PEDL234 - Broadford Bridge
The potential and further understanding of the KL oil play has been our prime focus over the past year. The Broadford Bridge-1 and 1z ("BB-1/1z") oil discovery, located in the Weald's largest single licence, the 300 km² PEDL234, 100% UKOG owned and operated by Kimmeridge Oil and Gas Limited ("KOGL"), delivered on most of its technical objectives, namely: "proof of concept" for the existence of a continuous oil deposit within the Kimmeridge section, the determination of the deposit's lateral extent and supporting evidence for a regionally extensive natural fracture system within Kimmeridge Limestones. Importantly, the fracture system was shown to deliver oil to surface without the need for reservoir stimulation utilising massive hydraulic fracturing ("fracking").
The BB-1/1z exploration well, for which operations ceased in March 2018, was a bold 27 km step-out from HH-1, designed to provide proof of our geological concept that oil within the KL, as demonstrated at the Company's Horse Hill-1 discovery ("HH-1"), was part of a regionally extensive continuous oil deposit. Since the two prior Weald Basin wells which tested and recovered Kimmeridge oil to surface, HH-1 and Balcombe-1, were drilled within well-defined mapped conventional structural features, it was necessary to demonstrate that the BB-1/1z location, without any discernible conventional hydrocarbon trapping configuration (i.e. no structural or stratigraphic closure) contained moveable oil within the Kimmeridge.
Consequently, the multiple live, mobile oil shows seen in cuttings and drilling fluids, light oil seen in open fractures in cores, the recovery of oil and gas to surface from KL1 to KL4 flow tests, together with the light oil flowed continuously to surface from the KL5 test zone, presents further compelling evidence that the Upper Jurassic Kimmeridge of the central Weald Basin contains an extensive continuous oil accumulation. We believe that the data provided from BB-1/1z and analysed to date provides us proof of geological concept.
These live, mobile oil occurrences, together with corresponding rock and electric log data likely demonstrate a KL oil deposit of up to 1400 ft vertical extent exists at BB-1z. Geochemical analyses further support this proof of concept, as all oil samples from both BB-1z and HH-1 analysed to date are determined by Geomark Research to come from the same Upper Jurassic shale source, i.e. the oil lies within or immediately adjacent to the Upper Jurassic rocks where it was generated, one of the fundamental characteristics of a continuous oil accumulation.
The flow test campaign also contributed significantly to our understanding of the Kimmeridge play. Flow test inflows and pressure data, together with the specialist analysis of formation image log and core fractures, also demonstrated that the Kimmeridge contains both a local and regionally developed natural-fracture system, key to t
