Extended Well Test ("EWT") Update
Horse Hill-1 ("HH-1") Portland and Kimmeridge Oil Discovery, Weald Basin, UK
Alba (AIM: ALBA), the diversified mineral exploration and development company, is pleased to announce that it has been informed by Horse Hill Developments Ltd ("HHDL" or the "Operator"), the operator of the Horse Hill-1 ("HH-1") Kimmeridge and Portland oil discovery located in licence PEDL137, that the Kimmeridge Limestone 3 ("KL3") EWT programme has recorded sustained light, sweet, 40-41° API crude oil flow continuously and naturally to surface over the past 50 hours at sustained rates significantly exceeding those recorded during the KL3 short flow test programme in 2016.
Alba holds an 11.765% beneficial interest in licence PEDL137 and adjoining licence PEDL246.
Alba is further advised by the Operator as follows:
• KL3 EWT flow sequence commenced ahead of planned KL4 test.
• KL3 flowed 40-41° API continuously and naturally to surface (i.e. without any pump) over a 50 hour initial planned oil flow period. Oil flow initiated instantaneously with minimal pressure "draw- down". First planned 24-hour shut-in and pressure build-up test ("PBU") now underway.
• Sustained continuous oil rates of between 563 and 771 barrels of oil per day ("bopd") on 36/64 and 38/64 inch choke, respectively, recorded over last 24 hours through test separator. Gas rates up to 186,000 cu ft per day measured through enclosed flare. Flow sustained at constant stable bottom hole pressure.
• Recorded sustained rates significantly exceed the 464 bopd over a short 7.5-hour total flow period reported in 2016.
• Initial well productivity index of between 1.4 to 2.5 bpd/psi is around twice that seen in 2016 KL3 test.
• To date four tankers of KL3 crude have been exported to Fawley refinery.
• Zero formation water produced. Metered associated water rates of 52 barrels per day ("bpd") decreasing to 14 bpd (i.e. 9% decreasing to 2%) in the past 24 hours. Produced water consists wholly of returned heavy completion brine. Well continues to "clean-up" with decreasing water content.
• Simultaneous pressure data recorded in overlying KL4 is indicative that KL3 and KL4 are one single connected oil pool with an implied minimum vertical extent of 358 ft.
• Further updates to be provided in due course following completion of the ongoing PBU test, further well clean-up, flow stabilisation, downhole oil sampling and further pressure build up tests.
• The KL4, which flowed at a reported rate of 901 bopd over a 4-hour period in 2016, will be flow tested after completion of the current KL3 EWT.
It should be noted that these are preliminary results achieved during the well "clean up" phase. Alba awaits from the Operator the final reservoir information in order to ascertain the sustained deliverability of the KL3 and KL4 reservoirs.
George Frangeskides, Alba's Executive Chairman, commented:
"Whilst these are early results from the KL3 EWT sequence, with the well still "cleaning-up", the rates achieved so far in the Kimmeridge limestones are highly encouraging. We look forward to the results of the remainder of the KL3 and KL4 test programme, and look forward also to learning of the Operator's go forward plans for the field development of the Portland sandstone and Kimmeridge limestone reservoirs at Horse Hill".

Glossary
discovery | 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 |
draw down | the difference between the average static reservoir pressure and the flowing bottomhole pressure |
extended well test | a well test, as per the permission granted by the Oil and Gas Authority, with an aggregate flow period duration over all zones of greater than 96 hours and up to 90 days maximum |
Flow test | 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 |
Productivity Index | A mathematical means of expressing the ability of a reservoir to deliver fluids to the wellbore. The PI is usually stated as the volume delivered per psi of drawdown at the sandface (bbl/d/psi). |
