HP/HT

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.

One would think that, in these challenging times, high-pressure/high-temperature technology and projects would be put on the back burner, with everybody chasing zipper-fractured barrels from shale. Well, it is not so.

This paper describes a high-pressure/high-temperature (HP/HT) expandable liner hanger product that offers metal-to-metal and elastomer sealing capabilities at the liner top in the host casing.
