Case Study: Western Australia Oil Company avoids faults and positions a subsea well below reservoir top with SLB GeoSphere

Operator Avoids Faults, Positions Subsea Well 3- to 7-ft TVD Below Reservoir Top Offshore Australia

SLB worked with Western Australia Oil Company, which needed to drill long horizontal offshore development wells with a maximum dogleg tolerance of 2°/100 ft while detecting multiple resistivity layers and fluid contacts in a low-contrast reservoir. The company also needed to minimize sumps and keep the well positioned for completions to TD.

SLB recommended the GeoSphere reservoir mapping-while-drilling service with real-time interpretation support to reveal subsurface bedding and fluid contact details. The service detected the reservoir top and multiple resistive layers, helping the operator avoid faults and drill the well 3 to 7 ft TVD below reservoir top; as a result, Western Australia Oil Company planned to use the same SLB service on four additional wells.
