Egdon Resources plc has completed the proppant squeeze operation on the Ashover Grit reservoir interval in the Wressle-1 oil well, North Lincolnshire.
The oil and gas joint venture project in licences PEDL180 and PEDL182 comprises the operator Egdon (30%), Union Jack Oil (40% economic interest) and Europa Oil & Gas (Holdings) plc (30%).
INSPECTION
A total of 146 cubic metres of gelled fluid with 17.3 tonnes of ceramic proppant were injected into the Ashover Grit formation in line with the authorised programme.
The injection operations lasted a total of one hour and 30 minutes over a two-day period.
Egdon said that there had been no induced seismicity during the work and that noise levels were well within the permitted limits.
The operation was subject to a pre-operational inspection by the Health and Safety Executive and active monitoring by the Environment Agency.
Ground and surface water monitoring has continued in accordance with the requirements of the environmental permit.
All equipment and personnel associated with the operation have now demobilised from site.
NEXT STEPS
Wressle-1 well will undergo a coiled tubing operation to clean the production tubing prior to bringing the well back into production through the permanently sited production facilities.
Egdon added that, based on the implemented programme, pre-operational simulation modelling concluded that the proppant squeeze operation would result in constrained flow rates of 500 barrels of oil per day (gross).
Once the well is brought back into production, Egdon will report on the stabilised flow rates achieved following the proppant squeeze and coiled tubing operations.
WRESSLE
The Wressle-1 well, which was drilled in 2014 and tested in 2015, has flowed oil and gas from three separate reservoirs, the Ashover Grit, the Wingfield Flags and the Penistone Flags.
This totalled 710 barrels of oil equivalent per day from all zones.
In September 2016 a competent person’s report made independent estimates of reserves and contingent and prospective oil and gas resources for the Wressle discovery of 2.15 million stock tank barrels classified as discovered (2P+2C).
