Siccar Point Energy has successfully concluded well testing operations on the 204/10a-5 appraisal well in the Cambo field, north-west of Shetland.
A vertical pilot hole was initially drilled confirming over 100ft of oil column and a higher than anticipated net pay of 58ft, Siccar informed on Thursday.
Furthermore, the company said that extensive logging and coring were conducted confirming a high-quality multi-Darcy reservoir with 23 API oil and petrophysical properties better than anticipated.
A 1612ft horizontal section was then drilled to conduct an extended well test. Following initial well clean-up operations, the well was successfully tested on natural flow for 10 days. A full evaluation of the test results will take place over the coming weeks as further pressure build-up data are obtained remotely after the rig’s departure.
Initial results ‘encouraging’
According to Siccar, initial results are encouraging indicating excellent reservoir productivity and sustained flow. The results of the well will now be incorporated into the Cambo field development plan and the well suspended for use as a future development well.
Earlier in the year Shell acquired a 30% non-operated working interest in UKCS licenses P1028 and P1189 (incorporating the Cambo discovery) and a 22.5% non-operated working interest in P1830 (including the Blackrock prospect).
An exploration well is also planned on the nearby Blackrock prospect in 2019.
On May 23, 2018, Siccar Point Energy and Shell secured additional strategic acreage in the Oil & Gas Authority’s 30th Licensing Round expanding their acreage position in the Greater Cambo Area. This new license area includes the Tornado gas discovery, as well as multiple exploration prospects, and provides satellite development opportunities to the Cambo field development.
Jonathan Roger, CEO of Siccar Point, said: “We are delighted that the well test has further improved our understanding of the Cambo field and we will now be focussing on progressing the development plan of this major asset with our partner Shell.”
