Shells Announces Drilling at Sivulliq
Oct 5, 2012 – Shell announced the Kulluk (shallow-water semisub) has spud the top-hole section at its Sivulliq prospect in Alaska’s Beaufort Sea. The Noble Discoverer is currently engaged in the same type of work at the Burger prospect marking the first time in over 20 years that two rigs have been drilling off the Alaskan coast simultaneously. Last month Shell announced that its containment dome had been damaged during testing. Because of that, the rigs aren’t able to drill into possible hydrocarbon bearing formations, so for now they are restricted to drilling shallow top-hole sections in preparation for the drilling season next year.

Fairfield Optimistic About Dunlin Enhancements
Oct 4, 2012 – To date, Farifield Energy has invested $113.3 million in an effort to revitalize the Dunlin platform. For the first time since early 2000, the operator will be able to use its own independent power generation system to achieve significantly higher and sustained water injection performance. A new fuel gas import system and modified water injection system are expected to boost production of the mature field to around 10,000 bopd. Additional work has included platform and subsea modifications and a recent acquisition of a new 3D seismic survey over the field. The data will help support an exploration program that could result in additional wells being drilled and tied-back to the platform.
Project Details: Dunlin
Oct 4, 2012 – Aker Solutions has been awarded a $52.6 million contract by Statoil for the delivery of five subsea trees and 11 control modules to the Visund field on the Norwegian continental shelf. Included in the contract is an option for four additional subsea trees. The contract is a call-off from an existing frame agreement between the two companies signed in 2007. The trees will incorporate Aker’s most advanced subsea technology which will facilitate oil and gas production at a more efficient level and allow greater recovery of reservoir data. Manufacturing of the Visund trees and control modules will take place at Aker Solution’s Tranby and Aberdeen facilities respectively.

Statoil Says No Increase for Melkoya Capacity
Oct 2, 2012 – Norwegian oil major Statoil announced Tuesday that it and its partners have decided to stop work on a capacity increase at the Melk??ya facility serving the Sn??hvit license in the Barents Sea after they concluded that current gas discoveries do not justify the expansion of the field. Statoil said that over the last 18 months, the Sn??hvit license partners carried out studies for the expansion of gas exports from the field, and that increased capacity would enable the accelerated gas production of increased reserves in the Sn??hvit license. Thorough studies were carried out both on an LNG train and a dew-point facility/pipeline solution, while considerable resources were devoted to finding solutions that could make a capacity expansion possible. However, the license partners have now decided the immediate future will focus on optimizing and upgrading the existing LNG facility at Melk??ya. Statoil, the operator, holds 36.79 percent of the Sn??hvit license, while Petoro, Total E&P Norge and RWE Dea Norge hold 18.4 percent, 12 percent and 2.81 percent respectively.

USGS Releases Survey on Utica Shale Gas Resources, USA
The Utica Shale contains about 38 trillion cubic feet of undiscovered, technically recoverable natural gas (at the mean estimate) according to the first assessment of this continuous (unconventional) natural gas accumulation by the U. S. Geological Survey.
The Utica Shale has a mean of 940 million barrels of unconventional oil resources and a mean of 9 million barrels of unconventional natural gas liquids.
The Utica Shale lies beneath the Marcellus Shale, and both are part of the Appalachian Basin, which is the longest-producing petroleum province in the United States. The Marcellus Shale, at 84 TCF of natural gas, is the largest unconventional gas basin USGS has assessed. This is followed closely by the Greater Green River Basin in southwestern Wyoming, which has 84 TCF of undiscovered natural gas, of which 82 TCF is continuous (tight gas).
“Understanding our domestic oil and gas resource potential is important, which is why we assess emerging plays like the Utica, as well as areas that have been in production for some time” said Brenda Pierce, USGS Energy Resources Program Coordinator. “Publicly available information about undiscovered oil and gas resources can aid policy makers and resource managers, and inform the debate about resource development.”
The Utica Shale assessment covered areas in Maryland, New York, Ohio, Pennsylvania, Virginia, and West Virginia.
Some shale rock formations, like the Utica and Marcellus, can be source rocks – those formations from which hydrocarbons, such as oil and gas, originate. Conventional oil and gas resources gradually migrate away from the source rock into other formations and traps, whereas continuous resources, such as shale oil and shale gas, remain trapped within the original source rock.
These new estimates are for technically recoverable oil and gas resources, which are those quantities of oil and gas producible using currently available technology and industry practices, regardless of economic or accessibility considerations.
This USGS assessment is an estimate of continuous oil, gas, and natural gas liquid accumulations in the Upper Ordovician Utica Shale of the Appalachian Basin. The estimate of undiscovered oil ranges from 590 million barrels to 1.39 billion barrels (95 percent to 5 percent probability, respectively), natural gas ranges from 21 to 61 TCF (95 percent to 5 percent probability, respectively), and the estimate of natural gas liquids ranges from 4 to 16 million barrels (95 percent to 5 percent probability, respectively).
USGS is the only provider of publicly available estimates of undiscovered technically recoverable oil and gas resources of onshore lands and offshore state waters. The USGS Utica Shale assessment was undertaken as part of a nationwide project assessing domestic petroleum basins using standardized methodology and protocol.

Cummins Westport Begins Developing New Gas Engine, Canada
Cummins Westport announced it has begun development on the ISB6.7 G, a mid-range 6.7 liter natural gas engine designed to meet the increasing demand for on-highway vehicles powered by lower cost, cleaner and increasingly abundant natural gas. As a leading supplier of natural gas engines, Cummins Westport Inc. continues to expand its product range to supply the growing demand for natural gas engines.
The ISB6.7 G engine will be based on the Cummins ISB6.7 diesel engine and will use Cummins Westport’s proven spark-ignited, stoichiometric cooled exhaust gas recirculation (SEGR) technology. Exhaust aftertreatment will be provided by a simple, maintenance-free three-way catalyst.
The engine will run on compressed natural gas (CNG), however, the natural gas may be stored on the vehicle in liquefied natural gas (LNG) state or as CNG. The ISB6.7 G is expected to be in production by 2015 and will be designed to meet Environmental Protection Agency (EPA) and California Air Resources Board (CARB) regulations in force at the time of launch.
“The addition of the ISB6.7 G will round out our family of high performance natural gas engines,” said Jim Arthurs, President of Cummins Westport. “It joins the 8.9-liter ISL G, with over 16,000 engines in service, and the 11.9-litre ISX12 G, which will start production in 2013, to give our customers a broad range of natural gas engines for on-highway applications.”
