The Horse Hill-1 (HH-1) well has flowed light, sweet crude at an average rate of 168 barrels per day (bbl/d), Solo Oil said in a news release.

The well flowed the 37 degree API oil via rod pumping over a continuous 9-hour period, Solo said. The news was delivered to Solo by Horse Hill Development Ltd., the operator.The flow is from a 103-foot aggregate perforated zone within the Upper Portland sandstone interval at a depth of about 615 meters.

Maximum flow during this test period was restricted by the initial rod pump configuration, Solo said. The flow test will now continue with a pump configuration designed to permit optimal flow rate over a longer period.

“The Horse Hill well continues to show excellent results from all levels having previously tested at rates up to 900 barrels oil per day from Kimmeridge limestones,” Solo Chairman Neil Ritson said in the release. “The nearby Brockham Field has been producing commercially for many years from the Portland sandstone at rates up to 140 bbl/d and consequently we look forward to the successful completion of the tests at HH-1, which we feel confident will demonstrate commercial production potential.”

Solo owns a 6.5% interest in the Horse Hill well which is located on the north side of the UK Weald Basin close to Gatwick airport in PEDL137, the release said.
