Resource upgrade for Iris Hades discovery offshore mid-Norway
Contingent resources from OMV’s recent Iris Hades gas/condensate discovery in the Norwegian Sea have risen substantially following recent evaluation.
Partner Faroe Petroleum now estimates reserves in the 63-322 MMboe range and based on preliminary fluid analysis condensate makes up around 25% of the resource, the company added.
The partners have contracted the semi-sub Deepsea Bergen to drill an appraisal well on the structure during the first half of next year, pursuing upside south of the discovery well.
Faroe’s forward programme includes five further exploratory wells in the Norwegian sector. In September, the semi-sub Transocean Arctic is set to spud the (operated) Rungne well targeting around 70 MMboe.
The same rig will then drill the Brasse East well (12.5 MMboe) for the company in the North Sea – Faroe is looking to prove further reserves to boost its planned Brasse field development.
Towards year-end a well should spud on the Equinor-operated Pabow prospect in the Stord basin east of the Utsira High in the North Sea: here the main target is in the Lower Jurassic Statfjord Group, potentially around 70 MMboe.
Early next year Spirit Energy will likely spud the Cassidy exploration well back-to-back with production wells on the Oda field in the southern North Sea. Cassidy is in license PL405 north of Oda, with potential resources of around 50 MMboe within the same Jurassic Ula formation.
Last on the list is the Yoshi well in 2019 in PL 836 S in the Norwegian Sea, south-west of the Smørbukk South field, targeting roughly 30 MMboe in Jurassic Fangst Group reservoirs.
As for Faroe’s current Norwegian field development programs, development drilling started at Oda on the 15th July.
Three top-hole sections have been completed and drilling of the first of the three wells is under way – production is due to start in mid-2019.
At Ula, three infill wells will be drilled during 2019-20 based on results from a recent time lapse 3D seismic survey. These will include new injection wells to extend the Water Alternating Gas pattern for the Ula field, along with infill production targets.
Work on the Brasse development is progressing, the next main project being concept selection, including the reservoir drainage plan and the choice of the host facility for fluid processing and onwards transportation. Faroe anticipates securing field development sanction during the second half of 2019.
At Brage, close to Brasse, three new wells are performing as expected, and operator Wintershall has committed to an additional long reach development well into the Sognefjord reservoir, probably spudding later this year.
The partners have also identified other promising infill drilling prospects.
As for Equinor’s Njord Future Project in the Norwegian Sea, highlights of this year’s refurbishment program on the Njord A semi-submersible in western Norway include the installation of blisters to enhance stability on all four columns, and installation of column top extensions and deck boxes.
Truss work reinforcement continues. The Njord B FSO entered the dry dock in Haugesund last month and upgrade work has started.
At the end of this month, gas production is due to cease from Faroe’s Schooner and Ketch fields in the UK southern North Sea.
