PVT Lab.

Equipped with latest techniques of PVT analyses services are used to provide high-quality information for reservoir fluids to assist development and exploration operations to improve recovery.

PVT Laboratory is equipped with state-of-the-art equipment and latest measurement and interpretation techniques. The highly automated mercury free PVT laboratories don’t keep any area for mistakes and delays and it’s now a real addition to PLRS’s range of integrated services.

The output data is filtered through consecutive stages of validation and Q.C. and the final submission is specially designed to fit with companies’ requirements for more accessibility and compatibility with reservoir description software packages.

Reservoir Characterization Labs.

Since 2002, PLRS has been providing core analysis services for the local industry, building up a reputation for quality, reliability and excellence of core analysis services whereby it’s crucial for E&P industry.

At PLRS a full range of services are available and some of the services crosschecked with allied laboratories to assure the premium quality of results. PLRS also established core storage facilities with the latest technologies of handling enabling to handle large amounts of core Samples and provide rapid turn-around times for our customers In addition to our conventional core analysis services, PLRS provides a broad range of Special Core Analysis tests.

Our dedicated team of qualified staff is committed to quality, reliability and client focus.
Close liaison with the international Reservoir Characterization groups enables us to maximize the value of core-derived data by offering integrated solutions in Reservoir Characterization, Formation Damage and Reservoir Performance.
