DESIRE’S NINKY WELL TO BE PLUGGED AND ABANDONED
By J. Brock (FINN)
Desire’s Ninky, 14/15-3 well, is to be plugged and abandoned with oil shows.
Desire Petroleum plc (AIM:DES), the company wholly focussed on the North Falkland Basin, advises that the 14/15-3 well on the Ninky prospect has reached a total depth of 2,620 metres in the Barremian source rock interval.
Based on drilling and wireline logging, the well encountered two sand-prone sections in the Upper and Middle F2 intervals, which were the primary targets (2323 metres to 2334 metres and 2365 metres to 2389 metres). The sands have a combined gross thickness of 35 metres and oil shows were encountered throughout both intervals while drilling. The reservoir quality is generally poor having only 5.6 metres of net reservoir with an average porosity of 13%. A thin interval of around 1.2 metres at the top of the Middle F2 zone is interpreted to be oil bearing from log analysis.
The Company said that wireline formation pressure measurements were attempted, but no valid pressures were obtained, indicating that the reservoirs are low permeability at this location. Desire’s statement went on to say that as a result no wireline sampling was attempted. The depositional model suggests these sands are sourced from the east and therefore better reservoir quality may be expected downdip. In addition, there are indications from seismic of further sands along strike on the Ninky structural high, which were not penetrated in this well. These opportunities will be evaluated with the new 3D seismic as part of Desire's prospect inventory update.
