Hydrocarbon Discovery – Exploratory Well Halini Deep-1, Karak Block, KPK/Punjab
Mari Petroleum Company Limited (MPCL) has made a significant crude oil discovery at exploratory well Halini Deep-1 in Karak Block. Halini Deep-1 was spud-in on February 18, 2015 and was drilled down to its revised target depth of 5,900 meters into Wargal Formation. Halini Deep-1 ranks among the deepest wells in Pakistan and is the deepest well ever drilled by MPCL. It is highlighted that the well was drilled with MPCL’s own 2500 HP Rig Mari-3.
Subsequent to drilling, based on wireline logs interpretation and its integration with G&G data, hydrocarbons bearing zones were identified and tested in Samana Suk Formation which flowed 756 BBL/D crude oil having API of 290 @600F and 0.61 MMSCFD gas at half inch choke size. Additionally the already discovered reservoirs at Halini X-1, namely Lockhart/Hangu/ Lumshiwal were also tested at Halini Deep-1. Hangu/Lumshiwal reservoirs flowed 1,125 BPD crude oil having API of 300 @600F and 1.09 MMSCFD gas at half inch choke size.
Subsequent to DST, the well has been completed in all the producing formations. The completion integrity test has been conducted successfully. During CIT the well flowed comingled flow of 1,425 BPD of oil with 1.18 MMSCFD of associated gas. Philosophy of early production facility has been designed and first oil is expected by May 15 May, 2016.
Halini Deep-1 is MPCL’s 3rd consecutive discovery in Karak Block. First crude oil discovery was made at Halini X-1 in 2011 and second discovery of crude oil, condensate and gas was made at Kalabagh-1A in 2015. Discovery at Halini Deep-1 has further augmented MPCL exploration success rate which is already the highest in the Country. This discovery will further enhance the Country’s and Company’s hydrocarbon reserve base and play a pivotal role in achieving the Company’s planned growth and expansion targets.
