Accurate measurements provide full view of reservoir

Halliburton Sperry Drilling offers a wide array of LWD services to provide specific reservoir data for multiple  applications. Services include geosteering, petrophysical analysis, geomechanical analysis, and reservoir fluid characterization to help operators enhance reservoir understanding and reduce well time to maximize asset value.  Our solutions provide timely subsurface insight for real-time decisions while drilling the well.


Petrophysical and high-resolution formation imaging data provide operators with a thorough understanding of geological environments.
