Modular frac manifolds offer benefits for shale gas field operators

GE Modular Frac Manifold

Skid-mounted modular frac manifolds, now available from GE Oil and Gas’ Pressure Control business, are said to safely allow simultaneous frac operations on multiple well pads. Each self-contained unit’s customized array of actuated valves, blocks and frac head outlets safely isolate each well during stimulation. Multiple manifolds can be installed side by side to accommodate specific wellsite requirements.

Other benefits include:

  • A unique hydraulic jacking system to move units together for assembly, enabling quicker and safer installation
  • An ergonomic handwheel at stand level within the safety zone to minimize restrictive movements
  • Unit-connecting spools with a rotating flange for adjustability
  • A double-acting hydraulic actuator with manual override to ensure proper flow control and shutoff
  • Self-contained units that act as barriers to hold fluids and assist in preventing environmental issues.

Steam reforming technology turns oil production gas into energy

Gasreformer1

With steam reforming technology, the Wärtsilä GasReformer converts gases produced during oil production, which are abundant in heavy hydrocarbons, into a methane-rich product for use in Wärtsilä dual-fuel engines operating at full performance levels. Such gases would typically be flared and wasted.

While catalytic conversion of hydrocarbon feeds to hydrogen is a known process, the Wärtsilä GasReformer is said to represent a totally new application under very different conditions than those of the traditional process. The GasReformer is unique in its ability to convert unwanted heavier fractions from the gas into methane. By turning otherwise waste gas into fuel, the system lowers operating costs while enhancing environmental sustainability.

The Wärtsilä GasReformer was awarded the Offshore Technology Conference (OTC) 2013 Spotlight on New Technology Award.

The shale gas boom established the US as the world’s leading natural gas producer and is responsible for billions of dollars of investments in the US gas processing industry. Since 2012, the US has witnessed unprecedented growth in new gas processing capacity and infrastructure. This rise is due to greater production of domestic shale gas, which is providing cheap, available feedstock to fuel the domestic gas processing, LNG and petrochemical industries. New gas processing projects include the construction of billions of cubic feet per day of new cryogenic and gas processing capacity, NGL fractionators, multi-billion-dollar pipeline infrastructure projects, and the development of millions of tons per year of new LNG export terminal construction. Attend this webcast to hear from Lee Nichols, Editor/Associate Publisher, Hydrocarbon Processing, Scott Allgood, Director-Data Services, Energy Web Atlas and Peregrine Bush, Senior Cartographic Editor, Petroleum Economist as they discuss the future of LNG and the application of Energy Web Atlas, a web-based GIS platform which allows users to track real-time information for every LNG project.
