MWD Systems Data Acquisition – Surface Systems GE MWD and LWD systems transmit directional measurements and logging data for real-time display. In addition, data are stored at higher resolution in the tool memory for retrieval at surface and merged with depth data to provide final logs. A comprehensive set of surface equipment is supplied with each system. Transmission Systems – Positive Pulse GE offers industry-proven positive-pulse transmission systems to send computed surveys or raw data to the surface in real time.

Pilot MWD System The Pilot MWD system offers an entry-level option for customers wishing to use proven GE technology. The Pilot MWD system provides full MWD capability with optional gamma upgrade for drill collar sizes ranging from 3 ½ in. (89 mm) to 9 ½ in. (241 mm) O.D. • Retrievable/Reseatable Wireline-retrievable MWD probe reduces lost-in-hole risk and eliminates tripping to replace equipment. • Motor-Driven Pulser Pulser exerts up to 100 lb. force for improved LCM tolerance. • Power Efficient Up to 400 hours battery life with Pilot MWD system, enabling prolonged runs and reducing battery...

Pilot MWD System The surface system is compact for efficient rig-up and provides a user-friendly interface for operators. The rig floor display (RFD) is based on a rugged computer integrated with GE proprietary hardware and software. The RFD is installed in a compact, toughened enclosure with a touch-screen interface. Two-way wireless communication may be added to provide remote monitoring and additional logging functionality with the gamma module. • Compact with Few Components Designed for rapid system rig-up, the small RFD footprint allows versatile installation on the rig floor. Simple user...

Tensor MWD System The well-established and reliable Tensor MWD system is acknowledged as the industry standard in retrievable MWD systems. Comprised of a downhole probe-based tool with a bottom-mounted pulser, modular tool components and associated surface systems, the Tensor directional system provides real-time azimuth, inclination and tool face data via positive mud pulse telemetry. Plug-and-play options are available to provide gamma and resistivity for LWD applications. • Retrievable/Reseatable Wireline-retrievable MWD probe reduces lost-in-hole risk and eliminates tripping to replace equipment....

Tensor MWD System The Tensor surface system hub is located in a safe area and is an extremely reliable, efficient receiver and decoding system. Color LCD rig floor display, surface sensors and peripherals are all connected to the hub. A comprehensive software interface ensures both surface and downhole systems can be easily programmed for various tool combinations and telemetry parameters. • User-Friendly Software Robust decoding and simple tool programming interface results in quick and effective operator training. • Downlink Telemetry Change Operator can change data rates and telemetry parameters...

Tensor LWD System The Tensor MWD system can be expanded to fulfill specific LWD project requirements by adding the Scinturion Gamma Module and the Centerfire* resistivity tool. The LWD system is specified to 175°C (347°F), uses a standard solenoid-driven pulser with the gamma module and a special solenoid-driven pulser with a wet connect fitting to connect to the Centerfire tool. Four tool configurations are possible with the Tensor LWD system: 1. Directional-Gamma with the gamma tool placed above the pulser and using two battery modules. 2. Directional-Gamma-Resistivity with the gamma tool placed...

Centerfire Resistivity System The Centerfire resistivity system uses an industry standard transmitter-receiver design to provide multiple depth of investigation (DOI) borehole-compensated resistivities. The fully retrievable probebased directional MWD module is situated above the resistivity tool and can be removed from the tool string with the logging data downloaded at the surface even if the rest of the bottomhole assembly becomes stuck. Centerfire Key Features • Eight borehole-compensated resistivity measurements. • Temperature rated up to 175°C (347°F). • Retrievable probe-based directional...
