The 14/19-1 well on the Liz prospect reached a total depth of 12,031 feet (3,667 meters) and final logging was completed. The well is now being plugged and abandoned as a gas discovery. Initial log interpretations indicate that 56 feet (17 meters) of net hydrocarbon pay were encountered between 9,715 and 9,944 feet (2,961 and 3,031 meters) with a zone of over-pressured, predominantly sandstone reservoir. A hydrocarbon sample and formation pressures were recovered from this interval as well, but initial analysis suggests that the hydrocarbon type is wet gas. Dry gas was also recovered from a deeper interval below 11,155 feet (3,400 meters) indicating that gas pay is present in a poor quality reservoir, but it is uncertain what the rock type is and further analysis is required to assess the potential of the reservoir. The Liz fan was encountered between 8,333 and 8,425 feet (2,540 and 2,568 meters), and good oil shows were recorded while drilling, but logging and sampling confirmed the reservoir is tight. Weak oil was also noted in zones between 8,878 and 9,619 feet (2,706 and 2,932 meters), however due to increasing overpressure concerns, the well did not reach the deepest play type. The Liz prospect is located on the western margin of the North Falkland Basin on Tranche C offshore the Falkland Islands. Desire Petroleum serves as the operator of Liz, holding a 92.5% interest; Rockhopper holds a 7.4% interest. The well was drilled by Diamond Offshore's Ocean Guardian.
