Recently, the company announced the availability of precalculated MagCube™ in-field referencing (IFR) models for meas- urement while drilling (MWD) surveys over seven U.S. onshore basins and plays: Bakken, Eagle Ford, Haynesville, Marcellus, Niobrara, Permian, and Woodford. CGG’s MagCube magnetic referencing system combines a global geomagnetic reference model with local magnetic survey data to deliver declination (dip), inclination, and total field values at depth. These cubes of subsurface vector magnetic field infor- mation wi l l help with MWD surveys for directional dri l l ing. Accurately knowing a well’s trajectory while the well is still being drilled could save costly sidetracks, and even prevent collisions with other wells in tightly drilled shale plays. The MagCube models include an estimation of positional uncertainties, allowing clients to design more closely spaced drilling programs. As laterals get longer and the development of stacked reser- voirs becomes more common onshore, well paths are getting smaller. The smaller the target, the more important it is to know where the wellbore is in real-time. It also eliminates costly rig time to run separate post-drilling gyroscopic surveys. According to Greg Paleolog, senior vice president for CGG Multi-Physics, the IFR tool is a great example of working closely with drilling companies, as well as gas and oil producers, to create the best geomagnetic models of the most prolific onshore U.S. unconventional basins. It’s cost-effective and timely, which significantly reduces drilling uncertainties and costs. “With the adoption and application of geomagnetic technology to downstream oil and gas drilling, CGG is taking the lead once again to meet client business needs in a very important and expanding market segment,” he stated.
