Halliburton Co. on July 17 introduced 3-D reservoir mapping, a new logging-while-drilling (LWD) capability that provides a detailed representation of subsurface structures to improve well placement in complex reservoirs.
3-D inversion, an advanced reservoir mapping process, reveals overlooked features such as faults, water zones, or local structural variations that can considerably alter the optimal landing trajectory of a well. In geosteering applications, the technology maximizes contact with oil and gas zones while mapping the surrounding formation to identify bypassed oil, avoid drilling hazards and plan for future development.
“This unique technology moves beyond layered reservoir models to full 3-D characterization of the reservoir, enabling accurate well placement,” Lamar Duhon, vice president of Sperry Drilling, said. “In complex formations, visualizing data in a 3-D environment helps operators significantly enhance reservoir understanding to drive better drilling decisions and maximize asset value.”
The 3-D capability originates from downhole measurements taken by the EarthStar ultradeep resistivity service, an LWD sensor that identifies reservoir and fluid boundaries up to 225 ft (68 m) from the wellbore. This range more than doubles the depth of detection of other industry offerings.
An operator in the North Sea recently deployed the 3-D capability in a field with a long history of production and water injection. The data allowed the operator to better assess the movement of reservoir fluids and visualize fault boundaries, which supported more accurate well placement and increased production.
