Cambay-77H Well Reaches TD

Source: www.gulfoilandgas.com 4/15/2014, Location: Asia

Oilex Ltd is pleased to announce that Cambay-77H has reached TD at 2370m MD. 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˝ inch production casing will be set and cemented in preparation for a fracture stimulation programme.

In addition to drilling to TD, subsequent to the announcement on 8th April 2014, drilling operations have:
- Modified and tested the BOP for the 8 ˝ inch hole
- Changed the drilling assembly to suit the 8 ˝ inch hole size
- Weighted up the mud system for anticipated over-pressure in the reservoir
- Drilled out excess cement and retrieved some debris
- Drilled out of the 9 5/8 inch casing and conducted a formation integrity test (FIT)
- Directionally drilled into the Y zone reservoir section

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. 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.
