Frequently Asked Questions
The focus of practice for C&A is research and testing in:
– Selecting of sand control screens for horizontal and vertical wells in unconsolidated formations.
– Evaluations of drill-in fluids for fluid loss control and filtercake cleanup. Evaluation of fluid loss control pills.
– Rheological measurements of linear and cross-linked hydraulic fracturing fluids, drill-in fluids and well control pills.
– C&A has developed a test apparatus to assist in verifying performance of Friction Reducers in small-scale tubing.
While C & A completes testing for companies all over the world, our lab is located in Owasso, Oklahoma, USA, a suburb of Tulsa.
C&A, Inc. is recognized globally because we focus on applied, problem-driven testing. Our methods are built around real well conditions, not idealized assumptions. Clients rely on C&A because our testing is repeatable, defensible, and directly applicable to completion and sand control decisions. Many of our procedures have been refined over decades of field-driven feedback and are trusted by operators, service companies, and screen manufacturers alike.
Completions testing can directly impact well performance, longevity, and overall project economics. Proper testing helps reduce sand production risk, minimize formation damage, optimize screen and fluid selection, and avoid costly remediation or workovers. By identifying failure modes before execution, testing allows operators to make informed decisions that reduce uncertainty and improve the probability of long-term production success.

Yes. C&A regularly designs and executes custom test programs to match specific reservoir conditions, fluids, screens, and completion strategies. Custom testing is developed in collaboration with the client to ensure the test objectives align with real-world operational decisions. This includes modifying existing procedures or developing new test methodologies when standard tests are not sufficient.
C&A test results are generated using controlled laboratory conditions, calibrated equipment, and repeatable procedures designed to reflect realistic completion environments. Tests are intended to be comparative and decision-supportive, allowing clients to evaluate relative performance between fluids, screens, and completion designs. Pass/fail criteria are established using empirical data developed from actual client wells that C&A has supported over more than two decades of completion projects, ensuring test outcomes are grounded in real-world.
Test data is provided directly to the client in formal reports and supporting files. Data is treated as confidential and is not shared publicly. If ongoing or repeat testing is performed, historical data can be referenced and compared to new results upon request.
Each project begins with a technical discussion to define objectives, operating conditions, and success criteria. C&A reviews formation data, fluid systems, screen designs, and any relevant field constraints before testing begins. This upfront alignment ensures the test program is efficient, relevant, and produces actionable results.
Samples are typically shipped directly to the C&A laboratory in Owasso, Oklahoma. Packaging and handling requirements are coordinated in advance to ensure sample integrity and traceability. Upon receipt, samples are logged, documented, and stored appropriately until testing begins.
