Drilling
This paper presents laboratory-testing methods and evaluation criteria designed to improve understanding of both the origin and extent of formation damage associated with CO2 injection.
This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.

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.

Stories from the IADC/SPE Drilling Conference look at how the next generation of engineers is performing, the hottest well ever drilled, and the art of translating drilling numbers into executive reports.

As leaders in digital drilling analysis push into real-time data analysis and digital controls, they are finally confronting data-quality problems. Humans are better than machines at dealing with ambiguous readings.

Sensor technology in the oil industry changes infrequently. Improvements in MEMS sensor technology are creating rapid momentum toward the use of tiny, rugged, and inexpensive sensors to replace larger, costlier, and more fragile legacy-technology sensors in directional drilling.

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.

A producer and a service company have collaborated to develop a downhole system to merge multilateral technology and intelligent completions to create “smart laterals.”

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.
