Halliburton introduces EarthStar X resistivity service


Halliburton has introduced the EarthStar X near-bit shallow and ultra-deep resistivity service, part of the iStar intelligent drilling and logging platform

The EarthStar X service's near-bit, ultra-deep reservoir mapping sensor increases well placement accuracy, detecting geological changes early and enabling quick well trajectory correction to remain in the most productive zones and maximise asset value. Integrated shallow resistivity measurements allow early reserves evaluation and accurate fluid characterisation to further improve reservoir insight while lowering operational complexity and risks. 

“We listened and responded to operators to create the industry’s ‘closest to bit’ ultra-deep resistivity measurements,” said Jim Collins, vice president, Sperry Drilling. “The EarthStar X service enables accurate reserves evaluation to help place wells in the productive zone of even the most complex reservoirs.” 

The EarthStar X service accurately maps the geology in three dimensions using ultra-deep azimuthal resistivity measurements and inversion processing to geosteer, geostop, and geomap. Real-time fluid and bed boundaries visualisation can place the well in the reservoir's most productive zone and increase the section's net-to-gross value. The industry’s closest ultradeep azimuthal resistivity sensor to the bit can detect formation changes early and make timely well path adjustment to avoid early exits.
