Solo has been informed by the Operator, Horse Hill Developments Limited, that the Environment Agency has formally granted the permit necessary to carry out a flow test of the Horse Hill-1 oil discovery well. The HH-1 well, drilled at the end of 2014, is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin near Gatwick Airport. Solo has a net attributable interest of 6.5% in the Licence Area.
According to HHDL, the planned flow test is designed to test both the oil bearing Upper Portland sandstone reservoir and the Kimmeridge limestone reservoirs beneath the Portland. The test is designed to provide the necessary reservoir engineering data to enable an assessment of the commercial viability of the Portland sandstone oil discovery, where significant oil shows were encountered whilst drilling. The test will also provide a further 'proof of concept' for the Kimmeridge tight oil play, which has previously been shown to flow oil elsewhere in the same formations of the Weald Basin, at Balcombe, some 10 miles to the south.
