Australia-registered Oilex have reported reaching total depth on a tight oil play and finding a commercially viable hydrocarbon reserve.

$Cambay-77H is offset 300m from the Cambay-76H horizontal well that underwent a successful multiple staged fracture stimulation programme along its 633m lateral section in 2012.$

Oilex's offshore Indian play, Cambay-77H, has reached total depth at 2370m. The primary reservoir target (Y Zone) has been intersected on prognosis and increased gas readings similar to Cambay-76H indicate the reservoir is hydrocarbon bearing. A full suite of logs will be acquired subsequent to conditioning the wellbore, after which, the 4.5 inch production casing will be set and cemented in preparation for a fracture stimulation programme.

However, it was suspended before testing due to downhole mechanical problems. Prior to suspending the well, gas and condensate flowed to surface during well control operations.

A shorter lateral section (350m) in Cambay-77H coupled with a conventional “plug and perf” method for fracture stimulation is expected to facilitate the primary goal of the well – recording hydrocarbon flow information at surface during a production test.
