Sweet Spots Discrimination in Shale Gas Reservoirs Using Seismic and Well-logs Data. A Case Study from the Worth Basin in the Barnett Shale

Sequence stratigraphy and its application in marine shale gas exploration: A case study of the Lower Silurian Longmaxi Formation in the Jiaoshiba shale gas field and its adjacent area in southeast Sichuan Basin, SW China

“…Although the success of shale gas exploration in North America leads geologists to believe that shale gas exploration has a good prospect, how to find the sweet spot of shale gas in shale strata is still the main obstacle we need to face in the shale gas exploration. In order to find the sweet spot of shale gas, a lot of work has been done by geologists and engineers through numerical modeling (Wang and Carr, 2013a,b), seismic velocities (Jaiswal et al, 2014), seismic inversion (Peng et al, 2014), well logs data (Aliouane and Ouadfeul, 2014).…”

Introductory Chapter: Oil and Gas Wells - Advances and New Challenges

“…For example, in the oil and gas domain, we can distinguish two kinds of oil and gas types which are conventional and unconventional; they have the same chemical characteristics and components; the only difference between them is in their way of extraction, since the conventional oil and gas are small quantities easy to develop with low cost; however the unconventional hydrocarbons are huge quantities requiring advanced technology to develop them with increasing price [3,5] Figure 3. Shows the different kinds of conventional and unconventional oil and gas resources.…”

Parametric Investigation of De-Sulfurization Process for Sour Gas; Introduction of Novel System

“…In natural gas, sulfur is present mainly as hydrogen sulfide gas (H 2 S), while in crude oil it is present in sulfur-containing organic compounds which are converted into hydrocarbons and H 2 S during the hydro desulphurization [9][10][11][12][13]. In both cases, corrosive, highly-toxic H 2 S gas must be converted into elemental sulfur and removed for sale or safe disposal [14][15][16]. Formation fluids that contain Hydrogen Sulfide -By-product from anaerobic bacterial action on sulfur compounds present in the mud (i.e.…”
