Saltfleetby Field: Commissioning of B7T Well

Angus Energy (AIM: ANGS) is pleased to announce the commissioning of the recently drilled B7T sidetrack well at the Saltfleetby Field took place this morning. The well has been connected by a temporary flowline to the production facilities on the Saltfleetby site and processed gas is being delivered to the National Grid. At present the well is flowing at approximately 4 mmscfd with the B2 well at 2 mmscfd -  each well's flow rate being intentionally restricted in order to allow for co-production within the capacity of a single compressor.  The A4 well has been temporarily retired in order to facilitate the balancing of pressure and flow rates of the two other wells.

The field will be operated in this mode while the new well is monitored and production stabilises and it is planned to then move to dual compressor operations and reintroduce the A4 well into production on or shortly after the 10^th May. The A4 well had been producing over 2 mmscfd and the B2 well over 3 mmscfd during April to give average monthly production of 5.3 mmscfd and we look forward to reporting combined flow rates with all three wells and both compressors later in this month.

The use of a temporary flowline with additional separation permits the continued clean up of the well but avoiding wasteful gas flaring. The performance of the B7T well is expected to continue to improve with production. Construction of a permanent flowline will commence this month, with anticipated completion in late-summer.

With production now approaching a stable plateau, Angus management is now able to deploy time and resources to monetising its other oil assets, developing a long-term transition storage capability at Saltfleetby, progressing its geothermal programme and exploring other strategic opportunities.

END.

Explanation of Terminology:

scm (standard cubic metre) mscm (thousand standard cubic metre) and mmscf (million standard cubic feet) are traditional measures of volumes of gas.  As producers we tend to observe volume flow from wells and through process plant but we are paid on the energy content which is metered and analysed at point of sale. Mmscfd represents mmscfd per day.

These two types of measurement, energy and volume, are related by the calorific or higher heating value which is the number of MJ per standard cubic metre.  Very intense processing, i.e. lower temperatures, will tend to remove more higher hydrocarbon fractions such as propane, butane and pentane, which will lower the calorific value but improve the margin of safety in terms of meeting transmission grid specification.

55,000 Therms, given a calorific value of about 41MJ per standard cubic metres is approximately equal to 5mmscf or 141,584 scm, 1,612,486 kwhrs, 5,804,948 MJ.
