Drilling
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
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.

UK’s active 30th Licensing Round resulted in the award of 123 licenses to a diverse set of 61 companies—an outcome that UK government officials hailed as more proof that interest is picking up in the aging North Sea. -
CoreAll's Intelligent Coring System uses a suite of sensors to analyze reservoir cores samples as they are being acquired, and a communication system that sends these data to the rig in real-time.

Coring is essential to offshore exploration programs—but sometimes cores are taken from the wrong formation or return to surface in poor condition. One firm thinks it can solve these costly issues with a first-of-a-kind coring device that uses logging instruments that add accuracy and integrity.
-
The Bureau of Safety and Environmental Enforcement is proposing to update regulations covering offshore oil and gas drilling operations.

This paper reviews the technology trends in cement-job evaluation using logging tools and considers the main advantages and concerns associated with each technology.

As I read through the abstracts and papers that have been presented in the past year, I notice several key themes: verification of cement placement, development of new materials as a barrier, development of new additives to improve the cement barrier, and enhancement of existing techniques.

As the resources that the industry develops become increasingly challenging, access to a broader range of options and new and developing approaches allows more-efficient and -effective recovery.

The influx-management-envelope (IME) concept is an advanced, innovative way to assess influx conditions in managed-pressure-drilling (MPD) operations, offering an improved tool for the decision-making process.

This paper discusses the successful design, laboratory testing, and performance of an innovative, low-solids, organophilic-clay-free invert-emulsion fluid (OCF-IEF) used to drill the reservoir section of an extended-reach-drilling (ERD) well.
-
Current long-reach technology already has a large effect on oil recovery. Many possible improvements, however, remain, and we see new contributions every year.
