The remaining filtercake in a wellbore can have a severe impact on the flow capacity of a sand control screen or gravel pack and screen. Constien & Associates offers drill-in fluid and wellbore clean-up treatment selection and evaluation.
Constien & Associates offers 2 types of sand retention testing using brine flow.
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.
Sand Retention Testing designed to meet a variety of conditions.
The C&A Constant Drawdown Test enables the client to quantify critical performance properties of commercial sand control screens including the amount and size of formation sand produced through the screen and loss of screen permeability.
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.
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.
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.
