Drilling
This paper provides an account of the design, implementation, and operational insights from an enhanced geothermal system proppant stimulation targeting a volcanic, dry rock setting with an approximately 330°C bottomhole temperature.
This study evaluates the feasibility of drilling a closed-loop, unconventional geothermal system in the Pannonian Basin basement of Romania.
The paper describes a multientry multistage fracturing technology developed to enable longer laterals, increase stage counts, improve stimulation efficiencies, and derisk operations.

Acquiring data from an abandoned subsea well has been done before, but never quite like this.

The $10 million/year contract covers the inspection and mobilization of casing and tubing at two Norwegian sites and includes extenstion options in 2020 and 2022.

The complete paper describes a recent directional coiled-tubing drilling (DCTD) job completed for an independent operator in the Appalachian Basin.

Plug-and-abandonment (P&A) operations can be expensive, leading to negative net present value. Historically, P&A operations in the North Sea—estimated to hold some 3,000 wells of declining production—were performed with either drilling or workover rigs.

Shell made its sixth discovery from the Norphlet formation in the deepwater Gulf of Mexico, where the firm’s newly arrived Appomattox platform just 13 miles away presents a tieback opportunity.

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.

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.
