HP/HT

Researchers have developed a novel water-based-drilling-fluid system compatible with deepwater HP/HT wells in the Lingshui Block on the basis of a conventional drilling fluid and further optimization. 

A supramolecular viscosifier package has been developed that uses noncovalent associations between additives to enhance the thermal resilience of divalent brine fluids.

A Gulf of Mexico case history is presented describing the successful delivery of two deep high-pressure high-rate-designed oil wells in an ultradeepwater environment.

This paper describes both design and economic considerations that lead to the selection of vacuum-insulated tubing (VIT) or vacuum-insulated casing (VIC) for the completion of thermal wells.

Southwest Research Institute is adding a new facility to its capabilities in testing and evaluating subsea equipment and systems.

Oil and gas producers in the Gulf of Thailand face unique technical challenges. This review of papers illustrates some of the innovative solutions used in the region.

One common issue among operators in determining whether to install a managed-pressure-drilling (MPD) system for a campaign is the significant upfront cost.

Pore-pressure prediction plays an important role in well planning as exploration targets shift to deeper, overpressured reservoirs.

This paper discusses the planning and deployment of an expandable-liner-hanger (ELH) system in an offshore high-pressure/high-temperature (HP/HT) well for the first time in the United Arab Emirates (UAE).

Instead of selecting papers that were dedicated to material selection, I considered works that concentrated upon best practices and recently developed technologies that make operations in these difficult environments more efficient and far safer for crews and for the environment itself.
