The authors discuss a production strategy in which high-gas/oil-ratio crude can be injected into the upper oil reservoirs with partial pressure depletion to achieve production enhancement and synergy among reservoirs.

The paper presents the challenges faced and overcome while drilling and testing a high-pressure/high-temperature sour-gas well offshore in an environmentally sensitive environment.

This paper presents a well-integrity-management system developed for a high-pressure/high-temperature gas field in southwest China.

Fluid identification, a critical process in fluid sampling, continues to be a challenge in temperatures above 350°F. At temperatures up to 450°F, fluid identification is currently achieved by bubblepoint and compressibility measurements, which cannot quantitatively measure contamination levels of the sample fluid. A possible solution involves using pyroelectric detect…

S13Cr tubing specimens experienced stress corrosion cracking with phosphate-based completion fluids contaminated with mud and oxygen, whereas formate-based completion fluid is compatible with the tubing.

The paper outlines specific issues, mitigation steps, and lessons learned during the development phase of a corrosion-resistant alloy pipeline.

High-strength, sour-service-grade carbon steel has been developed with outer diameter up to 23 in. and wall thickness up to 2.5 in. using a robust manufacturing process.

The two companies have collaborated since 2015 on various projects, but COVID-19 brought Velentium and Oasis Testing together for a unique purpose—to quickly ramp up the manufacturing capacity for critical, life-saving ventilators.

The project will create a foundation for further development of a thermoplastic composite pipe jumper technology for risers in permanent HP/HT subsea applications.

The cutting-edge technological developments in geothermal are devoted to drilling into deeper, hotter, and harder rock. Oil and gas expertise and know-how holds the key to cost reduction.
