Wellsite Compression in Pakistan

The Bhit Compression Project is a robust response to the natural depletion of the Bhit gas reservoir north of Karachi in Pakistan, designed to maximise productivity as the gas pressure reduces.

Challenges

Wellhead compression

for 10 mountain top wellheads

Flexibility of operation

Remote location

 

A concept study was carried out to consider the possible options to provide a solution. The selection was made based on the following criteria:

  •  Favourable economics, due to increased total gas recovery.  
  • Significant safety advantage, identified by HAZID review (comparing diverse operations to the common facilities proposed in other options).
  • The possibility of phased, time managed installation according to individual wellhead requirements. 
  • High reliability, demonstrated to have minimal impact on the overall reliability of the facilities.
  • Maximum flexibility of wellhead operations.
  • The option to decommission individual compressors as wells become redundant. 
  • Increased potential for re-use of the compressors at new well sites.

The design choice selected involved wellhead compression. Following the concept phase detailed design, procurement and construction were carried out to install 4 x 3.3MW and 6 x 1.9MW Ariel Reciprocating Compressors plus Caterpillar Gas Engines.
