The Project will be funded by Asian Development Bank (ADB) with cofinancing from the Asian Infrastructure Investment Bank (AIIB) at an estimated total cost of $447.6 million. 2. Component 1 of the Project will involve the installation of wellhead compressors at Location – A of Titas Gas Field. The Executing Agency (EA) for Component 1 is Bangladesh Gas Fields Company Limited (BGFCL), which is one of the operating companies of the Bangladesh Oil, Gas and Mineral Corporation (Petrobangla) under the Energy and Mineral Resources Division (EMRD) of the Ministry of Power, Energy and Mineral Resources (MPEMR). BGFCL is entrusted with the production of natural gas from its five producing fields and processing of gas to the transmission pipeline system. 3. Commercial gas production at the Titas Gas Field began in April 1968. Over time, wellhead pressure of wells has been decreasing at an average annual rate of 90 pounds per inch (psi) and within the next 3-5 years, it is estimated that natural gas flow can no longer maintain the gridline pressure without the installation of compressors before the existing natural gas process plants at Location A in the Titas Gas Field. Gas compressors will be essential to augment gas transmission capacity to meet the increasing gas demand. Project Description 4. Component 1 will be located in about 0.6 hectare (ha) of land within the existing facility owned by BGFCL at Location A of the Titas Gas Field. No unauthorized public access to Location A is allowed by BGFCL. The existing natural gas processing facility of BGFCL at Location A of Titas Gas Field consists of major equipment such as eight glycol dehydration units, four low-temperature separation (LTS) units, and two LTS units with glycol injection. Two fractionation units separate the condensate, which is a by-product of gas processing, into liquid fuel as motor spirit (MS) and high speed diesel (HSD). MS and HSD are sold to Padma Oil Company Limited, and Meghna Petroleum Limited. The two gas treatment plant and one of the fractionating plants were financed by ADB.1 5. Component 1 will consist of seven reciprocating compressors with a capacity each of 60 million standard cubic feet (MMSCF) per day of natural gas. Five compressors will be operating at a time while two compressors will be standby. The compressors will require 5 MMSCF of natural gas daily as fuel for its operation and 16 tons of water per day for its closed recirculating cooling water system. Water requirements will be provided through borehole/deep tube well from the existing BGFCL natural gas processing plant facility. Make up water for the cooling system will be required only when leakage has occurred at pump packings through years of operation or when water has been drained to allow system repair. The daily output capacity of compressed gas from these compressors will be 300 MMSCF. Activities associated with the installation of the compressors from construction, testing and/or commissioning, and operation will follow relevant regulations of the Government of Bangladesh (GoB) and applicable industry and international standards. 1 ADB.
