This is achieved using a hybrid data-physics model created using sequential design of experiment (DoE), combined with extensive experimental work on fluid formulation...

... Despite pumping cement slurries with densities as low as 1.20 sg and utilizing significant volume excesses, the former operator was still unable to ensure that the cement reached the seabed. Consequently, the failure to achieve this objective necessitated extremely costly remedial top-up...

... factors and user-centric design in drilling operations in the past. Through identifying existing pain points, new design concepts for driller's control cabins have been developed. Interviews and rig visits were conducted for the assessment of the current situation, comprising questions about the human...

... deployment that helped complete the longest liner in the deepest drilled well in the Offshore Umm Shaif field, UAE. The recent well design of a 30,000+ ft well rendered the operator's previous approach of using the drill pipe swivel irrelevant. While the market offers casing swivel technology to reduce drag...

... repairs. This paper reviews a field study conducted by a major operator to evaluate a novel, low thermal conductivity-coated drillpipe for long-lateral drilling operations in the Haynesville. The paper reviews the development of the low thermal conductivity coating, built on established coating solutions...

... and process instability. This paper is a case study on how to properly setup and apply an auto-driller presented with offshore drilling data. Most common auto-drillers have two main modes namely WOB and ROP. An operator can select the desired mode of operation, or in some auto-drillers, the mode switches...

... in value globally each year [ 1 ]. Similarly, a study by the Boston Consulting Group (BCG, see [ 2 ]) found that the adoption of automation and digital tools in drilling operations can reduce drilling costs by up to 15% and improve well delivery time by as much as 30%. The International Association...

... permanent facilities such as compression stations and producing wells now operate on grid power, often with a renewable energy component. Despite clear benefits, few drilling rigs have strayed from traditional diesel power to make the switch to the grid as the source of energy for drilling. As fields get...

... Abstract This paper presents a method using surface and downhole data to enhance responses to lost circulation events in drilling operations, which are significant challenges leading to nonproductive time and financial losses. Lost circulation costs the oil and gas industry approximately USD 1...

... automated rotary drilling with minimal human intervention. The technology has been utilized on over 100 wells in multiple basins in different formations in collaboration with several major Oil and Gas operators. Achieving optimal Rate of Penetration (ROP) improvements in the 1-22% range in the lateral...

... Abstract This study examines the automation of the traditionally manual slip-to-weight (S2W) and weight-to-slips (W2S) sequences in drilling. Historically, best practices for these sequences were individually maintained. In alignment with a major operator's protocol in the Midland Basin, our...

Well construction generates many documents that are shared cross-functionally between these different groups. A regulator may receive an as-drilled plat from a well planner, using surveys from an MWD operator...

In the context of well construction operations, where a substantial volume of data is generated and stored across various...

... Abstract As operators actively manage their costs of drilling, reducing cost in one area can increase it in another. Millions of horizontal feet drilled across North American shale basins has effectively eradicated existing drill pipe fleets. In addition, the rise of 5-1/2 inch variants in land...

... for further changes and improvements to the drilling program. After MPD was implemented, these changes enabled the operator to complete a pace-setter, one-run build and lateral section with a intermediate drill out time to rig release (RR) of 5.3 days. Using MPD for performance drilling can save days per well...
