Electrical noise model for detection circuitry of an NMR-based formation evaluation Tool
… noise. For NMR equipment used in earth formation evaluation, this is rendered more difficult by the measurement geometry and noise of the samples under consideration. Schlumberger's proVISION logging-while-drilling tool is one such NMR device. It makes use of the technique of NMR to …

Quantification of rock fabric through multi-scale image data analysis for enhanced rock typing and formation evaluation
… properties of sedimentary geological formations. Quantification of rock fabric and its integration with rock classification and formation evaluation efforts are critical for reliable estimation of petrophysical properties in complex formations with rapid spatial variation in rock …

Application of statistical methods for "flow unit" identification and characterization of a reservoir using well log and core data
… important parameters to identify flow unit for formation evaluation, reservoir description, and characterization. Beyond evaluating permeability and porosity, one can also use combinations of two or more rock properties to gain insight into the character of two through porous media. Porosity is …

CO₂ geosequestration in the Lakota Formation, Powder River Basin, WY, USA
… sites, the Cretaceous deep saline aquifer Lakota Formation in the Powder River Basin has been suggested as a potential target. This thesis presents a quantitative feasibility study for carbon geosequestration within the Lakota Sandstone Formation. The assessment consists of formation evaluation, …

Oil Potential of Middle Cretaceous Tight Carbonate in Mexico
… a tight overpressured Cretaceous carbonate formation in Field A of Mexico. The Cretaceous carbonate was penetrated by well A1 and tested oil successfully during an open-hole test covering interval 5356 to 5515 m (MD) that produced oil of 33 degrees API. Initial pressure was 1050 kg/cm2 at …

An experimental investigation on Archie parameters at ambient and overburden conditions of clean reservoir rocks.
… reservoir rocks. The samples were from sandstone formations (North Sea), and carbonate formations (Sirte Basin, Libya). Although much work has been carried out on the electrical properties of sandstones (which are considered as ideal representatives of clean reservoir rocks) few experimental …

Computation of pseudosonic logs in shallow fresh/brackish water wells: a test case in Brunswick, Georgia
Due to the usefulness of sonic logs in formation evaluation, efforts have been made to develop a method for calculating pseudosonic logs for wells in which sonic logs were not originally obtained. These efforts attempt to use electrical resistivity data in the calculation of pseudosonic logs by …

Application of Machine Learning and Deep Learning Methods in Geological Carbon Sequestration Across Multiple Spatial Scales
… security simultaneously. The pre-injection formation characterization and post-injection CO2 monitoring, verification, and accounting (MVA) are two critical and challenging tasks to guarantee the sequestration effect. The tasks can be accomplished using core analyses and well-logging …

Improved petrophysical evaluation of consolidated calcareous turbidite sequences with multi-component induction, NMR, resistivity images, and core measurements
… approach to improve the petrophysical evaluation of thinly bedded sand-shale sequences that have undergone extensive diagenesis. Formations under analysis consist of carbonate-rich clastic sediments, with pore system heavily reworked by calcite and authigenic clay cementation, giving …
