Drilling
This paper presents laboratory-testing methods and evaluation criteria designed to improve understanding of both the origin and extent of formation damage associated with CO2 injection.
This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.

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.

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.
-
The Sidri 36 appraisal well confirmed the downdip westward extension of the Sidri 23 discovery announced last July by the Italian major.
-
India’s ONGC reported an oil find in Colombia’s Llanos Basin as well as a gas and oil discovery in Brazil’s deepwater Sergipe Alagoas Basin.
