Subsea capping stack handles deepwater well control

Wild Well Control, Inc., a Superior Energy Services company, has unveiled its new subsea capping stack for response to global, deepwater, well control incidents. The subsea capping stack, located in Singapore, is a part of Wild Well’s comprehensive emergency response system, WellCONTAINED, which provides experienced personnel and equipment to plan, prepare and respond to global subsea well control events. The system not only includes the physical capping stack and equipment, but also technical planning, advanced engineering and response training. This is the firm’s second unit; the first capping stack unit is located in Aberdeen, Scotland. The full intervention system at each location includes a capping stack, debris removal shears, hardware kits for the subsea application of dispersant and inhibition fluids at a wellhead and ancillary equipment. This 183/4-in., 15K capping stack is designed for subsea use, down to 10,000 ft. The system is maintained in a state of readiness and can be transported quickly by sea or air.

H₂S removal solution works for pre-salt layers

Clariant’s H₂S Risk Management System removes hydrogen sulfide in offshore operations, and is designed for both subsea activities and offshore topside natural gas processing. Clariant developed the H₂S removal process in two stages, which include the onshore and offshore delivery logistics, and managing the removal and disposal of residues. The first stage injects liquid H₂S scavengers into wells, so that cleaner hydrocarbon fluids arrive topside. The second stage uses a catalyst (a solid adsorbent) on the offshore gas processing plant, to purify the gas and eliminate H₂S residues, given that the gas cannot be transported to an onshore facility, if it contains such impurities. Management of the H₂S removal process by the company’s Brazillian facilities will contain over 90% local content.

Extended-range ESP manages production decline

Baker Hughes has released the FLEXPumpER extended-range pump, which expands the operating range of a single, electrical submersible pumping (ESP) system. The new pump operates with a flow range from 50 to 2,900 bopd. As production rates from unconventional oil wells decline, operators typically switch out pumping units, or, even artificial lift production methods, to accommodate the various flow ranges. The FLEXPumpER design features patent-pending advanced turbulence mitigation (ATM) technology, to increase pumping efficiency and reduce gas locking, as well as a redesigned bearing system, to withstand the high temperatures generated in the pump during short-term operation with gas slugs. Particle swirl suppression ribs in the diffuser provide abrasion resistance by reducing the buildup of abrasives that can cause erosive wear.

Hydraulic fracturing system with real-time monitoring, analysis

Tendeka has launched FracRight, a hydraulic fracturing system with real-time DTS monitoring and the Quest software suite, enabling the collection and analysis of stimulation data in unconventional reservoirs. The FracRight system is a fully integrated, frac sleeve solution for selective multi-zone stimulation in open hole or cased hole applications. It allows for the installation of multiple sleeves for each stage to be fractured. The sleeves are shifted open by pumping a ball from surface, allowing for subsequent stimulation of the selected stage, either from a single sleeve or a cluster of sleeves. The FracRight system can be integrated with Tendeka’s real-time, distributed, fibre optic, stimulation monitoring service, to provide evaluation and management of multi-zone completions.

Trailer unit enables processed field gas

Croft Production Systems, Inc. has taken an innovative step in the way that gas and oil are processed.  This mobile version of Croft’s Fuel-gas Conditioning Unit, the FCS-500M, is trailer-mounted and designed for the field processing of natural gas for use in gas-powered engines. The first trailer manufactured will be accompanying a drilling rig, onsite, to provide processed field gas, to reduce diesel consumption in the rig’s bi-fuel diesel/natural gas generators. The FCS-500M cools the gas and separates free liquids, utilizing an Ambient Cooling System (ACS). The unit then dehydrates, using a simple, reliable, Passive Dehydration System (PDS). Finally, a controlled pressure drop chills the gas and cold-separates high-BTU gas components in the Joule Thomson System. All components are piped together, with controllers and regulators included for quick set-up. This system also can be used for temporary processing of small wellstreams.

Zero-leak check valve

The Lee Company’s 375 Zero Leak Check is a stainless steel, miniature check valve, featuring a seat with an elastomeric seal.  The 0.375-in.-diameter valve weighs 11 grams and can flow 1.9 gpm at 25 psid, while handling system pressures up to 5,000 psi. The valve is available in forward and reverse flow configurations. 

New contaminant reduction service

Petro Chemical Bio-Diagnostics (PC Bio) is offering a new risk mitigation service—a solution to bacterial contamination challenges. The PC Bio system includes sample characterization testing, bio-treatment efficacy testing, corrosion testing, and live bacteria enumeration capabilities. PC Bio allows users to identify specific bacteria in a given field, well or water sample, and then decide which bio-treatment will have the greatest efficacy. PC Bio is a partnership between Vivione Biosciences, Inc. and the Institute of Environmental Health, Inc. 

Shale-specific software offers end-to-end E&P workflow

Schlumberger has released Petrel Shale, a customized user interface and toolset, engineered for exploiting shale resources. Petrel Shale is scalable and designed to optimize operations by linking the data and disciplines. Users can integrate geological, geophysical and production data to define sweet spots, automatically plan well locations and analyze production trends.
