?
� What price deck – NYMEX strip?
� What is the rig availability?
� What permitting time, restrictions (e.g. migratory birds and deer), and limitations exist?
� If the answer to all is positive IRR and NPV then continue, otherwise move to next area
� THE definitive answer to EUR for any resource play is the All Important Type Curve
THE DRILL OUT OPTION
22
.
Definition and Application
� Quantitative and qualitative method of analyzing reservoir and field production
� Performed by using a sample set of wells in a given area or reservoir and evaluating the average historical production to determine the decline curve that best matches that production
� Decline curve then used to project future production on a single well basis through the manipulation of many variables that affect the overall decline of the curve
� Variables include hyperbolic exponent (b-factor), initial production (IP), effective initial decline, and terminal decline
� Estimated ultimate recovery (EUR) can be calculated using these variables
� The wells that factor into a type curve must be cautiously categorized into groups with similar well traits
� Traits include but are not limited to operator, basin, field, reservoir, well status, production date, and drill type
� With a precise EUR calculation, many different economic scenarios can be ran to determine a reasonably accurate value for acreage
THE ALL IMPORTANT TYPE CURVE
Type Curve Projection
Definition and Application
� B factor is a coefficient used in the Arps decline curve equation to model either exponential or hyperbolic decline, depending on the reservoir and production characteristics
� Exponential decline, using the b value of zero is exhibited by a straight line on a semi-log graph, whereas hyperbolic decline with b values ranging from zero to 1 represent a decline that is characterized by an early steep drop followed by flattening, which is typical of tight gas formations including shale
� When modeling shale gas decline, it is not uncommon for reservoir engineers to use b-factors in excess of 1
� The problem with values greater than 1, is that they will approach unreasonable amounts over the entire life of the well
� Therefore, after a substantial b-factor has been applied to the initial decline (1.1-1.4), a terminal exponential decline should be used to realistically project the EUR
THE B-FACTOR
Exponential Decline (b = 0)
EUR = 3.1 Bcf
Hyperbolic Decline (b = .8)
EUR = 4.2 Bcf
Hyperbolic Decline (b = 1)
EUR = 5.9 Bcf
Hyperbolic Decline (b = 1.2)
EUR = 7.4 Bcf
Hyperbolic Decline (b = 1.4)
EUR = 11.6 Bcf

MARCELLUS ACREAGE
25
The following slides demonstrate an example of analyzing a cluster of wells surrounding an undrilled acreage position in southwestern Pennsylvania. The comparison looks at where the wells sit in the basin, and how selectively choosing different wells to generate the type curves yields significantly different results
MARCELLUS ACREAGE W/ THICKNESS
26
The yellow acreage has numerous producing wells around it. The question to be answered is which wells should be included in a type curve and why. The Marcellus thickness map suggests that the southern wells are more similar in thickness to the yellow acreage than the northern wells
MARCELLUS ACREAGE W/ DEPTH
27
The Marcellus depth map is further evidence that the southern wells are more similar to the acreage than the shallower northern wells

FIELD OPERATIONS COST ANALYSIS / OPTIMIZATION
Production operations
require continuous
monitoring during the life
of a field
Optimization is
dependent upon
producing conditions and
pricing environment
PRODUCTION COST OPTIMIZATION
� The valuation of producing assets is based upon the current production rates, EUR, LOEs, downtime, ‘non-recurring costs’, future CAPEX and D&C costs
� The level of production optimization employed by an operator dramatically affects the current valuation, as well as the upside potential to be gained by production optimization
35
Operations need to be optimized to maximize profit and equipment service life
� Facility equipment including pumps, electric motors and gas compressors probably installed early in life of field
� Declining rates and pressures could provide opportunity to reduce costs
� Pumps could be swapped out or modified to fit current application reducing repair costs and downtime
� Electric motors could be properly matched to horsepower requirements, reducing power consumption and cost
� Compressors could be modified or swapped out reducing costs and downtime
� Numerous types of artificial lift equipment may be utilized within a field
� Surfactant Injection (capillary string)
� Plunger Lift
� Progressive cavity pump
� Gas lift
� Rod pump
� Hydraulic pump
� Electrical submersible pump (ESP)
� The more liquid a lift method can handle, the more expensive it is to maintain and operate
36
SURVEYING FIELD OPERATIONS
Increasing liquid volume handling capacity
Many variables affect the efficiency of an artificial lift system. A partial list of variables for a rod pumped well are shown below.
� Pumping unit size
� Stroke length and speed
� Sucker rod size and type
� Downhole pump type and size
� Pump intake pressure
� Gas oil ratio, well head pressure
� Type of fluid produced
� Pump spacing, compression ratio
� Plunger/barrel clearance
Changing conditions during well life cycle necessitate revising equipment design to maximize efficiency
37
ARTIFICIAL LIFT
� A major operating cost driver is well failures
� Controlling equipment failures is critical to optimizing field operations and profitability
� Operating artificial lift equipment outside of design capacities increase equipment failures
� ESP equipment operating below its designed range will prematurely fail
� Over stressed rod pump equipment will lead to premature sucker failures due to buckling and increased tubing wear
� Optimization of operating practices for mitigating scale, corrosion, emulsions, paraffin and H2S will reduce costs and failures
� Example: running a plunger in a gas lifted well may remove paraffin build up more effectively than chemical treating
� Determine the proper balance between maximum production rate operating cost
� Optimization work could have the best rates of return of any project within a company’s portfolio

CONTROLLING DOWNTIME
The following slide demonstrates a Wellbore Utility Chart which is critical to develop for EVERY field to identify exactly what the well has produced from each formation, where it currently is producing, and what future uphole (PBP or PDNP) exists.
The Wellbore Schematic Diagram on the next slide presents a cross-section of the well showing the casing, plugs, tubing, packers, and current state of the wellbore.
If an operator does not have both of these organizational tools and does not constantly update them, then there is a risk of future mechanical problems, lost or forgotten behind pipe pay, and future risks when plugging and abandoning the wells

ORGANIZATION - WELLBORE SCHEMATIC
40
It is necessary for operators to keep a detailed and up-to-date inventory of each individual wellbore schematic. This applies to newly drilled wells as well as older wells that may have been acquired.
The more detailed and available these schematics are, the easier it is to address potential operational issues.
� INEXS provides full analysis of field operations including wellbore utilization evaluation
� INEXS provides direct field operations supervision including accounting
� Pricing based on $/wellbore, $/BOEPD, and shared upside success

FIELD OPERATIONS SUMMARY
FIELD EQUIPMENT AUDIT AND INVENTORY
It is equally important to conduct a complete and thorough inventory of physical equipment in the field, and to complete a detailed written field inventory report so that the producing company can optimize the artificial lift operations, to right size the artificial lift systems, and to monitor and track spills, failed equipment, and potential for future problems
