Commissioning of Saltfleetby BO7T Well Permanent Flowline

Angus Energy (AIM: ANGS) is pleased to announce that the permanent flowline from the BO7T well at the Saltfleetby gas field in Lincolnshire was successfully commissioned on Friday 3^rd November at 16.30 with minimum production loss. This has been a challenging project not least because of the weather conditions during construction but also because of the technical challenges in finalising the flowline design.

Operations Director Tim Kaye commented "This is another key Company milestone delivered safely and with no harm to the environment and we can all take pride in another site goal achieved with the material benefit of reducing costs at site and further improving the long-term sustainability of the Saltfleetby Field".

CEO Richard Herbert added "Since the BO7T well came on stream in May, it has been operating in a temporary separator and flowline configuration, which has added complexity and costs to the operations at the field. The period of well clean up was much longer than we had expected, due to incomplete acidization of the mud additives used to control the wellbore during the drilling of the reservoir section. Now that fines production has reduced and with the completion of the engineering works to install the permanent flowline, we are seeing stable well performance and will have a significant reduction in operating costs with the removal of expensive rented equipment and personnel required for the temporary flowline. I am very grateful to the operations team at Saltfleetby for their excellent work to complete this significant project for the Company".
