SK Gas Field – Republic of Tajikistan

On April 26th 2014, Dravida Petroleum signed the landmark 15 year Joint Cooperation Agreement (JCA) for the Development and Production of the SK Gas Field with the State Unitary Enterprise – Naftugaz, Ministry of Energy and Water Resources, Republic of Tajikistan.

Tajikistan is the most beautiful and peaceful country to do business in the CIS region.
The “SK” Gas field is located in the prolific oil and gas sedimentary basin, Southern part of Tajikistan. The SK Gas field was discovered in 1951. The field lies in the Western part of Vashka valley, 132 km South of the Capital Dushanbe and 2 km to the East of Kolkhozabad town. The field is very near to the main Dushanbe-Dusty road and waterway. The produced gas was fed into the nearby Kolkhozabad-Kurgantyube 14” gas distribution pipeline. The gas production was stopped in the late 2007 due to decline in the production levels of the old wells. If the modern day techniques are employed on these wells, this field is a very good candidate for Rehabilitation and Production Enhancement Operations.
Based on Tracs Reserves Report, the remaining recoverable gas reserves of this field amounts to 42.5 BCF (Billion Cubic Feet) in the shallow horizons of Paleocene and there is a huge upside potential of more than 1.5 TCF (Trillion Cubic Feet) of gas reserves in the deeper Cretaceous and Jurassic horizons.
After studying the available technical data of this field, Dravida Petroleum has planned to carry out 3D Seismic Survey, Work-over old wells and install Wellhead Compression to start producing gas from the shallow horizons.
Wellhead Gas Compression Technology
The producing wells in the SK Gas Field were suspended only due to the water entry in the production tubing which doesn’t allow the gas to flow through the well bore thereby to the well head. As a well’s gas pressure declines, the gas velocity often is not enough to transport produced liquids upward through the production tubing. This is commonly referred to as “liquid loading.” By compressing the gas near the wellhead, the wellhead pressure is decreased, which increases the production rate and prevents liquid loading. Using a wellhead compressor can substantially extend the service life of the wells. Depending on reservoir and well characteristics, a gas well with a depletion compressor can continue to produce gas for up to 10 years or more.
Further development of deeper horizons is envisaged by deploying 2600HP-3000HP Drilling Rigs and increase the recoverable reserves thereby adding value to the asset.
Dravida Petroleum is committed to cater the gas demand of the Republic of Tajikistan.
