Saltfleetby Sidetrack and Quarterly Flow Rates Update

Initial Flow Rates - Sidetrack SF07V

Angus Energy (AIM: ANGS) is pleased to announce that well initial clean-up operations concluded early on the weekend since which time the sidetrack SF07V well testing programme has been progressing satisfactorily. 

The well flowed at 2.1 mmscfd shortly after start up and flow rates have increased over the last 60 hours to 4 mmscfd with a near constant 30 barg wellhead pressure.  The rate of increase has been linear and there is, as yet, no deviation in that rate of increase. 

By way of context, deliverability from pre-existing wells has averaged around 5.4 mmscfd during the quarter and our competent Persons Reports of March 2020 and October 2021 set a P90 target just shy of 10 mmscfd for the plateau rate of flow from all three wells.

Throughout this period we have seen the steady removal of residual drilling fluids from the well and expect the clean-up to take several days before we reach the final deliverability.

Connection to the plant for gas processing and export is planned directly after the clean-up and we expect to realise the combined flow rates of all three wells later in the month.

Quarterly Flow Rates - Existing Wells

Gas volumes produced and sold equalled 5.4 million Therms in aggregate for the months of January, February and March combined or 1.8 million Therms per month being in excess of hedge requirement.  This yields an average of 5.4 mmscfd for daily flow rate.

Average daily flow rates were highest in January but suffered somewhat from work on the second compressor during February and March. 

Peak achieved flow rates from the two wells remained at around 6.0 mmscfd throughout the period and pressure was stable to gently falling at around 30 barg in line with management expectations. 

Gas condensate (liquid) production averaged 120 bbl/day which continues to be somewhat higher than expected. 

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.
