Drilling
The Orange Basin and Gulf of Guinea will see most of the high-impact drilling activity planned this year in Africa.
ExxonMobil will retain its equity stakes in ongoing Bass Strait projects even as it hands off its operatorship responsibilities to Woodside Energy.
Thermal stimulation can accelerate the formation of shale creep barriers for long-term well integrity but only within a carefully controlled temperature window. This study identifies optimal thermal conditions for maximizing barrier performance while avoiding thermally induced shale damage.

The complete paper presents a drilling semantic framework that allows software solutions to achieve automatic and versatile self-configuration.
-
One of the frustrating aspects of well-productivity analysis is identifying the causes of lower-than-expected production/injection during initial well lifetime. Our task is to evaluate the multivariate aspects of well design.
-
In the current work, a rig advisory system is developed to continually improve rate of penetration (ROP) and drilling performance. An intelligent drilling advisory system (IDAS), based on a soft closed-loop solution with multiple regression analysis has been established.

For the development of the Dvalin high-pressure/high-temperature (HP/HT) gas field in the Norwegian Sea, a completion scheme using standalone screens is planned.
-
Wells in deepwater reservoirs show significant rate decline with time as the result of various causes. A diagnostic tool for quantification of factors influencing well-productivity decline is presented in this paper.
-
The success of water-conformance operations often depends on clear identification of the water-production mechanism. Such assessment can be complicated significantly when formation damage is also occurring.

SponsoredRunning casing to depth in long lateral sections is challenging, often costing operators a significant portion of pay zone at the toe of the well. This article highlights a technology that helped one operator add $120,000 to its incremental gas recovery.
-
This case study discusses the methodology that underlies the successful determination of the depths and the radial locations in the outer casing strings of multiple leaks in an offshore well.
-
This paper focuses on the preparation for, and implementation of, well-control training, while highlighting the integration of people skills into curricula and what advantages operators and drilling contractors have obtained.

This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.
