Drilling
Developing the theory of mechanical specific energy from the perspective of instantaneous drilling power rather than the compressive strength of the formation leads to an improved understanding of drill-bit mechanical efficiency.
The oilfield service company will supply power plants capable of electrifying 180,000 US homes with geothermal energy.
This paper presents an efficient mathematical optimization method for well placement that maximizes contact with the productive zones for the best locations in the reservoir.

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.
-
Hess is testing whether it can drive drilling improvement by combining drilling rigs equipped with automated functions and humans determined to find a way to beat the programmed drilling.

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.

Directional drilling and measurement-while-drilling technology has become so democratized in the Texas shale sector that no provider holds more than 8% of the market share.
