Our share of production from these four wells alone totals 156 boepd,and as a result we expect our next CPR, due in Q1 2014, to report another majorincrease in Magnolia's daily production which, as at 1 August 2013, stood at214 boepd. "As with all wells, production will naturally decline from these reportedlevels before stabilising at lower rates. Such high initial production rateshowever are hugely beneficial to our strategy, as it results in the swiftrecovery of costs and allows revenues to be reinvested into new wells to proveup the reserves on our leases covering over 13,500 net mineral acres. With afurther 47 wells under development including those in which Magnolia has largerworking interests, we expect the excellent growth seen to date in our proven(P1) reserves, which as at 1 August 2013 was assigned a value of US$40.721m, tocontinue." ** ENDS ** Glossary `boe' means barrels of oil equivalent: a unit of energy based on theapproximate energy released by burning one barrel (42 US gallons or 158.9873litres) of crude oil.
