**[Union Jack Oil](https://www.directorstalkinterviews.com/company/union-jack-oil-plc/ujo.l)
plc** ([LON:UJO](https://www.directorstalkinterviews.com/company/union-jack-oil-plc/ujo.l)),
a UK focused onshore hydrocarbon production, development and exploration company
is pleased to offer an update on operations at the Wressle oilfield development,
located in North Lincolnshire, covered by the licences PEDL180 and PEDL182.

Union Jack Oil holds a 40% economic interest in this development.

The Company is pleased to advise that the proppant squeeze operation on the Ashover
Grit reservoir interval in the Wressle-1 well has been completed safely and successfully.
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.

No health, safety, environmental or security issues were experienced during the 
operations; and as predicted, real time monitoring confirmed there was no induced
seismicity and that the 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.

The Wressle-1 well will now be subject to a coiled tubing operation to fully clean
the production tubing prior to bringing the well back into production through the
permanently sited production facilities.

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, we will provide a further update 
to report on the stabilised flow rates achieved following the proppant squeeze and
coiled tubing operations.
