Reservoir Stimulation Series Reservoir Stimulation Reservoir Stimulation instruments are designed to provide treatment to reservoir formations or enhance the productivity of a wellbore, using either hydraulic fracturing or matrix treatments. M9115 Electrical Resistivity System Features • • • • • Can perform measurement of rock electrical resistivity. Choice of either fully or partially brine saturated core sample. Resistivity Measurement based on two or four electrode method. Includes core holder and hand pump for desaturation. Burette used for core saturation determination. Specifications Core Diameter: Core Length: 1.5" Up to 4" Resistivity Measurement: 2 and 4 electrodes 10,000 psi Max Pressure: Temperature: Room Condition M9117 Capillary Pressure & Resistivity System Features M9130 Slim Tube System Features • • Determines positive and negative pressure curves. • • • • • • • Uses electrical resistivity index for core sample saturation capacity. Calculates Saturation exponent "n". Calculates Cementation exponent "m". Core holder of Hydrophilic and hydrophobic ceramics used for resistivity measurement. Resisitivity cell used for brine resisitivity measurement. Automated pumping system used for fluid control. Temperature-controlled bath houses entire instrument. Specifications Max Confining pressure: 10,000 psi Max Pore pressure: 10,000 psi Working Temperature: Up to 302°F Capillary Pressure: Core Length: Core Diameter: Power Supply: 145 psi (± 10 bar) Up to 3 in. 1.5 in. (other sizes avail. upon request) 220 VAC Brine Wetted Material: SS-316 (optional Hastelloy) • Determines miscibility at reservoir conditions. Gas is injected at user-controlled pressure through a slim tube, which has been saturated in oil through a high pressure pump. • • • • • Produced gas is measured by wet gas meter. Raw data obtained after testing. High level of automation. Ultrasonic multiphase separator for liquid measurement. Many add on tools extend unit capabilities. Embedded gas injection pump makes safe and easy operation for user. Specifications Tube Length: Tube Diameter: Material: Porous Media: Approx porosity: 80 ft. (24 m.) 1/4 ft. (0.42 m) Stainless Steel 230-310 μm silica 35 % Approx pore volume: 100 cc Working Temperature: 302°F Working Pressure: Fluids: Power: 46 Data sheets and full product specifications can be found on our website.
