Stellar Resources plc has advised that the Horse Hill-1 well has now been drilled to the third casing point at 6612 feet measured depth (MD), and will now be electrically logged through the observed reservoir sections.
Electronic logging and full interpretation of these logs is expected to take approximately one week.
The depth of the third casing point was deepened from the previously announced 5900 ft to 6612 ft MD due to a number of reservoir targets being identified slightly deeper and thicker than expected.
On completion of the detailed logging, it is planned that a 9 5/8-inch casing will be set prior to drilling in an 8 ½-inch hole to a total depth (TD) of approximately 8680 feet MD in order to test for deeper Triassic aged formations where further electric logs will be acquired.
As previously announced, oil shows from mud logging have been identified in the Portland Sandstones and additionally oil shows, mineral fluorescence and elevated gas readings of C1 through to C5 have been detected whilst drilling the well to the current depth. The significance of these hydrocarbon shows will only become clear following the analysis of the detailed down-hole electric logs.
David Lenigas, company's Chairman, commented: "We await the results of the all-important electric logs from the Jurassic over the coming week and look forward to drilling the well to its TD to test the theory that hydrocarbons may be present in the Triassic."
