Abstract Although stochastic modeling methods can achieve multiple implementations of sedimentary microfacies model in dense well blocks, it is difficult to realize continuous convergence of well spacing. Taking the small high-sinuosity meandering river sediments of the third member of Quantou Formation in Songliao Basin as an example, a deterministic modeling method based on geological vector information was explored in this article. Quantitative geological characteristics of point bar sediments were analyzed by field outcrops, modern sediments, and dense well block anatomy. The lateral exten

Based on geological conditions, Indonesia is located between the Indo-Australian plate, the Eurasian plate, and the Pacific plate, making Indonesia prone to tectonic earthquakes. However, since the big earthquake that occurred in Aceh on December 26, 2004, the geological conditions in Sumatra have undergone significant changes marked by stressful situations in the western to southern regions of Sumatra, especially on Sibayak Volcano. This study used data from BMKG and Global CMT, which included magnitude (Mw), depth, earthquake coordinates (longitude and latitude), type of earthquake, strike,

AbstractLaumontite is a common zeolite mineral indicative of low-grade metamorphism of lavas and volcaniclastic sediments. Stoichiometric laumontite (CaAl2Si4O12·4.5H2O) dehydrates in air at 298.15 K, 1 bar to leonhardite (CaAl2Si4O12·3.5H2O) via loss of water from the W1 crystallographic site. Consideration of reported X-ray diffraction and calorimetric data indicates that the standard molal volume and entropy for dehydration of laumontite to leonhardite + liquid water are ∼13 cc/mol and ∼8 cal/molK, respectively, at 298.15 K, 1 bar. Equilibrium between laumontite and leonhardite occurs at 70

The subtle reservoir has become an important exploration target within the Bohai Bay Basin, especially in the Qikou sag. In order to guide subtle reservoirs exploration in offshore area geological analysis to Sha’nan structural belt is carried out in this paper. Qikou sag has large thickness, high abundance, ideal type hydrocarbon source rock. By unconformity recognition technique and paleotectonic analysis technique, results show that tectonic uplift had provided sedimentary source to the depression around it after Es1. By 3-D seismic interpretation technique and Seismic facies analysis, the

Remote sensing infrared spectrometer data were collected with the Geophysical and Environmental Research Corp. 64 channel scanning spectrometer. These have been used to delineate geological units and, subject to some ambiguity, identify their mineralogy. Results are given for a survey area near Coppin Gap in the Pilbara region of Western Australia. Here, clear distinction was obtained between the sericite mineralogy of the Hardey Sandstone and some members of the Marble Bar belt, and the carbonate or epidote/chlorite mineralogy of the Kylena Basalt and other units in the Marble Bar belt.From t

Large-jointed rock mass is the main geological condition of transmission lines of Qingyuan Regions in Guangdong Province. The bolt foundations haven’t be studied and applied in this geological condition. Static load tests of 15 single-bolt foundations and 8 group-bolt foundations were carried out. Experiment study shows that the mechanical characteristics of bolt foundation are suitable for transmission lines in large-jointed rock mass. The design parameters of anchor bar in large-jointed rock mass are derived from the measured data:τa>2359kPa, τb>618kPa, τc>42kPa.

The developed litho-sedimentological model of deposits of the YUV1productive horizon makes it possible to choose the most effective technique for supplementary exploration of a natural reservoir and improve the quality of geological justification for its subsequent development. The research objective is to carry out paleogeographic and paleostructural reconstructions, to identify facies complexes in the Upper Jurassic productive deposits, and to identify zones for the development of improved reservoir units. With the help of paleogeographic and facies methods, the geological regularities of th

Beach-bar sand in lacustrine facies represents one of the most significant reservoirs. Depending on the depositional characteristics, it can be further divided into two different sedimentary microfacies, beach sand and the bar sand. Favorable reservoirs are often developed in bar sand. The lower section of the upper part of the 4th member of the Shahejie Formation in the Gao89-1 block is a typical nearshore shallow water beach-bar deposit. Oil distribution is influenced by lithofacies and physical properties. In order to better characterize the heterogeneity within beach-bar sandbodies, a mode

Then we promoted it in the whole region, and characterised the sedimentary faices of every layers. So we provide a reliable geological basis for progressive development in research area.
