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.

Saudi Aramco’s papers on new well technology offer glimpses at the challenges of developing its unconventional gas resources.

This paper describes a low-impact, nonaqueous drilling fluid (LIDF) designed to minimize equivalent circulating density (ECD) increases and associated risks in deep water by reducing the effect of cold temperature on fluid viscosity.
