The Reti Well No. 01-A was drilled down to its Target Depth of 770 meters. Based on electric logs, geological and drilling data, the production testing commenced on August 1, 2009. The objective of the test was to evaluate the potential of Pirkoh Limestone of middle Eocene age.

Three zones in the Pirkoh limestone have been selected for testing. Zone-I in the interval (641 - 634 = 07 M) proved to be tight and
water bearing, while Zone-II, (616 – 598 =18M) on 36/34" choke size has produced 2.82 MMSCFD/D of gas with a wellhead flowing
pressure of 498 Psi. The short duration preliminary testing results are as under:

Choke Size WHFP (PSI) Quantity of Gas (MMSCFD) Quantity of Condensate (BPD) Quantity of Water (BPD)
32/64" 498 2.82 Nil 0.6
