Multi-team solutions improve drilling efficiencies, saving average of 72 days of rig time
Challenge – Formation problems along with drilling complexities were causing time delays and high costs for the customer. Halliburton was asked to implement its technologies, engineering services, and experience to optimize drilling and increase efficiency for the operator, as well as to unite its services and subject matter experts, through project management, to develop robust solutions.
Solution – The Halliburton project management team worked closely with the other Halliburton PSL teams to capture best practices and share lessons learned. Drill Bits & Services customized polycrystalline diamond compact (PDC) bits for each section in order to drill from shoe to shoe. Sperry Drilling replaced wireline logging with Logging-While-Drilling (LWD) tools, and cured losses with new technology that optimized BHA and mud motor selections. Baroid engineered and implemented drilling fluids that combated the formations that were susceptible to the losses, along with stability concerns, sulfurous water influxes, and shale swelling. With its Circumferential Acoustic Scanning Tool (CAST™) technology, the Cementing team provided the best bonding results for the production casing and liner. The Wireline and Perforating team and the Completion Tools team provided improvements in drilling optimization. This PSL collaboration produced drilling efficiencies that ultimately reduced both well delivery time and nonproductive time (NPT).
