Third Energy acquired its onshore assets in North Yorkshire through the purchase of Viking UK Gas Limited and RGS Energy Services in 2011. These assets are 100% owned and operated by Third Energy and include mature producing fields, undeveloped gas discoveries, pipelines and a gas gathering and power generation station, supplying power to the grid.

Over the twenty years of operations, all the operations and drilling/well works have been undertaken safely and with no adverse impact to the environment or communities. We will continue to have the same focus for future operations.

Third Energy has made significant investment in reappraising these fields and assessing the potential of other undeveloped gas discoveries in the area since acquiring the assets. This has included acquiring new data, 3D seismic, innovative high-resolution gravity surveys and detailed analysis of local and regional well data. There has also been major investment in improving production from the existing very mature producing fields, including drilling new production wells and well work-overs.  

Ebberston Moor & Ebberston Moor South

The PL-077 licence, held by Third Energy, lies across Ebberston Moor within the North York Moors National Park. The Ebberston Moor gas field (originally called Lockton) was discovered in 1966 and produced gas between May 1971 and 1974. Since the 1970s further discoveries of gas have been made in the area.

Third Energy is taking forward the Ebberston Moor South development, in a 50/50 joint venture with Moorland Energy Limited (MEL), the adjacent licence holder. The Ebbertson Moor South gas field straddles Third Energy’s PL-077 and MEL’s PEDL-120 licence blocks.

Gas produced from the existing Ebberston Moor South well will be transported via a new 14 kilometre pipeline to the Knapton Generating Station. To improve reservoir performance, the development will include an additional well for water production and re-injection.

The public consultation on the project was held in July 2014 and the Planning Application was submitted to both North York Moors National Park Authority and North Yorkshire County Council on 18 August 2014. Planning approval was given by both mineral planning authorities in 2015. Information relating to the project can be found here.

Vale of Pickering – Current Operations

Gas was first discovered in the Vale of Pickering in 1985.  Production from Third Energy’s four gas fields – called Kirby Misperton, Pickering, Malton and Marishes - began in 1995.  Third Energy produces gas from its six existing well pads. Gas production is primarily from the Permian age Kirkham Abbey Formation (KAF) and also from the deeper Namurian age reservoirs. 

The Vale of Pickering gas fields are mature and have experienced significant declines in production.  Third Energy is currently moving forward with projects to improve gas recovery, including the current planning application to convert the PK1 well at Pickering to a production and water injection well.

Knapton

The Knapton Generating Station (KGS), supplied by gas from our four producing gas fields beneath the Vale of Pickering, has been providing a source of power to North Yorkshire since May 1995.Power Generation FacilitiesThe General Electric CF6-80C2 aero-engine undergoing a routine service It is currently the largest generating station in the UK to use onshore produced gas. KGS has processed 30 billion cubic feet of gas, generating 2,000,000 MWh of electricity. The plant has an excellent safety and environmental record. 

Power Generation Facilities

The power generation facilities consist of RLM 6000 EGT generation package with a LM6000 gas turbine. This is an industrial version of General Electric's CF6-80C2 aero-engine which powers many Boeing 747, Boeing 767 and Airbus aircraft. 

KM8

reservoir in our North YorkshireThe well screened site at Kirby Misperton

Third Energy drilled the KM8 well, within its existing Kirby Misperton gas field, during 2013.   

Samples were taken at several different depths to assess the hydrocarbon potential. Analysis of the gas bearing zones in the deeper Bowland section concluded that they should be appraised further. To assess their commercial potential, hydraulic fracturing will be used to stimulate gas flow from these inter-bedded sandstone and shale sections. 

Proposed Hydraulic Fracturing at the KM8 Well

The planning application submitted to North Yorkshire County Council in 2015 for its proposed hydraulic fracturing operation was approved by the Planning Committee on 23 May 2016.  The Environment Agency issued the necessary permits for the proposed project in April 2016.  These include a bespoke mining waste operation permit, including a non-hazardous mining waste facility, a bespoke radioactive substances permit and a bespoke groundwater activity permit.
