3 The PMI Advanced Formation Damage & Well Treatment System, Model FDWTS-10K is designed to study formation damage in reservoir condition. The FDWTS-10K is capable to perform proven measurement of : Applications Formation Damage (By mud and Frac fluids, EOR processes) Gas & Liquid Permeability Core Flood Residual Fluid Saturation Relative Permeability, Amott wettability and Core compressibility, etc

4 Procedure Saturate core sample with Formation brine Measure liquid Permeability in reverse direction Flood the Core Sample with Oil (or gas) till Swi Measure effective permeability to oil (or gas) in reverse direction Flow acid across the upstream end face of the core sample to wash the mud cake Flow mud across the upstream end face of the core sample to form a mud cake Flood the core sample with oil (or gas) in reverse direction again to remove all mud filtrates Measure effective permeability to oil (or gas) in reverse direction to obtain the permeability value after the core Flood the core sample with acid in forward direction Flood the core sample with oil (or gas) in reverse direction again to remove acid traces. Measure effective permeability to oil (or gas) in reverse direction to obtain the permeability value after the core acidizing.

5 Instrument The PMI Advanced Formation Damage & Well Treatment System is equipped with a humidifying system that is able to regulate and control the humidity of various gases. The dry gas is split into two streams. One stream will remain dry while the other stream will pass through a humidifier vessel to become humid. The two streams will then pass through flow controllers and join back up in one stream. This stream will have the humidity measured so that the software can control the dry-wet ratio to achieve the desired humidity. The sample cell is designed to hold rock cores with 1" and 1.5" diameters and 1" to 6" lengths. The whole instrument is designed to be corrosion resistant, withstand pressures up to 10000PSI, and temperatures up to 180º C. TESTING CAPABILITIES This system is able to perform the following tests Liquid Permeability & Gas Permeability Fines migration & critical velocity Static Filtration Drilling mud invasion evaluation Formation stimulation

7 Flow in CC/SEC. Flow in CC/SEC. Key Features FLOW RATE S PRESSURE PRESSURE (PSI) Gas Permeability FLOW RATE S PRESSURE PRESSURE (PSI) Liquid Permeability Advanced fully computer controlled system that allows the operation for both automatic and manual modes where can provide precise monitoring and data acquisition Capable of flooding core sample with reservoir fluids at reservoir conditions, including oil, brine, and polymers, etc. Automated temperature control and Automated pressure control Machine made out of corrosion resistant materials Bypass valves for user protection- All controlled systems and components are fail safe The PMI Advanced Formation Damage & Well Treatment System can be used to study formation damage by mud and frac fluids, EOR Processes, General Core absolute and relative permeability testing, wettability etc. The standard configuration allow for liquid/liquid at constant flow rate and liquid /gas at constant pressure rate. The PMI Advanced Formation Damage & Well Treatment System designed is very user friendly both mechanically and in its software interface. This system can be used to study steady or unsteady state relative permeability for liquid/gas at reservoir conditions. Automated humidity control for gases Heating method is provided by oven with digital temperature control. All other valves and other parts such as accumulators are inside. Other parts that do not have to take the heat such as pumps etc. are placed in a cabinet behind the furnace and accessible from behind for service. Simple sample setup and All parts for machine contained within single cabinet Forward and Backward injection capability Downstream wet gas meter for accuracy of gas flow Fraction collector Simple reporting software automatically performs calculations from data Types of Samples: Rock Cores (1inch to 1.5inch diameter, 1" to 6" length) Reported alues: Permeability, Differential pressure over time, Humidity over time Inlet and Outlet pressure over time, Humidity over time, Temperature over time

8 Software The system is controlled through most up-to-date version of Microsoft Windows based software Exporting graphic files to window based word/excel processing files for report generation. Capable to be programmed for automatic repeat measurements or for data acquisition under user selected tolerances. Graphic presentation of the data to be evaluated and analysis results. Provision for off-line data processing. Integrated detailed help system. Calibration routines able to be controlled by PMI s software. PMI Software has built in features for automatic start up and shut down procedures, real time display of the sample analysis progress Machine Configuration Screen PMI Software includes all the data handling features including user defined report generation, data, figures & ability to export to spreadsheets, offline data processing, etc. Auto Test-Step Data Filling Auto Test-Step Sample Chamber Temperature filling Auto Test-Data Recording

9 Unique Features Leak-off core holder A circulating pump to flow mud across the upstream end face of the core sample. One displacement pump connected to an accumulators system via cross connector to flow brine, oil, or acids through the core sample one at a time. Liquids in accumulators are in pressure equilibrium allowing for liquid changes to be conducted under dynamic flow without disturbing the system pressure equilibria. Three brine accumulators to perform clay sensitivity tests. A nitrogen cylinder to flow gas through a gas humidifier into the core sample. Gas seperator and gas flow meter to measure gas permeability in reverse direction. Two weighing scales to measure liquid permeability in reverse direction, and mud filtrates. Two pressure taps to measure the pressure drop along the core sample. SALES & SERICE Our sales team is dedicated to helping our customers find whichmachine is right for their situation.
