.... Thin section analysis is typically used to determine sample dispersed clay volumes and the resulting macroporosity. Correlations between laboratory measured total porosity and volumes of dispersed clay may also allow dispersed clay porosity to be estimated. This additional degree of freedom...

... learning algorithms are shown to yield similar composition for C 1 –C 6+ and GOR as obtained from PVT reports. Data are shown from three separate crude oil samples with excellent matching of laboratory and downhole spectra. DOWNHOLE FLUID ANALYSIS Wireline formation samplers collect live fluid samples...

... laboratory to another, and it can be costly to acquire cores and if many analyses are required. The main objective of this study is to test a new innovative method of extracting probability-based analog rock properties, the digital twin (DT), from high-resolution images (HRI) of thin sections (TS...

... of load is shared by pore fluid and the ‘α’ is much smaller than unity. Biot's coefficient ‘α’ is expressed in terms of bulk modulus (Kb) and matrix modulus (Kma). Kb is estimated from acoustic logs as well as measured by hydrostatic compression tests in the laboratory. However, Kma is much more...

... is the key to better understanding what fluids are present and in what quantities. It is well agreed upon that changes in pressure and temperature as rock is taken from downhole, handled and transported to a laboratory facility affect the contents of the pore system. This generally results in a varying...

... to a laboratory for analysis, which takes place weeks to months later. By the time the laboratory has performed an analysis, the section has been cemented, and perhaps the rig has finished operations and moved onto the next phase. Success of the sampling operation is predicated on the samples being acquired from...

These questions are where to sample, when to sample, and how to sample? Samples must be acquired from the right locations in order to answer the critical questions...

... Rock Physics or Digital Rock is a rapidly advancing image-based technology for predicting subsurface properties of complex rocks (e.g., porosity, permeability, formation factor) to achieve more, cheaper, and faster results as compared to conventional laboratory measurements. We show that a combination...

... also constructed the 3D pore network to observe the pore structure, quantify connectivity and specific surface ratio to study their influence on permeability. We found that laboratory measured permeability from core plugs was strongly correlated to the equivalent pore radius calculated from micro-CT...

... such uncertainties. Different methods can be used to estimate dry-weight mineral fractions. Some methods are applied downhole such as neutron-induced spectroscopy (w/spectral gamma ray), while other methods such as X-ray fluorescence (XRF) and X-ray diffraction (XRD) are applied on core in the laboratory...

... or ‘ground truth’. However, inconsistency in sample preparation and analytical techniques within, and between laboratories creates significant uncertainty in calculating the free and adsorbed gas components which constitute total gas. Here we present an analytical program performed on samples of core...
