Abstract The sandstone units of the Early Cretaceous Lower Goru Formation are significant reservoir for gas, oil, and condensates in Indus Basin Pakistan. Even though these sandstones rocks hydrocarbon exploration, diagenetic controls on properties poorly documented. For effective production, appraisal a promising reservoir, diagenesis must be comprehensively analyzed first. this study, core sa...

Seismic, core, drilling, logging, and thin-section data are considered to analyze the reservoir diversity in east, middle, west fan of Liushagang Formation steep-slope zone Weixinan Sag, Beibuwan Basin. Three factors primarily affect differences for systems: (1) Sedimentary mostly control scales characteristics drainage system microfacies. Massive high-quality reservoirs have shallow burial dep...

Abstract This paper aims to gain new insights into clastic buried hill reservoirs. For this purpose, the Permian sandstone reservoirs in Upper Shihezi Formation, Gubei low hill, Jiyang Depression, was taken as object. Referring evolution histories of and tectonics, diagenesis its coupling with tectonic activity were investigated, aid techniques like core observation, casting sheet scanning elec...

Abstract Diagenesis is the main reason for tight reservoir lithology, complex pore-throat structure, strong heterogeneity, and variable occurrence distribution characteristics of fluid in pore-throat, which directly restricts Chang 8 oil layer group Ordos Basin. Exploration development. Based on analysis a large number cores thin slices, through application scanning electron microscopy, high-pr...

Abstract Cretaceous is the key exploration target layer in eastern depression of North Yellow Sea basin, which has a good prospect for oil and gas exploration. Its huge resource potential attracted great attention from petroleum geologists. In this study, main rock types, reservoir space petrophysical characteristics controlling factors are studied through core observation, thin section identif...

The redeposition of pristine phosphorite plays an important role in phosphorus accumulation, which created reworked extensively on the continental shelf. This paper, using geochemical analysis combined with data from petrology and diagenesis, focuses reconstruction formation processes Late Cretaceous Thaniyat deposition northwestern Saudi Arabia, is a part famous large Neo-Tethys Ocean’s deposi...

Tight sandstone reservoirs are of interest due to their potentially favorable prospects for hydrocarbon exploration. A better understanding tight outcrop reservoir characteristics and influencing factors is thus needed. By laboratory observation, thin section analysis, experimental the current work carried out a detailed investigation densely sampled outcrops Shanxi Formation in Liujiang River ...

Characterization of deeply buried sandstones and their reservoir quality is paramount importance for exploring, developing, subsurface storage energy resources. High in commonly correlated with the occurrence grain coatings that inhibit quartz cementation. The development reliable models can predict relies on incorporating quantitative understanding these diagenetic processes. Hydrothermal expe...
