OUR SERVICES

SAND CONTROL

C&A has successfully delivered testing and consulting services in the oil industry since 1997. C&A provides customized lab testing for Oilfield Completion and Stimulation Services. Test offerings are based on client protocol, data requirements, and specific well conditions. Our tests yield precise, high quality, reproducible data - on time, every time.

The C&A Constant Rate Brine Flow Test is a constant rate test typically using 3% KCl which simulates an erosional-type failure of the formation onto the screen. The C&A Cyclical Brine Flow Test a constant drawdown test designed specifically for injector wells.

SHALE FRACTURING

C&A offers shale strength testing to help determine damage in strength to cores from fracturing fluids.

C&A offers Capillary Suction Testing (CST) which utilizes off-the-shelf equipment to give rapid determination of fluid and shale interactions.

C&A has developed a small scale laboratory pipe flow device to compare the performance of different friction reducers in water, making it possible to perform friction testing with actual field water samples.

A suite of practical laboratory tests has been developed to characterize the performance of shale fracturing fluids and chemicals.

FRACTURING FLUIDS

High pressure testing is available to measure rheological properties of fluids at up to 30,000psi and 600oF. Testing is completely customizable to match specific conditions including shear rate, pressure, and temperature.

CONDUCTIVITY

C&A offers testing for measuring the long-term conductivity of ceramic, natural sand or resin-coated proppants. Testing procedures for fracture conductivity can be performed per standard ISO 13503-5 recommendations.
