The people in the offshore oil and gas industry have an expectation that they can work each day with zero harm to their safety or the environment. The Ocean Energy Safety Institute and the Research Partnership to Secure Energy for America have teamed up to create a roadmap to reach this goal. The Research Partnership to Secure Energy for America (RPSEA) has released its Technology Roadmap, a plan that outlines the challenges and research needs of the US onshore and offshore oil and gas industry for the coming decade.
If proven economic, solar EOR technology could represent an environmentally and energy friendly solution for California’s heavy oil producers. Oil and gas professionals may not consider solar power to be a serious threat, but it is poised to make serious inroads into the heating and cooling market. Shell invested in a Singapore solar company and signed an agreement to purchase a Texas company with solar and other renewable assets. Along with its minority stake in a company that uses solar to generate steam for EOR in the Middle East, Shell catches some rays in the Asia Pacific, US, and Oman. In thermal enhanced oil recovery there is one big ingredient: steam.
Emerging technologies from medical science and the aerospace industry could have a disruptive impact on oil and gas operations. A panel of scientists looked into these technologies and discussed their potential role in the industry.

The heat of the earth, usually from produced natural steam, heat recovered from circulated water or direct heat-to-energy conversion (on-going research).
The type of energy conversion system used to produce electrical power from a geothermal resource depends on the type and quality (temperature) of the resource. Vapor-dominated resources use conversion systems where the produced steam is expanded directly through a turbine. Liquid-dominated resources use either flash-steam or binary systems, with the binary conversion system predominately used with the lower temperature resources. When the geothermal resource produces a saturated or superheated vapor, the steam is collected from the production wells and sent to a conventional steam turbine (see Figure 1). Before the steam enters the turbine, appropriate measures are taken to remove any solid debris from the steam flow, as well as corrosive substances contained in the process stream (typically removed with water washing).
Biofuels are an alternative to fossil fuels that are produced from fats derived from living organisms. One source of biofuel that is being explored more thoroughly in recent years is microalgae. It can bloom in places where salty water, excessive sun exposure, and lack of vital nutrients inhibit growth of other crops. But the higher the concentration of algae cells, the lower the ability to absorb light. In heterotrophic conditions, the algae can use sugars, organic acids, and other organic carbons as carbon sources, replacing the need for light.
