This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
A circular economy emphasizes reducing, reusing, recycling, and removing parts of existing systems to optimize them with respect to resource utilization. The following papers demonstrate how these pillars of a circular economy are enabling operators all over the world.
This paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.

Created by the Institute for Energy Technology in Norway in 1979, Olga was the oil and gas industry’s first transient multiphase flow model. A source of national pride, the program has been declared one of the country’s most important innovations in recent decades. -
In the realm of enabling technologies, multiphase flow modeling has proven to be one of the most important to the oil and gas industry. Without it, nearly all subsea wells would be too costly or dangerous to develop.

The presence of slug flow in the riser of the sunken Deepwater Horizon could make a significant difference in financial penalties for BP in the wake of the Macondo incident, an expert said.

Steel catenary risers (SCRs) on a large-heave-motion vessel are susceptible to compression in the riser touchdown zone (TDZ). In this paper, a finite-element-analysis modeling method is presented to simulate deformation, pipe ovality, and local pipe buckling.
-
This paper gives an overview of ongoing research activities on the subject of offshore use of composite flowlines, risers, and topside piping.
-
Riser slugging can restrict production and cause problems for downstream equipment. This paper discusses a simplified modeling approach to control of riser slugging.
-
After severe damage in a typhoon, the Huizhou oil field in the South China Sea was back on production in 5.5 months. This paper reviews how this feat was accomplished.
-
Severe slugging is characterized by large pressure fluctuations at the base of the riser and is accompanied by fluctuations in fluid delivery from the top of the riser. This instability has negative effects on downstream equipment.
-
This paper provides an overview of an engineering-design methodology that can be followed for tubular-equipment sizing and selection for use in complex wells.

This paper will demonstrate the benefit of liner-drilling technology used to drill and cement an operator’s 9⅝- and 7-in. liners in place.
