Plans were developed to produce multiple deepwater reservoirs with vastly different fluid properties from a subsea development in 3,100 ft of water in the Gulf of Mexico.

The Mensa field is a deepwater Gulf of Mexico (GOM) geopressured-gas field, producing from Upper Miocene sand with faulted four-way closure.

The Hadrian-5 prospect in the US Gulf of Mexico was drilled in approximately 7,000 ft of water as one of the first Gulf of Mexico wells drilled after a deepwater moratorium was imposed after the Macondo disaster.

Riser margins were abandoned when fluid columns in risers became too long with increasing water depth accessed when floating drilling units with subsea blowout preventers (BOPs) moved to deep water.

The Goliat field will be the first offshore oil field in the Barents Sea and the world’s northernmost offshore oil field.

With exploration in harsh environments and consequent high-pressure and high-temperature conditions, calculating reservoir properties has become complex and changes in pressure-transient response need to be understood and appreciated by taking appropriate measures.

We all know that things have changed significantly for offshore drilling and completion in the last 3 years. Regulations have been reviewed, and operational procedures and requirements have changed.

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.
