Horse Hill Oil Field Update - Commencement of HH-2Z Intervention
Alba Mineral Resources plc (AIM: ALBA), the diversified mineral exploration and development company, announces that it has received the following update from UK Oil & Gas Plc ("UKOG"), the majority owner of Horse Hill Developments Limited ("HHDL"), the operator of Horse Hill licences PEDL 137 and PEDL 246 in which Alba has an 11.765% interest:
- Operations to shut off formation water ingress into the Horse Hill-2z ("HH-2z") horizontal production well have commenced. By means of a Halliburton coiled tubing unit, production logging tools will be run along the entire length of the 2,500 ft horizontal section to identify the source of water ingress, thought to be from a series of open natural fractures at the base or "toe" of the wellbore.
- Once identified, the source of water ingress will be isolated, either via a rigid setting fluid plug, or by a conventional cementing and selective perforation programme. A resumption of HH-2z extended well test operations is planned to follow directly after a successful intervention. Portland oil pool test production from HH-1 will continue during the intervention.

Qualified Person's Statement
The technical information contained in this announcement has been reviewed and approved by Feroz Sultan (B.Sc (Hons) Geology, M.Sc, Petroleum and Structural Geology, Karachi and M.Sc Petroleum Geology, Imperial College London), a petroleum geologist with over 45 years' experience in the management, exploration, development and production of oil and gas.
Glossary
coiled tubing (CT) | a very long, narrow (typically 1 to 3.5 inch diameter) continuously welded metal tube, which is supplied spooled on a large reel. It is used for interventions to convey tools and/or fluids to specific downhole locations where deployment via wireline or other conventional means is impossible or impractical i.e. in existing deviated and horizontal wells. It can also be used for drilling purposes in existing wellbores via the installation of a drill bit and bottom hole assembly powered solely by drilling fluid circulation. Its use removes the need for a workover rig as most CT units are self-contained and trailer mounted.
|
horizontal well | a well that during drilling is steered so as to follow and remain within a particular geological stratum or reservoir unit having a trajectory that runs approximately parallel to the top and or base of the target horizon
|
oil field | an accumulation, pool or group of pools of oil in the subsurface that produces oil to surface
|
production logging tools (PLTs) | PLTs measure flowing fluid parameters on a zone-by-zone basis within a producing well. They provide diagnostic information, pinpoint where fluids such as water, oil and gas are entering a well and gives an indication about the efficiency of the perforations. PLTs normally measure four parameters: flow (via a series of spinners which rotate in the flow), density, temperature and pressure. The flow and density readings are used in traditional quantitative production logging analysis, whilst temperature and pressure data are used in more of a qualitative way to compute in-situ flow properties and locate zones of entry of fluids into a well
|
well test | or flow test involves testing a well by flowing hydrocarbons to surface, typically through a test separator over a flowing period of up to 96 hours; 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 and volumes. An extended well test or EWT is a well test with duration of over 96 hours and up to 90 or 180 flowing days aimed at assessing longer term production viability and the connected oil in place seen by the well. |
