Operator saves ~USD 220K and 48 hours of rig time in core recovery

Overview

With a history of high water/oil ratio (WOR) and water disposal challenges limiting production capacity in the Akacias field, an operator sought Halliburton Drill Bits and Services to help evaluate rock properties for water injection/disposal capabilities.

Challenge

Earlier disposal wells had been drilled in the K1 formation and had experienced poor injection rates when put into service. The underlying K2 formation was selected as a potential injection point but there were no rock properties available for it in the Akacias field. In order to core K2, a challenging formation transition from K1 had to be cored. After entering the K2 formation, a long interval of over 360 feet needed to be cored at maximum efficiency.

Solution

Halliburton proposed the RockStrong™ coring system because of its unique swivel assembly and anti-jamming design recognized for reliable operation in extreme wellbore environments without practical pressure or temperature limits to drill through the formation transition. This coring technology was paired with Cerebro^® coring dynamics sensor to provide downhole data necessary to create a holistic picture of the coring environment, allowing the operator to make effective, data-driven decisions on coring surface parameters and equipment.
