Review of Well Logs and Petrophysical Approaches for Shale Gas in Sichuan Basin, China

China has vast reserves of shale gas. Currently, shale gas is one of the focuses of the unconventional reservoir. Well logs play an import role in shale gas production, and it is the bridge connecting geology, geophysics and petroleum engineering. In the exploration stage, well logs are used to identify lithology, evaluate the parameters of mineral types and compositions, total organic carbon (...

Draft Genome Sequence of Microbacterium sp. TNHR37B Isolated from a Heated Aquifer Bore Well of the Great Artesian Basin, Australia

Microbacterium sp. strain TNHR37B was isolated from a geothermal bore well sample (50°C) collected from a region of coal seam gas extraction activities. The 3.5-Mb genome with a G+C content of 69.9% contained unique genes, and a low similarity value for average nucleotide identity using BLAST was observed with the available 73 Microbacterium sp. genomes.

estimation of water saturation from petrophysical logs using radial basis function neural network

estimation of reservoir water saturation (sw) is one of the main tasks in well logging. many empirical equations are available, which are, more or less, based on archie equation. the present study is an application of radial basis function neural network (rbfnn) modeling for estimation of water saturation responses in a carbonate reservoir. four conventional petrophysical logs (pls) including d...

Determining Record Linkage Parameters Using an Iterative Logistic Regression Approach

1. Abstract. Fellegi and Sunter (1969) developed an algorithm for linking records. Each pair of records is scored on a field by field basis. If the records agree on a given field, a bonus is added to the score. If they disagree, a penalty is subtracted from the score. The records are designated as a match provided the score exceeds a certain threshold. In order to employ this method, one has to...
