Halliburton earlier this month released its EarthStar™ ultra-deep resistivity service, a logging-while-drilling technology that helps operators map reservoir and fluid boundaries over 200 feet (61 meters) from the wellbore. This is more than double the depth of investigation of current industry offerings.
Halliburton is one of the internationally renowned oil field service companies working in Guyana to support offshore exploration and production activities.
According to a statement from the company, the new service delivers a comprehensive reservoir view so operators can eliminate costly pilot holes and sidetracks, make informed geo-steering decisions in real-time and better plan future field development.
“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.”
Halliburton said 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 visualizations of the reservoir structure and fluid boundaries,” Halliburton stated.
It said that operators can deploy the service in a number of applications including geo-mapping to estimate the volume of hydrocarbons in a reservoir, identifying bypassed pay and planning for future field development. “In geo-steering applications, EarthStar helps position wells in the reservoir’s ‘sweet spot’ for maximizing recovery. Additionally, through geo-stopping, the service provides early indications of potential drilling hazards,” the company said.
