Abstract Drilling with a gas cap over the Natih formation in Oman often results in excessive flat time. Using the current dynamic fill equipment to deal with kick and loss scenarios leads to extensive nonproductive time on the rig. Managed pressure drilling (MPD) is a well-established drilling technology, and diverse variants exist to suit different requirements. All those variants use the rotating control device (RCD) as a common piece of equipment, but their procedures are different. The pressurized mud-cap drilling (PMCD) technique in the Natih formation replaces the need for traditional dynamic filling technology. The PMCD application enhances the drilling and completion processes by reducing flat time when total downhole losses are experienced. This paper elaborates on PMCD as a proven drilling technique in total loss scenarios when drilling with it for the first time in the Natih formation in Oman. It describes the PMCD process, the associated equipment, and the results of the inaugural application in the Qalah field.

No Wait

As the new operator of the Mahakam Block started in 2017, Pertamina Hulu Mahakam (PHM) were challenged to ramp up operations in order to combat massive production decline. At the same time, reducing well cost was also a paramount importance to ensure that the economic targets of the wells were achieved following the reduction of well stakes. One of the remaining unsolved enigmas is how to achieve No Wait-on-Cement (NO WOC) on surface diverter section as this will create a lot of rig time saving both on single well and batch operations. The project begins with several different kinds of proposal until the best solutions were identified fulfilling safety, simplicity of operations and acceptable cost and finally were put in place with very satisfying results. The main key principle is conversion wellhead stages following well architecture while there were several modifications of casing hanger, adapter, additional materials & modified procedure. Rig time saving, additional operational gain and a promising new “breakthrough” of drilling technique become a significant impact of the successful effort. Now the method has become a standard in PHM operations and has already been integrated to SDI (Standard Drilling Instruction). The merit of this endless hard work could possibly be gained by other operators as it will create more added values both tangible and intangible.
