Avington Oil Production to Restart
UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that the Avington Joint Operating Committee has now formally agreed to restart oil production at the field. Prior to its 2017 shut-in, the field had produced 0.276 million barrels of an estimated mid case of 59 million barrels of original oil in place ("OIP"), a recovery factor of only 0.47%. As the three closest similar producing fields to Avington exhibit oil recoveries of around 6-13% of the assessed OIP, potentially significant remaining recoverable oil resources lie within Avington for future exploitation.
Avington operations will recommence via a workover of Avington-3z, the field's best performing well, which came on stream in 2007 and accounts for around 81% of produced oil. Given the 5-year shut-in period, which potentially has permitted reservoir pressure around the well to build up, some element of "flush" production (i.e., higher than the flow rate prior to shut-in) is expected upon production restart.
The field was granted new planning consent in December 2021. UKOG holds a 5% non-operated interest in Avington and the surrounding licence.

Glossary
| oil field | a subsurface oil accumulation existing within a single or multiple geological reservoir unit from which oil is recovered to surface. Note that an oil field can consist of one or more oil pools or distinct reservoirs. |
| oil in place | the quantity of oil that is estimated to exist in naturally occurring accumulations within the ground before any extraction to surface via production |
| recovery factor | the recoverable amount of oil in place, normally expressed as a percentage |
| recoverable resources | those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations, but the applied project(s) are not yet considered mature enough for commercial development |
| workover | the process of performing maintenance or remedial treatments on an oil or gas well. In many cases, workover implies the removal and replacement of the tubing string after the well has been killed and a workover rig has been placed on location. |
