1.2.2 Memory Production Logging (MPL) Adaptor / CCL

The MPL adaptor counts the pulses from each sensor in the tool string then sorts, compresses and records thedata. Unlike the telemetry tool (which transmits all the data to an acquisition system) the MPL adaptor storesall data within its own 64 MB memory bank.

The adaptor contains its own casing collar locator (CCL). The CCL incorporates two permanent magnets anda coil and is used for detecting casing and tubing collars for depth correlation purposes.

1.2.3 Gamma ray

The gamma Ray tool employs a sensitive sodium iodide scintillation crystal and photo multiplier tube todetect naturally occurring and artificially induced gamma ray radiation in the formation. Most of the gammaray radiation penetrates the casing and tubing. Therefore, the tool can be used throughout the life of the wellfor correlation to the surrounding litho logy.

1.2.4 Gradiomanometer

The gradiomanometer uses a transducer to measure the differential pressure over a 24-inch column of fluid.The pressure enters the tool via two ports spaced 24 inches apart and a differential pressure measurement istaken. Since the column height and gravity are constants, the average fluid density of the column is easilycalculated and presented. Due to the fast and sensitive response, this measurement can be obtained whilecontinuously moving in the wellbore. Pressure transducers are available in the 2 or 5 psi range.

Note: The transducers in the gradiomanometer are extremely sensitive; handle the tool carefully to prevent transducerfailure. Apply pressure to the transducer (tool) extremely slowly to avoid over ranging of the diaphragm. This appliesto depressurizing of tool as well (i.e. pressurizing / depressurizing of lubricator).

1.2.5 Dielectric

The dielectric tool measures the capacitance of the fluid that passes between the probe and the body of thetool. This measurement is used to help locate first water entry and is commonly referred to as fluidcapacitance, water hold-up or water cut.

1.2.6 XY Caliper

The XY caliper consists of two independently cross-hole diameter measurements made at right angles (90)and performed by two spring loaded, non-motorized measurement arms. The tool can be used for open holeor cased hole operations in surface read-out or memory mode and should be run utilizing a roller or bowspring centralizer. Measurement range is 2" - 24".

1.2.7 Pressure / Temperature / Flow Meter (PTF) orHigh Resolution PTF

The pressure/temperature/flow tool incorporates a quartz pressure sensor, temperature sensor and bi-directional flow sensor.

The quartz pressure sensor has a built-in temperature compensation sensor and is isolated from the wellborefluids by a bellows and buffer of silicone oil. The temperature sensor is a temperature sensitive platinumresistor housed in a thin inconel probe. The flow sensor contains the electronics for sensing rotationaldirection and speed with the use of a hall effect sensor.

1.2.8 Fullbore Spinner

The fullbore spinner has a collapsible impeller that is designed to be lowered through tubing to open into alarger diameter casing or bare-foot completion giving a velocity measurement covering a much larger cross-sectional area. The increased accuracy and sensitivity of a fullbore spinner results in a true downhole flow

measurement.

1.2.9 Continuous Spinner

The continuous spinner uses an impeller which is integrated into the tool body. This configuration iseffective in restricted boreholes, tubing and in areas of very high flow velocity.

1.2.10 Roller Centralizer

The roller centralizer is used to centralize the tool string while running in and out of the. Rollers on thecontact points prevent the tool string movement from wearing the arms as they expand and contract to fit the

wellbore. Use of centralizers is encouraged in deviated wellbore conditions to ensure the accuratemeasurements of flow velocities and callipered sections are obtained.

1.2.11 Bow Spring Centralizer

The bow spring centralizer can be positioned anywhere in the tool string (most commonly above the batterypack housing and directly above of the PTF) and is used to keep the string centralized while running in andout of the hole. The centralized arms expand or contract to fit the inner diameter of the wellbore. Unlikeroller centralizers, bow spring centralizers are commonly used in bare-foot completions.

1.2.12 LineWise Interface Box

Data is sent to the LineWise interface box by voltage (-/+5V) or frequency. Data sent to the interface box canbe from any of the following during a memory production log: depth, line speed, tension and pressure.

All data acquired by the LineWise interface box is recorded and saved to file for future reference.

1.2.13 MAT USB Interface Box

The MAT USB interface box is used in conjunction with a USB cable to connect the LineWise/logging

computer to the MPL adaptor for upload and download of information. Also located on the MAT USBinterface box is an 18-volt connection port to power the tool string at surface. This is used for pre-job toolcalibration verification.

This piece of hardware requires appropriate drivers for operation. These will be supplied with the unit andshould be copied to the following folder: C:\Program Files\LineWise\Drivers.

2 Programming the MPL for Logging Requirements

2.1 Hardware Connection

The first step to programming the MPL adaptor is the hardware connection from the MAT job computer tothe MPL adaptor. This is accomplished with the use of a USB cable and MAT USB Interface box supplied byLee Specialties Ltd. See picture below for hardware configuration.

Note: Plug the USB cable into the USB Interface Box quickly. If this is done correctly the green L.E.D. on the box willlight up continually and the red L.E.D. will flash only once. If the red L.E.D. flashes continually, disconnect the USBcable and try again to obtain communication with the tool. A tool connection error status box will be displayed ifcommunication is attempted without proper USB cable connection.

