Angus Energy PLC (LON:ANGS) has confirmed production at the Brockham field near Reigate in the Weald Basin will re-start in March from two wells rather than the one originally planned.
Production will come from BR-X2Y and BR-X4Z and target the Portland Reservoir at a depth of about 615m.

BR-X2Y was producing about 30bbl/day prior to its temporary closure.
Previously Angus had said it wanted 150 barrels daily from Brockham, including a sidetrack to X4Z.
Production from both wells will be carried out through conventional production with no fracking.
