Offshore/subsea systems
This paper presents a flexible, highly cost- and energy-efficient method of gas separation and CO₂ capture from many different gas mixtures with a large range of CO₂ concentrations.
This work introduces a novel predictive methodology combining historical metocean data with real-time riser analysis for shallow water dynamically positioned rig operations.
This paper documents the testing, integration, and field deployment of a metal expandable packer used as an openhole toe isolation plug in a deepwater well under high-pressure, high-temperature conditions.

As subsea electric lines age, they are prone to cracks that allow seawater in, reducing their effectiveness, and if the leaks are bad enough, they can shut down operations. -
To support subsea processing of heavy crudes, an inline electrocoalescer was tested for separation of water droplets dispersed in the crude oil.
-
Projects are being delayed or deferred due to low oil prices, which is affecting the market for subsea, umbilicals, risers, and flowlines (SURF).
-
In this paper, an analysis of the selection of integrated template structures (ITSs) for Arctic environments is presented.
-
This paper describes the architecture of the Lucius Gulf of Mexico subsea production system and the drivers behind it.
-
This paper addresses the standardized features applied to the 10,000-psi-rated subsea-system components at the Espirito Santos FPSO in the Campos basin offshore Brazil.
-
The need for standardization of subsea equipment has never been greater. With the drop in oil prices, cost reduction has become critical.
-
This paper posits a design method for subsea equipment governed by American Petroleum Institute (API) Specification (spec.) 17 (and particularly 17D).
-
To provide a best practice approach aimed aimed at reducing delivery time and production costs and improving material quality, a joint industry project led by DNV GL resulted in a recommended practice for steel forgings in subsea applications.
-
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.
