Operational update

New corporate presentation

Cabot Energy (AIM: CAB), the AIM quoted oil and gas company focused on production led growth balanced with high impact exploration and appraisal opportunities, provides the following update on the Company's drilling operations in Canada.

16-05 side track well - well tested at significantly higher rates than forecast

§ The side track of the 16-05 well in the Rainbow area has been drilled, completed and is on production to the 13-36 facility through an existing pipeline

§ Following completion of the well, it was tested for a 24 hour period which saw near virgin reservoir pressure and natural flow:

- total oil produced during the 24 hour period, while restricted by a 9.5 millimetre (24/64 inch) choke, was 573 barrels of oil

- the well was producing at a rate of 680 barrels of oil per day ('bopd') by the end of the test period as the well flow cleaned up

§ The side track was drilled out from the original vertical well at a subsurface depth of 1,420 metres

- approximately 200 metres of the new deviated well bore intersected the targeted higher permeability section of the reservoir and was completed open hole to maximise reservoir productivity

§ The well is producing under natural flow and, following pump installation next week, is planned to be produced at a restricted rate of 200 to 225 bopd to best manage the longer term production potential of the reservoir

Remaining operations for 2017 - secondside track to be drilled and dual completion well to be brought online

§ The drilling rig used for the 16-05 side track will be moved to the next planned side track well once the ground has become sufficiently frozen to enable heavy traffic

- this is expected to occur by early December 2017 and the well brought into production before the year end, assuming successful operations

§ The regulatory approval process to inject water down the 13-33 well, which was dual completed as part of the summer work programme, is almost complete

- this is planned to be equipped and brought into production during November at a forecast 40 to 50 bopd

§ Planning for the 2018 winter work programme is advanced with up to four further side track locations being assessed for drilling in addition to a well workover campaign of up to ten candidates

The Company is on track to achieve its forecast exit production rate of 800 to 1,000 bopd, of which Cabot Energy owns 75 per cent.

Keith Bush, Chief Executive Officer of Cabot Energy, commented:

'The 16-05 side track result exceeded our expectations and strongly supports our technical view on the potential of the Canadian assets. The Company's existing Rainbow and Virgo acreage has many future side track candidates and high grading this inventory to provide low risk production growth at competitive investment metrics is the current priority.

'The subsurface and operational work undertaken during 2017 has greatly advanced our understanding of the Canadian assets and the true potential of the position, and we look forward to creating further low cost production growth via our 2018 winter work programme.'

A new corporate presentation will be made available on the Company's website later today.
