Aker Solutions, Subsea 7 Win Ærfugl Subsea Scope
execution in some of the harshest offshore environments. Electrically heated traced flowlines have been developed by Subsea 7, in collaboration with InterPipe, to deliver leading insulation performance and enable cost-effective long-distance tiebacks.”The Ærfugl reservoir is mainly a gas reservoir that extends over 60 kilometers and is 2-3 kilometers wide. The project holds a total of around 300 million barrels of oil equivalent, and the field design includes capacity to accommodate future tiebacks in the area.Aker BP said total investment costs for the Ærfugl project are around
'Frog's Leg' Proves Bountiful for Aker BP
Aker BP finds up to 153 million barrels of oil equivalents in North SeaAker BP has discovered an oil and gas reservoir while drilling near its Alvheim field in the North Sea.Known as Froskelaar (Frog's Leg) Main, the reservoir is estimated to hold between 45 million and 153 million barrels of oil equivalents, and may straddle Norway's maritime border with Britain."The drilling operation will continue, and a comprehensive data collection program will be performed to determine the size and quality of the discovery," Aker BP said in a statement.When reserves are found to stretch across
DNV GL Initiative Aims to Cut Well P&A Costs
by 30–50%. The framework outlined in the RP provides the possibility for individualized, fit-for purpose well abandonment designs, a contrast to the prescriptive methodology available in the industry today. Well abandonment is driven by economic decisions, when the production of an oil or gas reservoir ceases or is no longer profitable. Authorities require that well operators perform safe and environmentally friendly operations by establishing a permanent barrier to prevent release of hydrocarbons to the surface. Traditional P&A methods are time consuming, costly and have remained unchanged
Warro-5 flows Gas Testing to Start
are now being completed in preparation for long term gas testing. Warro-5 stimulation operations were completed on 7th January and all the equipment is now being demobilized from site. The final, second stage at Warro-5 resulted in the 305,000 pounds (138,400kg) of proppant being placed in the gas reservoir. Combined with the deeper Stage 1, Warro-5 has injected 385,000 pounds (175,000kg) of proppant over an interval 4330 – 4410mRT. Clean-up flows at Warro-5, conducted over the weekend yielded a sustained gas flow with a continuous flare. Like Warro-6, the gas rate could not be measured
DNV GL's P&A Guideline Could Save O&G $ 32 bln
the next 40 years. Now a new DNV GL guideline will introduce a risk-based approach instead of the current prescriptive practice. DNV GL estimates that when combined with optimized project execution and new technology, the P&A cost can be reduced by 30-50%. When the production from an oil or gas reservoir ceases or is no longer profitable, authorities require the well to be P&A’d. The purpose is to establish a permanent barrier to prevent the migration of hydrocarbons to the surface. Traditional P&A methods are time consuming, costly and have remained unchanged despite technological
Halliburton Pleads Guilty to Destruction of Evidence
, Halliburton established an internal working group to examine the Macondo well blowout, including whether the number of centralizers used on the final production casing could have contributed to the blowout. A production casing is a long, heavy metal pipe set across the area of the oil and natural gas reservoir. Centralizers are protruding metal collars affixed at various intervals on the outside of the casing. Use of centralizers can help keep the casing centered in the wellbore away from the surrounding walls as it is lowered and placed in the well. Centralization can be significant to the quality
Supercomputer Helps Identify Subsurface Energy Reserves
deposits of oil and gas and to determining optimal extraction methods. Total's investment in Pangea will enable research scientists to develop more complete visualizations of seismic landscapes over time, while concurrently running simulations at 10 times the resolution of existing oil and gas reservoir models. Ultimately this new research should provide a clearer picture of what is happening beneath Earth's surface, allowing for more efficient upstream oil and gas exploration, as well as the discovery of reserves under more challenging geological conditions. "Total is committed to leveraging
