Statoil Petroleum AS has revealed that gas and oil reservoirs have been discovered at its Gina Krog Unit, both in the wildcat and the appraisal wells. Drilling north-east of the Gina Krog field and around 250km west of Stavanger, the company announced the latest findings for wildcat well 15/6-13 and both 15/6-13 A and 15/6-13 B appraisal wells.
Statoil Petroleum’s main objective for the drilling was to establish the volume of commercial petroleum in the wells. It drilled to the Middle Jurassic reservoir rocks to gather data on volume, continuity and properties. Whilst investigating 15/6-13, Statoil also attempted to acquire enough information to avoid later delineation; meanwhile, appraisal wells 15/6-13 A and 15/6-13 B were drilled to discover whether there were shallower gas and deeper oil reserves that might also be of commercial value.
Releasing the results for the wildcat well, Statoil Petroleum said there are two oil columns held within the sandstone. Oil/water contact was not encountered, and the reservoir is expected to have good properties within both the Sleipner formation’s upper part and the Hugin formation; meanwhile, it was discovered that appraisal well 15/6-13 A has seven and nine metres of oil within the sandstone, both of which are aquiferous. In well 15/6-13 B a gas column of around 60 metres was discovered, seven metres of which is in sandstone within the Hugin formation. Another 26 metres is in the Sleipner formation lying within sandstone.
Statoil Petroleum said the oil and gas columns total around 150 metres each; therefore, the overall total is about 300 metres. Initial calculations estimate that the discovery size could be up to two million standard cubic metres for the oil within the Hugin formation itself. Further analysis will be required to calculate just how much recoverable resources lay within the Sleipner formation.
At the three sites, wells were drilled to depths of 3,577 metres, 3,925 metres and 3,773 metres for 15/6-13, 15/6-13 A and 15/6-13 B respectively. All wells have now been plugged and abandoned as the Songa Trym drilling facility ‒ responsible for creating Statoil Petroleum’s wells ‒ moves onto another operation on the UK shelf. This next project is also funded by Statoil Petroleum.
For those working within the oil and gas industry, the latest finding of new reserves will be welcomed. It will take further analysis of the data to establish just how much oil and gas could be available for commercial retrieval.
