Our Work In Barton Moss
Our project at Barton
In June 2010, our planning application to explore for and extract hydrocarbons at the Barton site in Irlam, within PEDL 193, was approved by Salford City Council following a detailed planning process.
The process involved undertaking detailed consultation with the local community as well as satisfying the Council and planning officers that we are a safe and transparent operator and able to conduct our work in an environmentally respectful manner.
The site is located immediately east of the M62 and north of Barton Moss Road, Salford. The site covers an area of 1.8 acres – approximately the size of a football pitch.
The land to the north of the site (east of the motorway) comprises improved grassland; the land to the south and east of the site is arable farmland. Approximately 250m to the south lies the boundary of City Airport (Barton Aerodrome), with the A57 (Liverpool Road) and the Manchester Ship Canal beyond.
Barton Moss Exploration Well Results
The Barton Moss well was drilled as an exploration well in PEDL 193 in the North West of England, with the original key objectives of fulfilling the 13th Licence Round commitment obligation, assessing the CBM potential of the area and delineating the deeper Dinantian limestone horizon to better calibrate the pre-existing seismic interpretation which has confirmed our interpretation of the basin and so informed our 14th onshore licensing application accordingly.
The well, which was completed in March 2014, was successful in achieving all of these objectives and the results have helped refine our geological models and are consistent with our overall basin depositional model. The well encountered 15 gas bearing coal seams in accordance with the pre-drill prognosis. The well also encountered a Namurian Shale section, consisting of the Sabden Shale and the Upper and Lower Bowland Shales. Approximately 400 feet of core was recovered, including from the shale section.
The key results from the Barton Moss well cores, analysed by Weatherford in Colorado, are as follows:
- Total Organic Carbon (“TOC”) analysis indicates values of up to 5.72% with an average of ca. 1.9%
- The thermal maturity measurements of the shale places the shale in the gas generating window as per the basin model predictions
- The measured permeabilities are comparatively high for the observed porosities when compared with other typical US shale plays
- The mineralogy of the Bowland Shales in this area are very comparable with other key US plays, notably the Marcellus and Fayetville, when comparing quartz/clay/carbonate content
- The cores were observed to have numerous natural fractures with some evidence of alteration due to fluid migration. This is believed to be associated with the depositional setting of the well location.
In summary, the results from the Barton Moss well represent an important datapoint in understanding the structural and depositional setting of the basin. The results will help refine the subsequent appraisal programme as well as better delineate the resource potential. The extensive core and log analysis undertaken to date will be invaluable in defining future development options including geomechanical data for the design of hydraulic fracture treatments.
These results combined with the earlier Ince Marshes-1 well which encountered a thick (ca 1000 feet) section of shale with good TOC’s and the Ellesmere Port exploration well drilled in Q4 2014 will help to better define the overall potential of the IGas acreage in the North West.
