Precise well placement improves the long-term and short-term performance of wells. With a combination of advanced measurement technologies and data interpretation from Schlumberger, well placement teams position wells in the best pay zones to maximize hydrocarbon recovery, postpone water production, and extend well life. Geosteering, fracture identification, seismic prediction of hazards and pore pressure all guide drilling to land wells directly on target.
Experts use a detailed 3D mechanical earth model (MEM) constructed of all available data—including 3D seismic, geophysical logs acquired by wireline and LWD, and drilling event analysis. The developed MEM supports drilling decisions that include well trajectory, casing points, mud window, and potential drilling risks. This model can be continuously updated with real-time data acquired while drilling, like with PeriScope bed boundary mapping service.
Real-time identification of reservoir boundaries enable directional drillers to adjust well trajectory to maximize reservoir exposure, even in thin, dipping, and fractured reservoirs. Changes in the geological structure described by geoVISION imaging-while drilling and iPZIG at-bit inclination, gamma ray, and imaging services are compared to the original models and then incorporated into the 3D reference model to update the well path while drilling. These updates also use all drilling data being acquired to continually control the geomechanical environment in the MEM, through drilling parameters to provide a highly accurate, smooth, and in-gauge borehole to optimize measurement quality. PowerDrive rotary steerable systems provide full directional control ensuring precise placement when supported with accurate data.
