Precision porosity and facies determinations are critical in reducing drilling uncertainty increasing hydrocarbon recoveries from heterogeneous sources. The distribution of the Taiyuan-Shanxi Formations (T9c-T9d), Shihezi-1 Formation (T9d-T9e) within Hangjinqi area uncertain no studies have covered spatial on a regional scale. nature coal, mudstone, sandstone makes it challenging to comprehend lithofacies. Also, seismic resolution is not able resolve reservoir heterogeneity. Therefore, we...
Introduction Milankovitch theory has extensive application in sequence stratigraphy and the establishment of time scales. However, it is rarely applied to shallow strata rich hydrates. Cyclostratigraphic analysis Quaternary unconsolidated sediments can help identify climate sea level changes that correspond orbital cycles improve our understanding dynamic evolution Methods Using natural gamma-ray log data from deepwater area well W01 Qiongdongnan Basin, cycle was conducted primary...
The vague understanding of the coupling relationship among natural gas charging, reservoir densification, and pressure evolution restricted tight exploration in Lower Shihezi Formation Hangjinqi area, north Ordos Basin. In this study, quantitative porosity model, process, charging history sandstone reservoirs were constructed by integrated investigation property, thin section, SEM cathode luminescence observations, fluid inclusion analysis 1D basin modeling. results show that compaction...
Statistical analysis of massive laboratory analytical data shows that for intervals in the Upper Ordovician Wufeng Formation and Lower Silurian Longmaxi Fuling area, Sichuan Basin, total organic carbon content is 0.55%–5.89% with an average 2.54%, presenting a gradual increase trend from top to bottom. Based on whole-rock X-ray diffraction data, clay minerals shale 16.6%–62.8% 40.9%, gradually decreasing The brittle increases bottom, ranging 37.2% 83.4% 59.1%. Porosity 1.17%–7.98% 4.61%...
The lack of data on the complex tectonics Qiongdongnan Basin has thus far restricted our understanding overpressure, deep hydrocarbon and shallow gas hydrate distribution. We therefore combined integrated seismic, well borehole test with basin models to clarify relationship between tectonic activity overpressure evolution, as potential effects subsurface pressure accumulation. results show differences in characteristics eastern western basins. Large numbers faults magmatic intrusions have...
<title>Abstract</title> The Youjiang Basin is the main area of Middle Devonian shale gas resources in southern China, with complex geological conditions, diverse stratigraphic structures, low level exploration and limited hydrocarbon data. In this study, a method proposed for evaluating regional preservation by which it easy to obtain information (using available data from maps) process (processed computer software). This was applied evaluation conditions Basin. Information extracted...

Abstract Pore-throat size distribution is a key factor controlling the storage capacity and percolation potential of tight sandstone reservoirs. However, complexity strong heterogeneity make it difficult to investigate pore structure reservoirs by using conventional methods. In this study, integrated methods casting thin section, scanning electron microscopy, high-pressure mercury intrusion (HPMI), constant-pressure (CPMI) were conducted study pore-throat its effect on petrophysical...
Abstract The deep volcanic and clastic rocks in the Songliao Basin are typical tight reservoirs with ultralow porosity permeability. Natural fracture determines effective strata. Integrated core thin section observations, image logging, physical property measurement, X-ray diffraction, seismic attribute analysis were applied to ascertain characteristics genetic mechanisms of tectonic fractures Huoshiling-Shahezi Formations Gudian half-graben. contribution was also discussed. Results showed...
This work systemically investigates the wettability and pore connectivity their potential influence on gas recovery from three overmature marine shales (Niutitang, Longmaxi, Donggangling Formations) in southern China with a range of total organic carbon (TOC) contents, mineralogical compositions, geometry characteristics. To achieve these objectives, TOC, X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), contact angle, spontaneous fluid imbibition were performed....
