Paper presented at the SPWLA 64th Annual Logging Symposium, June 10–14, 2023
Paper Number: SPWLA-2023-0027
.... 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...

Paper Number: SPWLA-5042
... 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...

Also, samples must be taken in a manner that provides the laboratory with the most representative analysis of the subsurface reservoir fluid. Carbon dioxide is a corrosive acidic gas component often found in petroleum reservoirs...

... 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...

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...
