6-¾” iCruise® intelligent rotary steerable system and electromagnetic telemetry (EMT) system delivers high ROPDownload PDF
Use RSS and EMT system to drill at a high rate of penetration (ROP)
DJ Basin, Colorado
An operator wanted to drill an 8-½” mono-bore well while needing to address the drilling challenges of holding inclination in the intermediate section, drilling an 8° curve, and continue into the horizontal section. This needed to be accomplished while maintaining high rate of penetration (ROP) and utilizing a mono-bore design. Halliburton Sperry Drilling and Drill Bits Services team collaborated with the operator to provide an engineered drilling solution, and designed the bottom-hole assembly (BHA) specific to the needs of the wellbore. The design exceeded ROP KPIs of 850’/hr and reached as high as 1200’/hr in the intermediate section. It continued to deliver the required DLS to complete the curve and drill into the horizontal.
Implementing recent advancements in electromagnetic (EM) technology, coupled with the iCruise® intelligent rotary steerable system (RSS), allowed two way communication and downlinking while drilling at high rate of penetration above 1000’/hr. This technology also provided surveys while making connections which aided in reducing overall downhole hours. The motor assisted RSS by the NitroForce™ high-torque, high-flow motor paired with the GeoTech GTi55MBO drill bit design. This solution reduced well time by beating the expected KPI of the tangent section, reaching the production liner casing point, for a total of 19,830’ drilled at a final depth of 21,431’ MD. Reduced tortuosity and friction allowed installation of the production casing with no issues, helping the operator maximize asset value.
