Drilling
This guest editorial addresses the need for high-temperature directional drilling technologies as the number of rigs used to develop next-generation geothermal wells is set to rise in the coming years.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.

Two discoveries offshore Mexico add to April’s finding in the Norwegian Sea. -
The cementing services market size in the US is expected to drop 50% year-on-year from 2019. The significant drop in Permian Basin activity will account for 40% of the total market size reduction.

Drilling still depends on human judgment to solve many problems. Some of the problems are big, and others are related to niggling details. This article discusses three innovations aimed at improving the data flows.
-
Although multilateral and long-reach wells are common, the technological development is not complete. Effective implementation of digital technology requires complementary development of the technology itself.
-
A real-time deep-learning model is proposed to classify the volume of cuttings from a shale shaker on an offshore drilling rig by analyzing the real-time monitoring video stream.

This paper describes the analysis of sidetracks drilled in an open hole by an annular ledge formation method with a downhole motor in multilateral wells.
-
The amount of uncertainty related to directional drilling makes accurate drilling challenging, leaving much to human know-how and interpretation. Additionally, few path-planning methods in the literature consider the directional steering tool being used.
-
In the complete paper, a novel system that uses engineered features of permeable polymeric shell walls for the controlled release of encapsulated cargo is described.

This year, excellent papers have been presented, augmenting our knowledge and responding to the challenges of complex wells and efficiency requirements. At the same time as we “Strengthen the Core,” we continue to focus on design, delivery, and evaluation of cementing operations.
-
The complete paper presents a case study in which offline cementing improved operational efficiency by reducing drilling times and provided significant cost savings.
