Drilling
Operators aren’t rushing to drill, even as the closure of the Strait of Hormuz drives oil prices up.
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.

The Irving, Texas-based supermajor plans to cash in on its expanded foothold in the Permian Basin, aided by a big reduction in the US corporate tax rate. -
Overcoming numerous regulatory hurdles, Cuadrilla Resources is pressing ahead with its plans to fracture a well in the UK for the first time since 2011.

Major oil discoveries by Armstrong Oil & Gas and ConocoPhillips have compelled the US Department of the Interior to reassess its estimate of undiscovered, technically recoverable resources in parts of Alaska.

Nonaqueous drilling fluids have been used extensively by the industry, particularly in complex drilling scenarios. They carry some concerns, however, with implications for well integrity.
-
Managed-pressure drilling (MPD) challenges the conventional drilling paradigm, along with drilling-contractor and operator policies and standards. Conventional drilling practices for connections, flow checks, tripping, and well control have been long understood and standardized.
-
In this study, pressure-while-drilling technologies are combined with software simulations to differentiate drilling-fluid thermal expansion, wellbore ballooning, and formation influx during riserless drilling operations.
-
Thermal-well operations come with significant additional complexity in regard to maintaining wellbore integrity and hydraulic isolation from other formations.
-
A fluid technology has been developed to deposit a thin, impermeable barrier over the pores and microfractures of weak, underpressured, and otherwise troublesome formations to maintain wellbore stability and reduce formation damage.

Finding niches that provide a competitive edge over larger operators has enabled Talos Energy to leapfrog into a powerful position with Mexico’s first offshore wildcat discovery.

Bottomhole assemblies (BHAs), as part of the drilling system, have dominating effects on the functionality and effectiveness of other system components. BHA design, usage, and monitoring must promote drilling-system compatibility, efficiency, and reliability.
