Solo Oil Plc announced on 9 March 2018 that it has completed the acquisition of an additional 5% interest in Horse Hill Developments Limited (HHDL). Solo has acquired the 5% interest in the company in return for a cash consideration of GBP 650,000. Solo now holds a 15% stake in HHDL which is the equivalent of 9.75% interest in Horse Hill licences PEDL 137 and PEDL 246 which contain the Horse Hill Discovery. Testing of the discovery is scheduled to commence in Q2 2018 which it is hoped will determine the commerciality of the Portland sandstone reservoir. Additional testing of the Kimmeridge fractured Limestone section will also be carried out. The testing process is expected to last approximately 150 days. The Horse Hill-1 discovery was flow tested during Q1 2016. Operations commenced on 8 February 2016. On 16 February 2016 Solo announced that light 40Â° API oil has flowed to surface from an 80 ft zone within the Lower Kimmeridge Limestone at a depth of 900 m. Initial 700 bo/d flowed through a 1â choke with a mix of 50:50 water and oil. A 32/64â choke was used resulting in a steady flow of 460 bo/d with a 99% oil to 1% water mix. The following day Solo confirmed that production has continued at a stable rate of 450 bo/d through a smaller 28/64â choke. The company then moved to test the Upper Kimmeridge Limestone. On 1 March 2016 Solo reported that water-free 40Â° API, light, sweet oil has flowed naturally to surface at a stabilised rate of 900 bo/d. The production test was undertaken over 88 ft perforated zone at approximately 840 m depth. Initially the flow was restricted using a 1â choke and commenced with a rod pump with an initial flow of 700 bo/d before the pump was stopped and natural flow increased to 900 bo/d. The following day it was reported that oil flow continued at an average rate of 838 bo/d. On 9 March 2016 partner Solo reported on the testing of the shallower Portland Sandstone. The well tested 37Â° API and flowed to surface via rod pumping at a stabilised rate of 168 bo/d over a nine hour period from a 31 m aggregate perforated zone at a depth of 615 m. On 21 March 2016 Solo announced that testing continued on this section using the same pump, located immediately above the perforated zone and resulted in stable flow over a two day period. A larger stroke pump was installed resulting in a maximum rate in excess of 360 bo/d over eight and a half hours.  Interest in the licences is held by Horse Hill Developments Limited (65% + operator) and Magellan Petroleum (UK) Limited (35%). Â
