Further significant flows at Horse Hill-1
Further significant oil flows from the Horse Hill-1 well have been confirmed by Horse Hill Developments Limited.
Alba Mineral Resources, Doriemus, Evocutis, Stellar Resources, Solo Oil and UK Oil & Gas said they had been notified that light, 40-degree API, sweet oil has continued to flow naturally to surface from an 80-ft zone within the Lower Kimmeridge limestone interval at a depth of approximately 900 metres below ground level.
Flow re-commenced at around 7:45 a.m. yesterday at a steady oil rate in excess of 456 barrels of oil per day over a further 9.5-hour period using a smaller 28/64-inch choke in order to further stabilise the flow. Yesterday's flow consisted of dry oil with zero water.
As previously announced, phase 2 and phase 3 operations will move to the shallower Upper Kimmeridge limestone and Portland sandstone zones at approximately 840 and 615 metres below ground level, respectively, once the Lower Kimmeridge testing is completed.
The HH-1 discovery well, the original exploration drilling phase originally completed at the end of 2014, is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin near Gatwick Airport. Alba owns a 9.75% interest in PEDL137.
