Rachel North Exploration Well 14/15-2
Oil Discovery (http://www.desireplc.co.uk/investor_relations_announcements.php?article_id=18 3)
Preliminary data collected indicate that this well is an oil discovery. The company has run an initial suite of wireline logs and this together with the drilling data indicate that the well encountered a 349 metres gross interval from 2621 metres to 2970 metres of sands and shales with hydrocarbons ,of which 57 metres is net pay in multiple zones. The thickest zone is 8 metres thick with an average porosity of 20% . Other zones are thinly bedded and lower porosity but require further analysis from additional wireline logs to establish reservoir potential.

Rachel North Well 14/15-2 Drilling Update (http://www.desireplc.co.uk/investor_relations_announcements.php?article_id=18 4)
Desire Petroleum plc (AIM: DES) the oil and gas company wholly focussed on the North Falkland Basin, today provides the following update on the latest logging results from the 14/15-2 Rachel North well which, following additional wireline data, will be plugged and abandoned with oil shows .
The results from the new logging data can be summarised as follows:
1. As announced on 3 December 2010 preliminary results from the interpretation of the initial log data indicated that the well had encountered a 349m gross interval of sands and shales with hydrocarbons, of which 57m was net pay in multiple zones.
2. However sampling of the main sand has shown that the hydrocarbons are residual and that the mobile fluid is water.
3. Analysis of the formation water recovered by sampling indicates much lower salinity than anticipated and when this value is incorporated into a revised log interpretation it is confirmed that the sands are water bearing. The salinity impacts the resistivity of the formation water (Rw) which is used to calculate the saturation of hydrocarbons in sands. Using industry standard procedures, the initial interpretation was based on a calculated Rw value from a clear water sand only 55m above the target sand, of the same stratigraphic age and depositional setting. This calculated value was consistent with measurements from other wells in the basin. Unexpectedly, the actual Rw value in the sample taken from the main sand turned out to be markedly different and the target sand is now interpreted to be water-bearing.
