New LWD Service Integrates Formation Fluid Analysis and Sampling

The fluid analysis and sampling service can capture up to 16 fluid samples.

Determining the fluid properties of a reservoir by using pressure/volume/temperature (PVT) analysis is essential to petroleum reservoir studies, production equipment design, and reservoir recovery efficiency estimation. The properties of the formation fluid are used to determine reserves and to predict reservoir performance and economics. PVT properties such as bubblepoint pressure, gas/oil ratio, viscosity, oil formation volume factor, and detailed composition are important to well performance analysis, material balance calculations, reservoir simulation, and production engineering calculations.

Once the reservoir information is available, the well team makes the critical field development decisions. Conventional post-well wireline formation testing operations can delay decision making for days, sometimes months, depending upon the logistics involved in transporting a sample from the wellsite to a PVT laboratory. Additionally, wireline deployment is expensive in horizontal and highly deviated wells because of the extra time and equipment required to convey the tools to the test intervals.

Integration Benefits

The latest logging-while-drilling (LWD) technology integrates downhole fluid analysis and sampling with formation pressure while drilling (FPWD), thereby providing environmental, economic, time-saving, and data quality benefits over traditional methods of reservoir characterization. The integration enables three distinct services: real-time formation pressure tests, real-time in-situ measurements of fluid properties, and downhole capture and retrieval to the surface of fluid samples.
