| Abstract | As the oil prices keep increasing annually and the conventional HC resources continue to be depleted. The unconventional gas in generally the gas from shale in particular, becomes a new and more alternative of additonal HC resource. Shale gas has got increasing Several countries have taken the first step to develop their own resources. In Asia, China is the richest of shale gas and also has the most rapid development. Having looked back to the South East Asia countries, From now, there are only two countries which have the official shale gas reserves, i.e. Indonesia and Malaysia. How can we develop shale gas as fast as China or US? In addition to raising the awareness in a systematic assessment of shale gas potential reserve in each SE Asian country one need to know better on the shale gas Exploration and Production technology as well as the lesson from the countries like US and Chaina. This study will have a comprehensive overview on development of the shale gas E&P around the world. Reviewing in testing methods which needed in assessment of shale gas Show the complete sequences of shale gas exploration which can be used as the first guidance for this type of unconventional resources. Aply the assessment/evvaluation criteria of shale gas to preliminary determine the shale gas possibility of some basins in Thailand And do perform a deep assessent of shale gas for the Fang Basin. Thailand has a lot of shale gas basin prospects which have portential in shale gas production as following: Phitsanulok Basin, Petchabum Basin, Lapeangsean Basin, Sakon Basin, Connabot Basin Phu Horm Basinm, Phu wiang Basin, Nam Phong Basin, Dong Mun Basin, ergui Basin, Pattani Basin and Songkhla Basin by comparing geochemical and geological data with US basins. The most potential of shale gas in Thailand is Phitsanulok Basin with the biggest basin oil/gas onshore. Shale of this basin has high TOC, huge thickness of shale, proper shale depth and shale can release gas. However main shle of Phitsanulok Basin in light, Dark mudstoone which does not includes of brittle minerals (e.g. carbonate, Quart). The Brittle mineral of shale is very important for hydraulic facturing then shale of Phitsanulok Basin still need more core data to vealuate fracturing devlopment. By Performing deep eveluation of shale gas in Fang Basin, due to this basin quite lacks of data. The data can collect from only one hole which FA-WR_35-04 of Sansai field. The collecting geochemical data are TOC, gas chromatography, vitrinite reflectance and mineralogy. Fortunately, TOC value has positive relative with FR log then we can use TOC instead of GR log to determine shale zoning. Positive characteristics for the gas shale of FA-WR-35-04 hole are: a high TOC content which is range from 2% to 5%, a proper prospect shale depth which is from 2,100 m to 2,700 m depth, shale of FA-WR-35-04 hole is in a proper depth for fracture development and shale thickness is enough to be commercial gas shale, mineralogy of shale inclused of quartz which is the brittleness mineral, it can dofracturing as well and gas chromatography shows that two shale layers can release gas. However the negative parameter for the gas shale is thermal maturity cannot reach the optimum theral maturity for gas generation but it is in oil and wet gas window. Anyway there's a Chance for Sansai field to have gas accumulation due to a sign of gas releasing form shale. |
