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 article is the fourth in a Q&A series from the SPE Research and Development Technical Section focusing on emerging energy technologies. In this piece, David Reid, the CTO and CMO for NOV, discusses the evolution and current state of automated drilling systems.

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.

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.

This paper reviews a successful managed-pressure-cementing (MPC) operation and presents findings and lessons learned.
-
Operators at a UAE field experienced several challenges while cementing production sections. A systematic approach was applied that used standard cementing best practices as a starting point.
-
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.
