This article presents a novel methodology for data integration including laboratory data, the results of standard well logging measurements and interpretation XRMI imager determination porosity permeability fracture system in carbonate rock. An example micro computed tomography applied rock is included. Data were obtained on area Polish Lowland Zechstein Main Dolomite formation. The input set i...

This paper studies the problem of steering a linear system subject to state and input constraints towards goal location that may be inferred only through noisy partial observations. We assume mixed-observable settings, where system's is fully observable environment's defining partially observed. In these planning an infinite-dimensional optimization objective minimize expected cost. show how re...

Overmature continental shales are widely distributed in China, while few investigations have been conducted. The pore structure is a critical parameter controlling the resource potential of shale gas. However, and heterogeneity from Shahezi Formation, Xujiaweizi Fault, Songliao Basin not well revealed. In this study, helium porosity permeability, low-temperature N2 adsorption (NGA), mercury int...

Microbially induced calcium carbonate precipitation (MICP) technology has attracted widespread research attention owing to its application in crack healing for cement-based materials an intelligent and environmentally friendly manner. However, the high internal alkalinity, low nutrient content, dense structure of have restricted self-healing materials. Various carrier been widely used immobiliz...

In this text, a method to use CO2 for the treatment of calcareous sand is presented. Carbon dioxide solidification-bacteria (Streptomyces microflavus) was obtained by screening and applied mechanical strengthening through microbial mineralization/carbonization process. Experiments in both liquid phase were carried out. The optimal mass ratio carbon solidification-bass cteria calcium oxide found...

Understanding the pore networks of unconventional tight reservoirs such as tight sandstones and shales is crucial for extracting oil/gas from such reservoirs. Mercury injection capillary pressure (MICP) and N2 gas adsorption (N2GA) are performed to evaluate pore structure of Chang-7 tight sandstone. Thin section observation, scanning electron microscope, grain size analysis, mineral composition...
