Drilling
This paper establishes that the use of a dual-gradient fluid column during the running of large casing in an extreme-reach deepwater well is an effective method to overcome drag and enable the casing to reach total depth.
This paper presents the first global application of autonomous drilling in deepwater and the journey to reach optimal drilling parameters, integrating proprietary tools from the project’s business partners.
This paper describes the evolution of the operator’s initial PWC (perforate, wash, and cement) abandonment projects performed in deepwater Brazil.

This paper covers the 7-year history of drilling-fluids application in a reservoir drilling campaign offshore Abu Dhabi, from the early use of a solids-free, brine-/water-based mud to the recent application of nondamaging, nonaqueous fluids (NAFs) with micronized acid-soluble ilmenite. -
This study focus on the design and evaluation of a customized water-based mud (NP-WBM) using silica oxide nanoparticles (SiO2-NPs) and graphene oxide nanoplatelets (GNPs).

Recent research has put extensive focus on the magic of graphene in drilling fluids. Graphene, because of its thermal, electrical, chemical, and mechanical properties, improves mudcake stability and minimizes fluid loss that eventually reduces formation damage.
-
The advent of the rotary-steerable system (RSS) introduced an efficient way to drill both current and future wells. However, current tools still fail to replace positive displacement motors (PDMs).

The complete paper documents the development, laboratory- and field testing, and lessons learned from a project to evaluate coated centralizers.

This paper presents the results of an experimental and modeling study that demonstrates the existence of severe slugging in systems with upward-inclined lateral flow paths, such as a toe-down well.

Canadian drilling activity has fallen measurably in 2019, and the outlook is even worse for 2020, according to a forecast from the Petroleum Services Association of Canada.

The Esox-1 well encountered 58 m of high-quality oil-bearing Miocene reservoirs and will be tied back to Tubular Bells production facilities.

The Orca-1 and Marsouin-1 wells have derisked up to 50 Tcf of gas initially in place from the Cenomanian and Albian plays in the BirAllah area, more than sufficient to support a world-scale LNG project, partner Kosmos Energy said.
