This gives us confidence that we are well on track with progressing the state program of gas commercialization and monetisation in Uzbekistan.”
Well 209 was put into operation in the Kashkadarya region in the Alan field of the Mubarek Oil and Gas Production Department, which was subsequently connected to an existing gas gathering point, and construction of a 458 m long gas pipeline with a diameter of 168 × 6 mm was completed. The well flow rate is 102.6 thousand m3/d.
In the Bukhara region wells Nos 89 and 90 were put into commercial operation at the Dayakhatyn field of the Gazli oil and gas production department. The flow rates of the wells are 146.7 thousand m3/d and 34.1 thousand m3/d respectively. Gas pipelines with a diameter of 108 × 8 mm and a total length of 1036 m were built at the site.
At the Kulbeshkak field, well 54 was also commissioned where hydrochloric acid treatment (SCT) was additionally carried out to increase the gas flow. As a result of well stimulation, a commercial gas flow was secured with a flow rate of 233.1 thousand m3/d, together with completion of a 1681 m long gas pipeline with a diameter of 108 × 8mm.
