DST conducted to test potential of Samanasuk & Shinawari, Lockhart formations: POL

August 25, 2022 (MLN): Pakistan Oilfields Limited (PSX: POL) on Thursday revealed that the Drill Stem Test (DST) was conducted to test the potential of Samanasuk & Shinawari and Lockhart formations at the well Tolanj West-02.

As a result, the potential of Samanasuk & Shinawari is 2.25 MMscf of gas per day, with no water at 32/64" fixed choke size at the flowing wellhead pressure of 374 psi.

Meanwhile, Lockhart’s potential came out during the test as 2.25 MMscf of gas per day, 34 barrels per day of condensate, and no water at 32/64" fixed choke size at the flowing wellhead pressure of 1,285 psi.

It is pertinent to mention that the above-referred formations were not hydrocarbon-bearing in the previous well drilled in the Tolanj West field.

Production from the well is expected to start in December 2022 and actual production figures may differ significantly based on the completion strategy that would be finalized considering all technical aspects.

To recall, POL informed on August 16, 2022, that hydrocarbons have been encountered in the development well Tolanj West-02 in partner-operated TAL block, which had been drilled and was under testing phase.

For the unversed, DST is a procedure for isolating and testing the surrounding geological formations through the drill stem. The test is a measurement of pressure behavior at the drill stem and is a way to obtain important fluid sampling information and establish the probability of commercial production. Accordingly, it should be borne in mind that the actual product may differ significantly from the test results.

TAL block is operated by MOL with joint venture partners including POL. The pre-commerciality working interest of Pakistan Oilfields Limited is 25%.
