Encore Oil (LON:EO.) (EO/, 125.5p, ? 5.46%) provided an update on the Cladhan appraisal well 210/30a-4 located in UK North Sea Block 210/30a. The appraisal well was drilled as a deviated well to a Total Measured Depth of 12,252 feet and encountered oil bearing Upper Jurassic sandstones in two separate reservoir intervals. No Oil Water Contact was observed. The Upper reservoir sequence had a gross True Vertical Thickness (TVT) of 18 feet and a net sand of 13 feet TVT. The sand has an average porosity of 16% and hydrocarbon saturation of 82%. Pressures suggest that this reservoir is in a separate pressure regime from the Lower reservoir. In the Lower reservoir sequence, the main reservoir in previous Cladhan wells, the well encountered a gross TVT of 256 feet and a net sand of 21 feet TVT. The sand has an average porosity of 16% and hydrocarbon saturation of 75%. Initial pressure data indicates that the lower sand is in pressure communication with, and is part of the original Cladhan discovery. The well has proven an Oil Down To of 10,447 feet True Vertical Depth Sub Sea (TVDSS), giving a minimum hydrocarbon column of over 1,200 feet. Upon completion of operations at well 210/30a-4, the Transocean Prospect semi-submersible rig will commence the first planned side-track, 210/30a-4z to evaluate the Upper Jurassic sandstones significantly down dip from the 210/30a-4 well in an attempt to define oil water contacts for both the upper and lower reservoir units, as well as investigating the potential for thickening of the upper unit. It is expected that this side-track will take approximately 20 - 25 days subject to weather or operational delays. EO has 16.6%, Sterling Resources Ltd (the operator) has 39.9%, Wintershall 33.5% and Dyas has 10%.
Aminex (LON:AEX) (AEX, 8.4p, ? 2.61%) announced that The Minister for Energy & Minerals of Tanzania has signed a Development Licence with the Company's Tanzanian subsidiary, Ndovu Resources Ltd., ('Ndovu') for the Kiliwani North Gas Field in Tanzania. The Development Licence represents an area carved out of the Nyuni East Songo-Songo Production Sharing Agreement ('Nyuni PSA') which includes the mapped area of the Kiliwani North gas field. The Kiliwani North-1 well flowed gas at a rate of 40 mmscfd under full production test conditions and has been independently estimated to contain 45…
