Wallingford, CT and Houston, TX – December 7, 2010 – APS Technology, Inc., a leading provider of MWD/LWD (Measurements-While-Drilling / Logging-While-Drilling), drilling performance and vibration management products for the oilfield, announced today that they shipped their 75th WPR propagation resistivity tool in October, 2010. WPR is a compensated-geometry, dual-frequency (400 kHz & 2 MHz), dual-spacing formation evaluation tool designed for LWD and measurements-after-drilling (MAD) services in all well types. The tool's symmetrical design with central receive antennas delivers direct, real-time spatial compensation, eliminating errors due to receiver channel differences.
"We're very pleased with the rapid acceptance of WPR worldwide," said Denis Biglin, Senior Vice President of Sales at APS Technology. "Our customers have now run commercial WPR jobs in the US, Canada, Russia, China and India, and we are looking forward to commercial runs in the Middle East, North Africa, Central America and South America."
WPR operates in all mud types, including oil-base and salt-saturated muds, and provides real-time resistivity with flexible transmission formats. High-resolution data is stored in downhole memory which can be retrieved and processed during trips. Downhole storage in the WPR is 32 MB, with an additional 32 MB in the MWD tool.
The tool's applications include formation evaluation, geosteering, correlation, pore pressure trend analysis, casing point selection, wireline replacement, logging while tripping and logging with and without the flow switch enabled (for air and foam-drilled wells). Remote access capabilities include diagnostics, real-time and post-survey transfer of data via WITSML and remote geosteering. APS provides a complete set of software-enabled borehole corrections and applications with WPR, including formation analysis and a well-modeling geosteering front-end.
WPR interfaces with APS's SureShot™ Directional plus Gamma (DG) MWD system and has also been successfully integrated with several third-party MWD systems.
The tool offers industry-standard antenna spacings, dielectric corrections, vertical resolution and depths of investigation, enabling computation of True Resistivity (Rt) values for fundamental log interpretation. The complete SureShot plus WPR system operates to 150°C (175°C optional), and is powered by batteries, turbine alternator or batteries plus turbine alternator. WPR is available in 3.5 inch (89 mm), 4.75 inch (121 mm), 6.75 inch (171 mm), and 8.0 inch (203 mm) nominal diameters. The 4.75, 6.75 and 8.0 inch tools offer a Pressure-While-Drilling (PWD) option which measures annular and bore pressures up to 20 kpsi (137.9 MPa).
