In the Marvel Universe, Thanos takes the lead as the most powerful character whose main objective was to bring stability to the entire universe. In the oil and gas industry, Ulterra takes the lead on designing drill bits to help operators achieve their drilling objective; whether that is to bring stability, speed, or durability to their drilling operation.
Whichever the goal, Ulterra’s team offers proper bit selection to improve drilling efficiency and deliver value to operators worldwide. Recently, Ulterra’s 8.5” SPL616 was referred to as the “Thanos” of the oil and gas drill bit industry by Pertamina Hulu Mahakam (PHM), an Indonesian Government-owned Oil Company.
With operations in Indonesia, Pertamina Hulu Mahakam offered Ulterra their first field test in East Kalimantan. More specifically, PHM consulted with Ulterra for their drilling operation in the Tunu field. Ulterra’s team suggested their 8.5” SPL616, to ensure bit durability, aggressiveness, and stability throughout the entire drilling operation. Equipped with SplitBlade™ and CounterForce™ technology, Ulterra’s team was confident in supplying PHM with a reliable and proven drill bit design.
Initial Field Test Results
Utilizing Ulterra’s 8.5” SPL616, PHM surpassed their first drilling objective of 1,750 m, drilling 1,804 m. in just 24 hours with an average ROP of 127.5 m/hr. In the upper section, Ulterra’s SPL616 demonstrated a very impressive directional response with torque slightly increased in normal trend. Drilling the rest of the interval to a total depth of 4,013 m, Ulterra’s SPL616 drilled 2,611 m in 28.48 on bottom hours with an overall average ROP of 91.7 m/hr.
The SplitBlade and CounterForce design along with technical limit operations and optimizations by Pertamina, rig contractor and drilling crew, and directional company resulted in 2 records broken. PHM achieved a new drilling footage record in 24 hours, as well as a new field ROP record. Altogether, Ulterra’s SPL616 demonstrated great performance, saving PHM roughly 1.3 days of drilling time.
Following this initial run, PHM gave another opportunity to Ulterra to prove the initial results were not a fluke while testing the bit to break its own record. PHM utilized another SPL616 on RSS BHA to drill 2,132 m., outpacing the record set by PHM and Ulterra aforementioned. Finishing the well to total depth, PHM continued to drill 2,905 m in just 31.6 on bottom hours. The combination of optimized bit design, enhanced drilling parameters, fast connection and survey, and cooperation of PHM, drilling contractor, and service companies yielded a record-breaking performance. The bit design will be enhanced to drill more challenging and deeper wells in PHM drilling operations.
