Further Update on Horse Hill-1 Flow Test
Horse Hill-1 Oil Discovery Flows at a rate of 900 barrels per day from second zone
Restricted flow of 100% dry oil, through a 1-inch choke, using a rod pump, commenced at around 1350 hrs GMT yesterday at an initial instantaneous rate in excess of 700 barrels per day ("bopd"). At circa 1430 hrs the well started flowing freely to surface, without pumping. The free flow rate increased to over 900 bopd at 1500 hrs. The flow of dry oil then stabilised from 1500 hrs to approximately 1800 hrs, at rates averaging in excess of 900 bopd.
Note that as a consequence of flow initialisation via rod pump, the initial natural flow rates stated above were further restricted by the rods within the 2 and 7/8-inch production tubing.
The well was shut in at approximately 1830 hrs yesterday. The well was opened and free 'natural' oil flow recommenced at 2234 hrs yesterday. The well was flowed to obtain a further stabilised flow period and reservoir engineering data. A further update will be provided once this new data is available.
With this stable Upper Kimmeridge limestone flow, the two Upper Kimmeridge and Lower Kimmeridge limestone intervals have now produced a combined average stable rate of over 1,360 bopd.
As previously announced, on completion of this Upper Kimmeridge test, operations will move to the shallower Portland sandstone zone at approximately 615 metres below ground level.

a discovery is a petroleum accumulation for which one or several exploratory wells have established through testing, sampling and/or logging the existence of a significant quantity of potentially moveable hydrocarbons
extended flow test
a flow test, as per the permission granted by the
a flow test or well test involves testing a well by flowing hydrocarbons to surface, typically through a test separator. Key measured parameters are oil and gas flow rates, downhole pressure and surface pressure. The overall objective is to identify the well's capacity to produce hydrocarbons at a commercial flow rate

a clastic sedimentary rock whose grains are predominantly sand-sized. The term is commonly used to imply consolidated sand or a rock made of predominantly quartz sand.
