How does the following 73H data translate to 77H, given their comparability?

CAMBAY-73
Clean up and production testing of the Cambay-73 well recommenced in April 2012 and is continuing. This vertical well was originally drilled and completed in 2008 with a relatively small scale fracture stimulation (86 tonnes proppant versus 1,200 tonnes in the horizontal Cambay-76H well). The well has 10 metres of active perforations in the Y Zone, the same target reservoir in Cambay-76H with similar geological characteristics. Cambay-73 is located about 800 metres south west of Cambay-76H surface location.
Cumulative production of 1,448 barrels of condensate and 50.5 million cubic feet of gas has been recorded from Cambay-73 (since the first short duration test in 2008 to 20 June 2012) confirming a liquids-rich gas composition. The gas rate after 60 days (from the restart of the production test in April 2012) was approximately 380,000 cubic feet per day, with the average gas to liquids ratio being approximately 40 barrels per million cubic feet of gas. During the recent production test period, water production rates have declined significantly as the well has flowed back and a stable flow regime is now established. Wellhead pressure has also stabilised at approximately 600psi.
It is anticipated that the continuing Cambay-73 production test will provide increasingly robust data to support the modelling of the production potential of the Y zone reservoirs. By also incorporating the data obtained to date from Cambay-76H well, these models can be used to reflect the production performance of a horizontal, multi-stage fracture stimulated well.
