To study the effect of magma intrusion on thermal evolution low-rank coal with high moisture content, relationship between content variation and conductivity was analyzed by COMSOL Multiphysics numerical simulation field validation. Taking Daxing Mine in Tiefa coalfield as research background, effects finite time mechanism volatilization organic maturity seam are investigated this paper. The re...

Abstract Numerical 3D basin modeling is used to reconstruct the burial and temperature histories in onshore northeastern Netherlands, incorporating four main geological structural elements Groningen Platform, Lauwerszee Trough, Friesland Lower Saxony Basin. The framework based on recently published open access depth surface data; public vitrinite reflectance data from 28 wells are evaluate hist...

Organic geochemical evaluation of the Madbi Formation as the main source rock of the Al-Jawf Basin, NE Central Yemen was the main objective of this study. The organic geochemical methods used in the study include: rock-eval pyrolysis, total organic carbon, and optical measurements as the vitrinite reflectance and thermal alteration index. In this study, 67 well core and side-well core samples o...

Lacustrine shales hold a huge potential oil resource in China. Pore properties (pore volume, diameter, specific surface area, and fractal dimensions) their relationships with geological factors (mineralogy, insoluble organic carbon, burial depth, vitrinite reflectance) are critical for evaluating shale resource. However, the controlling pores lacustrine remain unclear, as between pore of Soxhle...

The overmature Precambrian to Lower Paleozoic marine shales from China contain relatively simple organic matter (OM) composition, which is dominated by in-source solid bitumen (i.e., in the hydrocarbon source rocks). thermal evolution behavior of original OM and determination maturity Cambrian have been challenging for decades. vitrinite-like maceral (VLM) widely present these shales, its origi...

Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...

Commercial hydrocarbon discoveries in the Cretaceous of the southern Persian Gulf basin provide direct evidence that there is an effective petroleum system associated with the Cretaceous series. The revised models of thermal maturity in this region are needed to investigate lateral and stratigraphic variations of thermal maturity, which have not so far been addressed in detail for this part of ...

Shale oil and source rock samples of the Carboniferous Keluke Formation from well Chaiye 2 in Delingha Depression were analyzed by gas chromatography–mass spectrometry. Source rocks highly mature at generation stage with vitrinite reflectance (Ro) 1.45–1.88%. However, produced shale reservoir was characterized abundant biomarkers but low abundance diamondoid hydrocarbons estimated Ro ca. 0.78%,...

Shales contain magnetic minerals generally at very low concentrations. In the early stages of diagenesis, inherited are altered, while nanominerals formed. this study, we proposed a study shales over stratigraphic thickness 1.3 km from borehole in Paris basin (Borehole EST 433, France), and same formation (Opalinus Clay) collected seven boreholes Jura molasse (Swiss). Magnetic measurements expe...
