Oilex Ltd says that Cambay-77H continues to recover water, light oil and gas on a steady flowing tubing head pressure (FTHP) of ~220 psi on a 24/64th inch choke. The relatively steady FTHP is interpreted to indicate that the well has reached its long term stable production curve. Subsequent to completion of all coiled tubing (CT) operations, Oilex now estimates that ~5,400 bbls of Operations (CT and Frac) water remains in the well and continues to be recovered at surface.
Analysis of flowback data for ~ 85 days has been completed by RISC, a specialist oil & gas consulting company, with reservoir engineering personnel experienced in the Canadian Montney tight/shale gas play. The Montney Formation is a major productive unit and possible analogue for the Y Zone reservoir of the Cambay Field due to its hybrid siltstone and shale content.
