Aung Sinkha Marginal Development Step Change for Survival

The Aung Sinkha (ASK) field is a marginal gas field developed by PTT exploration and production public company limited. The field completed the basic engineering development phase. The overall field comprises with offshore wellhead platforms, onshore processing plant, onshore condensate offloading and personnel transfer facilities. The feed production transports from offshore wellhead platforms through an offshore export pipeline to ASK Onshore Processing Facilities for processing. The onshore processing plant was initially designed with a typical design concept, including the incoming system comprise of slug catcher and inlet separator in order to separate gas, condensate and produced water. The gas production from the separation system is then sent to gas compressor system to boost up pressure. In addition to be sent to gas dehydration system before export to the customer. The condensate system provides with 2nd stage separator, 3rd stage separator, condensate filter coalescer, condensate storage tank, condensate transfer pump, condensate loading gantry and condensate export metering system. The produced water is designed with a produced water evaporator, designed to evaporate and reduce the produced water volume as much as possible before disposal of the high concentration produced water to third party for further treatment. A flare system, thermal oxidizer, closed drain and open drain system are provided. For utility system, onshore processing plant designed with fuel gas treatment and conditioning system, instrument air system, nitrogen generator system, utility water system, diesel storage, treatment and transfer system, main power generator with backup power generator system are provided. For the overall area facility, initially overall ASK onshore development project comprised of ASK Processing Facility, ASK Condensate Offloading Facility and ASK Personnel Transfer Facility. The ASK Processing Facility is the location where the production plant and accommodation area located. The ASK Condensate Offloading Facility is the location nearby condensate offloading jetty, this area reserved for condensate offloading to condensate offloading tanker. The ASK Personnel & Material Transfer Facility is the location nearby material transfer jetty, designed for material storage, material supply, transfer and personnel transfer between shore and offshore wellhead platform.
