Reabold, the investor in upstream oil and gas projects, is pleased to announce an update in respect of the West Newton A-1, A-2 and B-1z discovery wells as part of the Extended Well Test ("EWT") programme, accompanied by an updated estimate of in-place oil and gas volumetrics of the Kirkham Abbey reservoir in the Greater West Newton area of PEDL183.
Highlights
As part of the EWT the wells recovered good quality gas to surface
- Methane content +/- 90%, Ethane +/- 4.5% with heavier ends present
- Good correlation of gas samples between WNA-1 , WNA-2 (awaiting further analysis) and WNB-1z
Liquid hydrocarbons recovered to surface
- WNA-1 : sample analysis of oil shows, 41 degree API
- WNA-2 : oil/condensate recovered to surface, specific gravity (SG) 0.804, 44 degree API, analysis pending
- WNB-1z: liquid hydrocarbons recovered to surface, fingerprint shows similarities to WNA-1 analysis
Thick Kirkham Abbey reservoir development
- WNA-1 - 75 metres Measured Depth ("MD")
- WNA-2 - 66.5 metres MD
- WNB-1z - 68 metres MD
The results of the EWT have confirmed that the WNA-1 , WNA-2 and WNB-1z wells are substantial hydrocarbon discoveries.
Gas and light oil/condensate were recovered to surface from the WNA-2 and WNB-1z wells, although sustained flow rates were not achieved, and multiple samples have been gathered for geochemical analysis which is currently underway.
The large suite of data accumulated during the EWT`s including downhole logs, pressure data, geochemical and core analysis will be used to progress a reservoir modelling study to determine the optimum production design for the Kirkham Abbey reservoir.
Over the coming weeks, a number of external studies, utilising the knowledge of specialist carbonate reservoir modelling energy consultants will be conducted, encompassing a wide range of potential reservoir stimulation treatments, the results of which could be applied to the West Newton series of wells, in order to achieve optimum flow rates.
The "Greater West Newton" area has been confirmed to contain material resources. The method by which to produce this known accumulation of hydrocarbons is still being assessed.
This data will be used to inform the drilling of the next well on the West Newton field, which will be designed to deliver an optimal flow rate from the Kirkham Abbey formation.
Revised Volumetric Assessment
The operator, Rathlin Energy (UK) Limited , has conducted a review of the Most Likely Median Case estimated in-place hydrocarbons within the Kirkham Abbey formation, over West Newton discovery and several other material undrilled exploration prospects on trend with West Newton, within the 176,000 acre licence area including the Ellerby, Spring Hills and Withernsea prospects.
Sachin Oza, co-CEO of Reabold, commented:
"We are very pleased that the test programme has confirmed significant discoveries at West Newton at both the A and B sites, particularly via the recovery of both natural gas and hydrocarbon liquids to surface. The test programme has provided us with an abundance of data which will now be used to establish the optimum drilling and completion techniques for oil and gas production at West Newton. The B1-Z and A-2 wells are available for stimulation to achieve near term flow, and we already have permissions in place to drill the next well on the field.
"Reabold remains in a robust funding position, and we look forward to providing further updates as the project progresses."
