The team will develop an inertial guidance system for directional drilling, based on MEMS gyroscope technology.
The focus of the project is to integrate a demonstrated gyroscope mechanical sensor design with robust readout circuits that can operate in the down-hole environment. MEMS gyroscopes enable this inertial guidance system to be positioned next to the drill bit, which is a significant improvement over existing magnetometer guidance systems that must be installed 50 to 80 feet behind the drill bit. The shortened reaction reduces drilling time and drilling cost. Finally, the system will also benefit deepwater and pad drilling by enabling a greater volume of the reservoir to be accessed from a single surface location, decreasing costs and environmental impact.

Potential Impact of the Project:
The ability to install the sensor next to the drill bit substantially shortens response time, thereby improving accuracy and reliability. Because the systemís errors do not accumulate, the range of the system can be substantially increased. Improved accuracy and reduced drilling time will accelerate the rate of commercial production, as well as exploration in emerging plays. Furthermore, with reduced drilling cost, a larger percentage of reservoirs may become economical for exploration and production. The proposed system will also benefit directional drilling for oil and gas in other locations.
