i-TEC Launches Revolutionary Well Technology

I_TEC.jpg

Stimulation of offshore well achieved in 1.5 days, in contrast to the normal 40-50 days.   Well technology company i-TEC has developed a unique, new lower completion ball drop sleeve system which can radically reduce the time it takes to stimulate a well. The i-Frac system allows operators to bring wells in tight formations on line much more quickly than other methods, resulting in potentially huge cost savings and earlier production revenues. The system recently reduced stimulation of a North Sea well on the Norwegian Continental Shelf to only one and a half days, as compared to the normal of 40-50 days. It allows for more than 20 sleeves per stage to be installed in a cemented liner and opened sequentially with a single ball. A number of stages can be run in a single well.   The recent installation was in early paleocene and late cretaceous, carbonate formations in the Norwegian sector of the North Sea. The technology also has huge potential for global shale oil and gas plays, particularly in the United States, where in some tight shale fields it could allow an operator to fracture twice as many wells in a year compared to traditional methods. The recovery of oil and gas in limestone and tight shale formations is accomplished by drilling horizontal wells to increase the well-reservoir contact. Each well is divided into zones which are individually opened to carry out a controlled and efficient stimulation of the formation rock.  


SHI Secures Order For FPSO

SHI received an order for a floating production storage and offloading (FPSO) facility worth US$140 million from Husky Oil Operations Ltd. of Canada on the 31st. As a competitive solution for the development of offshore oil and gas resources capable of the production, storage and offloading of crude oil and gas, an FPSO is a special facility suitable for the development of a medium size deep-sea oil and gas field due to its mobility


Oil Search and Halliburton Renew Contract

Oil Search Limited and Halliburton have signed an agreement to renew an alliance that was originally formed in 2004. The multimillion-dollar contract covers three years, with the option for two additional years. The agreement calls for Halliburton to provide a full range of subsurface services, including drilling and formation evaluation, slickline, fluids, cementing services and production enhancement in Papua New Guinea where Oil Search is the industry leader in oil and gas exploration and


Statfjord Celebrates 30 Years on Stream

Thirty years after the Statfjord field started production, one of the largest oil fields in the North Sea has now become a gas field. “On 24 November 1979 we brought one of the North Sea’s largest oil fields on stream,” said Øystein Michelsen, executive vice president for Statoil’s Exploration & Production Norway business area. “Today we operate a field where 65% of the total output is gas. A whole new era in Statfjord’s history has begun


Maersk Taking $1.7b Charge on Brazil Assets

Full-year underlying profit guidance unchanged; writedown raises questions over company's oil strategy. Danish oil and shipping group A.P. Moller-Maersk moved to shrink its Brazilian petroleum operations on Tuesday, selling its stake in its only producing Brazilian oilfield and saying it will write off $1.7 billion of investments in the country. The write-off affects two exploration areas, Itaipu and Wahoo, which failed to deliver on oil volume expectations, and the Polvo field


Cairn Confirms Successful Senegal Appraisal

  Cairn informed that the successful testing of the SNE-2 appraisal well offshore Senegal with positive results. Operations have been safely and successfully completed following drilling, coring, logging and drill-stem testing (DST). The well is now being plugged and abandoned. Following this first successful appraisal well, resource estimates for the SNE field will be fully revised and  announced after the results of the further appraisal activity


New Technology from Camcon

Camcon Technology unveiled a new technology application designed to increase the volume of oil that can be recovered from the world's reservoirs as well as reduce operating costs. Developed specifically for the oil and gas industry, the Camcon Intelligent Gas Lift configuration is part of Camcon binary actuator Technology (BAT). The application aims to enhance the recovery of oil from reservoirs by introducing gas injection management capabilities to improve extraction flow


Petrobras Hits in Deepwater GOM

Petrobras announced the discovery of oil and gas in ultra-deep waters in the Central Gulf of Mexico, in the U.S., via its Petrobras America Inc. subsidiary, based in Houston, Texas. The discovery was made via the Stones # 3 well, drilled to perform the exploratory assessment of the Stones discovery, which is operated by Shell and located in Block WR 508, in ultra-deep Walker Ridge Quadrant waters. Petrobras America Inc. holds a 25% stake there


Another discovery in the Gullfaks area

This is the fourth infrastructure-near discovery in the Gullfaks area in a 10 month period.

Statoil’s drilling of the Skinfaks South well in the North Sea has been completed and the estimated volume is between 1.9 and 6.9 million barrels of oil equivalents. This is the fourth infrastructure-near discovery in the Gullfaks area in a 10 month period.   Light oil has been confirmed in Middle Jurassic reservoir rocks (Brent group) and a 80 metre high column in good-quality reservoir rocks. "We are currently evaluating how this discovery can be connected to the existing


OPTION Attracts New Partner for Oil Recovery

This Project combines novel technologies and recent scientific discoveries with the ambition of creating a game changer in the oil field

  OPTION (Optimizing Oil Production by Novel Technology Integration) aims to significantly improve simulation tools for the prediction and control of the flow between the horizontal wells and the reservoir – with a focus on enhancing oil recovery. As part of their investment in the project, DONG Energy will contribute with the complete subsurface dataset from the Siri and Stine fields, located in the Danish sector of the North Sea.
