DNO Heather Limited reports that production from the Heather Field in Block 2/5 of the Northern North Sea has been nearly doubled to 8,500 barrels of oil per day and that the field is now producing at a rate last recorded in 1993.

The increase in production is as a result of bringing infill well H-61z on stream. The well, which was designed to develop un-tapped oil in fault blocks on the northern edge of the field, was brought onto production at an initial rate of about 4.500 barrels of oil per day and a tubing head pressure of 1,700 psi. In addition to the production generated, the well is providing enough gas at around 650 standard cubic feet per barrel produced to allow gas importation to the platform to be suspended.

Confirming the recent drilling success Dr Stewart Watson (Chief Executive) commented that “DNO’s objectives have been to refine the description of the Heather reservoir, which is known to be complex, and to deploy modern well construction techniques to raise production and increase recovery from the field. Well H-61z was side-tracked from a previously suspended well (H-58z) and reached a total depth of 15,500 feet. The Heather reservoir is only 250 feet thick but the well was steered sub-horizontally through three fault blocks and penetrated a total of 2,300 feet of gross reservoir.

Although it is expected that production from the well will decline over the next few weeks, the results demonstrate that with commitment and expertise the mature fields of the Northern North Sea have still much oil to deliver.”
