Saltfleetby Update: Pipe Inspection and Summer Maintenance

Angus Energy (AIM: ANGS) has successfully assisted a fellow Operator in a planned pipe inspection operation last week.  This planned operation demanded the diversion of our export flow from Saltfleetby into a third party pipeline and involved two transmission grid entry points and two industrial customers on the Humber.

 The Company was fully reimbursed for this diverted flow, which averaged 9.3 mmscfd, at market prices.  Normal export into the transmission grid at Theddlethorpe seamlessly resumed during the Gas Day ending 5 a.m. on 10 June.

A summer maintenance shutdown is planned for 19^th to 21^st June inclusive.

Saltfleetby production can be seen on the National Gride webpage, as follows:

Important Notices

This announcement contains 'forward-looking statements' concerning the Company that are subject to risks and uncertainties. Generally, the words 'will', 'may', 'should', 'continue', 'believes', 'targets', 'plans', 'expects', 'aims', 'intends', 'anticipates' or similar expressions or negatives thereof identify forward-looking statements. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. Many of these risks and uncertainties relate to factors that are beyond the Company's ability to control or estimate precisely. The Company cannot give any assurance that such forward-looking statements will prove to have been correct. The reader is cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this announcement. The Company does not undertake any obligation to update or revise publicly any of the forward-looking statements set out herein, whether as a result of new information, future events or otherwise, except to the extent legally required.

Nothing contained herein shall be deemed to be a forecast, projection or estimate of the future financial performance of the Company.

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.
