EarthStar ultra-deep resistivity service from Halliburton

Halliburton has released EarthStar – an ultra-deep resistivity service. It is a logging-while-drilling technology that helps operators map reservoir and fluid boundaries over 200ft (61m) from the wellbore, which Halliburton says is more than double the depth of investigation of current industry offerings.

"We are excited to release what is truly a disruptive technology that enables operators to see farther into the reservoir while drilling than ever before," said Lamar Duhon, vice president of Halliburton Sperry Drilling. "The launch of EarthStar resulted from collaboration with customers to engineer a solution that enhances reservoir understanding and helps reduce well time."

EarthStar uses azimuthal electromagnetic measurements to map the geological structure around a wellbore, enhancing the operator's knowledge of the reservoir for improvement of recovery potential. The measurements are integrated with Halliburton RoxC geosteering software, which uses advanced computing methods to provide real-time visualisations of the reservoir structure and fluid boundaries.

Operators can deploy the service in a number of applications including geomapping to estimate the volume of hydrocarbons in a reservoir, identifying bypassed pay and planning for future field development. In geosteering applications, EarthStar helps position wells in the reservoir's "sweet spot" for maximizing recovery. Additionally, through geostopping, the service provides early indications of potential drilling hazards.
