Serica Energy has confirmed the spudding of the Columbus 23/16f-CDev1 development well in the UK Central North Sea. The well will be drilled to a total depth of 17,600ft and will include a 5,600ft horizontal section. The well is being drilled with the Maersk Resilient Heavy Duty Jack Up rig and is expected to take around 70 days.
The Columbus development area is 35km north east of the Shearwater production facilities and will be drained by a single producing well tied into the existing Arran to Shearwater pipeline. A recent Competent Person’s Report estimates the Columbus gross undeveloped 2P reserves to be in excess of 14 million barrels of oil equivalent (boe).
The well will be connected to the Arran pipeline later this year, through which Columbus production will be exported along with Arran Field production. Production is expected to commence in early Q4 2021, with average gross production forecast to be around 7,000 boe per day, of which over 70% is gas. Read more…
