This article focuses on offshore opportunities globally and identifies the hot spots of activity. It also examines some of the key issues facing the sector and the energy supply chain, such as the need to maximize oil and gas recovery from challenging environments, to innovate, and to reduce costs.

Regulations are driving increased decommissioning activities in the Gulf of Mexico. Incomplete data is one of the obstacles in planning decommissioning. As fields have changed ownership over time, key information has been lost, creating challenges for the current operator.

The author reviews advances in produced water treatment, particularly offshore, since the 1960s. Regulations on discharge quality have been a major driver in the improvement of treatment technology.

A Separations Technology Technical Section was recently created to allow SPE members to share knowledge about emerging separations technology and its challenging applications. Interested members are encouraged to join.

As chairman of the Editorial Board for this new Society of Petroleum Engineers (SPE) publication, it gives me great pleasure to welcome you to the readership of the landmark Oil and Gas Facilities magazine.

The three papers in this issue compare the options available for multiphase pumping in both downhole and subsea environments, discuss design of electronics in deep water, and provide a case study on enhancing recovery.

Facilities engineers in the oil and gas industry have grown in stature over the past decade—the huge sums of capital we now spend have assured that. We are a growing presence as facilities become larger and more complex.

For several months, a number of us involved with water treating have been thinking about how we would like to contribute to Oil and Gas Facilities. We had in mind a regular feature with an emphasis on water treating technology.

Systematic experimental and modeling approaches to designing a safe operating strategy for a 5-km deepwater-subsea-flowline case study are presented to address unplanned shutdown and restart events for waxy-crude production.

Cost estimation for facilities depends on early concept selection and critical inputs, often complicated by uncertainty in one or more of the critical inputs. Empirical cost models and cost modeling methods using these inputs vary in degrees of scope, comprehensiveness, and robustness.