2.2 Software Configuration

Once the hardware connection has been established, programming of the software can be started. Click onthe MAT Job software icon and click File and New.

2.2.1 Setting up the Program Table (Time Schedule)

Double click the blank space directly below the date column on the Program Table, this will automaticallydisplay the current date and time. The Powercolumn will default to On with the Rate defaulting to Typical.Any of the columns can be adjusted by a single click directly on the cell in question. Once the correct dateand time has been selected. The power option (On/Off) can be adjusted for the specific date and time.Multiple schedules can be added by simply double clicking on the blank row below the last entry.

The program table also allows for three different rates to be selected from. The rates are either Low, Typical,orMax.

Low: 1 sample per second Typical: 12.5 samples per second

Max: 25 samples per second.

For example, the illustration located in sub-section 1.1 shows the following schedule: At 16:34:02 on 2003 / 3/ 24 the tool is scheduled to power on at a sample rate of 25 samples per second (Max setting). The tool is setto continue sampling at this rate until 17:45:02 on 2003 / 3 / 24 at which time the sample rate changes to 12.5samples per second (Typical setting) until the battery voltage drops or the battery pack is removed.

Note: Ensure the sample rate does not change during a pass as this will affect the data quality.

If idle time in the hole is anticipated, simply schedule the tool to power off for this time to optimize batterylife and available memory.

2.2.2 Uploading Information to the MPL Adaptor

Once the Program Table has been completed, upload of settings and schedules can be continued. Click on Fileand scroll down to Program. Once program has been selected, the upload of information from the computerto the MPL adaptor will begin. This operation will complete three different objectives:

First, the connection will synchronize the internal tool clock with the computer clock. This is essential forDepth/Time management when merging the time with correlating depth. Below is the status box that shouldappear while this operation is being complete. Click Done when this task has been completed.

Second, it will transfer the Program Schedule from theMAT Job software to the tool.

Third, it will erase the data currently on the MPL adaptor to ensure optimal data storage space. Below is thestatus box that will appear while the tool memory is being erased.

Once the tool erase has been completed, a notification will appear stating the tool has been successfullyprogrammed and verified.

2.3 Powering the MPL Adaptor

Once the configuration of the software has been completed and the data has been uploaded to the MPL

Adaptor disconnect the MAT USB interface box from the MPL adaptor and remove the USB cable from thecomputer.

2.3.1 Battery & MPL Adaptor / CCL Connection

The battery housing is simply threaded to the top of the MPL adaptor. This must be done within 15 minutesof the MPL adaptor being disconnected from the computer or the data that was uploaded may be lost.

2.3.2 L.E.D. Display / Location

Once the battery housing/pack has been attached to the MPL adaptor the light emitting diode (L.E.D.)located within the top of the housing will flash for approximately 30 seconds. If this does not happen theremay be a faulty connection between the battery pack and MPL adaptor, a low voltage on the battery pack,

hardware failure, or a memory error. The following list shows the L.E.D. codes:

L.E.D. flashing for 30 seconds: Tool is operating properly.o Flashing fast: Max rate (25 samples per second).o Flashing slowly: Normal rate (12.5 samples per second).

L.E.D. does not light up: Poor battery connection to Adaptor or major hardware failure. L.E.D. lights up continually (not flashing) for 30 seconds: Internal clock has lost time reference. L.E.D. lights up continually for five seconds: Memory error.

After right clicking on the empty cell, select New. Thecell will now be filled with the word Unknown. Click the cell again and select the tool required from the pulldown menu.

Note: Tools must be selected in the same order as they will appear in the string - top to bottom.

3.2 Filename & Serial Number

Once the correct sonde has been selected, the appropriate filename and serial number must be selected toensure that correct calibration is applied.

Continue adding sondes with appropriate filenames and serial numbers until the complete logging string ispresent in the Sonde table. Repeating the above procedure in the blank row located directly below the lastsonde entry does this. Make sure the order is correct and reflects the tool string configuration.

4.1 Pre-Job Calibration Verification

Note: Before beginning a memory production log it is always a good idea to ensure the tool is functioning correctly andto verify tool calibrations before it is run in the hole.

After the complete tool string has been connected and before the battery pack has been attached, power thetool string with the use of the 18-volt connection port on the MAT USB interface box - this can be done with a110-volt adaptor or the battery adaptor cable. At the same time connect the USB cable to the loggingcomputer and the 15-pin connector to the MPL adaptor. At the conclusion of this step, the tool string shouldbe powered and communication between the computer and MPL will be established.

Verification of the calibration and overall function of the string can then be viewed by either raw or calibrateddata. This can be achieved by clicking on Tool on the task bar and scrolling down to Acquisition. Once

Acquisition is highlighted, scrolling to the right will allow the option of Raw (frequency output, seeillustration below) or Calibrated (applied calibration output).

Note: in order to view the calibrated data, the correct sondes needed to be selected along with the appropriate serialnumber for calibration reference (see section 3).
