The Taranaki Basin in New Zealand presents the most promising territory for strategies of hydrocarbon exploration and development. This basin contains multiple source rock levels its sedimentary successions formed during syn- post-rift periods. deepest rocks, found Rakopi Formation, were deposited deltaic to deep marine environments consist gas-prone coal organic-rich mudstone lithofacies. Howe...

Oil shales are developed in the Shale Member of Middle Jurassic Shimengou Formation Qaidam Basin, China. The oil can be classified into three quality groups (low-, medium-, and high-quality shales) through a comprehensive analysis protocol that includes Rock-Eval pyrolysis, total organic carbon (TOC) content, proximate analysis, gas chromatography-mass spectrometry (GC-MS), X-ray diffraction (X...

The influence of coalification on coal structure evolution in middle ranked coals is significant for physical assessment coalbed methane (CBM) reservoirs, which provides insights the intrinsic connection between jump and pore heterogeneity. A total 26 middle-ranked were samples covering Liupanshui Coalfield Guizhou Province, Anhe Henan Huaibei Anhui Sanjiang Basin Heilongjiang Ordos Shaanxi Pro...

Coal maceral composition has a great effect on gas adsorption and diffusion. The interaction between supercritical CO2 (SCCO2) fluid will affect diffusion behavior in coals. Thus, the diffusivity derived from kinetics of CH4 vitrinite- inertinite-rich coals with low-violate bituminous rank collected Hancheng mine Weibei coalfield pre- post-SCCO2 exposure (SFE) were tested at conditions 45 °C 0....

Palynological study of Tungu Buzum Hill was investigated with a view towards determining the age outcrop, compare its miospore content adjacent Buzu Valley carbonaceous shale, their stratigraphic relationship and paleoenvironment deposition litho-sequence. Field involved litho-description logging achieved by noting rock type, mineralogical composition, bed thickness, texture, sorting, roundness...

Organic-matter-hosted pores are fundamental pore spaces in shale reservoirs, which largely control the expulsion and storage of oil gas. However, strong heterogeneity organic greatly increases complexity network make reservoir evaluation challenging. The reservoirs has beenone hottest topics recent years. In this review, their controlling factors systematically summarized. formation evolution d...

Purpose. To establish the petrographic and chemical-technological features of coal seams formation C12 Kalmius block. Method. General scientific applied research methods were used to fulfill tasks. With help methods, macroscopic microscopic characteristics composition studied in detail, degree its recovery metamorphism was determined. chemical technological a comprehensive description quality i...
