Egdon has extensive operated and non-operated acreage  interests in the Gainsborough Trough unconventional gas plays in the East Midlands.

We are the third largest net acreage holder in the Gainsborough Trough play with 82,000 net acres and an estimated  20 TCF of net undiscovered Gas Initially In Place “pre-drill” (“GIIP”) in the shale and further tight gas potential.

This is shown on the map and chart below

2018 saw the commencement of unconventional exploration in the play at Tinker Lane which was drilled on the extremities of the play and failed to find the targeted Bowland shale in Q4. However the Tinker Lane well did encounter shales with a high gas content within the Millstone Grit sequence which may be positive for this play elsewhere in the Gainsborough Trough.

Egdon has a carried 14.5% interest in the second and third wells to be drilled in the basin at Springs Road operated by IGas Energy plc (follow Link to IGas Springs Road Project Site).

Springs Road-1 was spudded by IGas on 22 January 2019 and drilled to 3,500m after encountering all three pre-drill targets – the Bowland Shale, the Millstone Grit and the Arundian Shales. 

A hydrocarbon bearing shale sequence of over 250 metres was encountered within the upper and lower Bowland Shale (as announced on 11 March 2019). In addition, significant gas indications were observed within the Millstone Grit sequence, deeper parts of the lower Bowland Shale and the Arundian shale.

The cores and wireline logs underwent a suite of analysis, the first results of which were announced 27th June 2019. These will give us further insight into the resource potential and shale characterisation that will be utilised for future appraisal and development of the wider East Midlands area.

IGas acquired 147 metres of core within the Bowland Shale, the first extensive core sample from this basin, which has subsequently been analysed by Stratum Reservoir (formerly Weatherford Labs) in their laboratories in both the UK and the USA.

The results from core analysis are extremely positive and confirm that a significant hydrocarbon resource is present in the Gainsborough Trough.     

The key characteristics of the Bowland Shale in SR-01 compare favourably to commercial shale operations observed in North America such as the Permian and the Marcellus. The core results indicate a mature, organic rich source rock with good porosity confirming favourable gas resource density.  In particular, the low clay content is encouraging and an indication that hydraulic fracturing of the rock should be effective.

The analysis conducted will help delineate the resource potential and help refine the subsequent appraisal programme.  IGas, working with its joint venture partners, will now consider the attributes of the data set in order to commence planning for both the appraisal programme and pilot development within the Gainsborough Trough, including redefining the basin model.

We intend to make a further announcement and full technical presentation of the results, including comparison with analogous US shale plays in the third quarter of 2019.

The Springs Road drilling performance has been very encouraging with improved rates of penetration leading to better than anticipated drilling performance and lower costs.

Note: This analysis is based upon the Bowland Shale play only.  Encouraging results from the 2018 Tinker Lane well in the Millstone Grit sequence may render other more proximal licences prospective.

The results from core analysis are extremely positive and confirm that a significant hydrocarbon resource is present in the Gainsborough Trough.
