Advanced response matrix methods for full core analysis
Modeling full reactor cores with high fidelity transport methods is a difficult task, requiring the largest computers available today. This thesis presents work on an alternative approach using the eigenvalue response matrix method (ERMM). The basic idea of ERMM is to decompose a reactor spatially …

NMR Studies of Enhanced Oil Recovery Core Floods and Core Analysis Protocols
… life of oilfield wells. Laboratory-scale core floods, in which one fluid displaces another from the pore space of a rock core, are widely used in petroleum research for oilfield evaluation and screening EOR processes. Achieving both macro- and pore-scale understandings of such fluid …

The influence of micro-porosity on drainage relative permeability using digital core analysis
… flow is first examined through a critical length analysis and then confirmed using a flux analysis technique on the fully resolved pore space. Unified Brinkman equation is then solved to facilitate the coupling of Stokes and Darcy equations in the macro-phase and homogenised micro-phase. For …

Enhancing Special Core Analysis Insights into Wettability through the Application of Magnetic Resonance
… substantially increasing emissions. Special core analysis aims to aid optimisation of improved/enhanced oil recovery (IOR/EOR) fluids to increase hydrocarbon production from existing fields by altering the wettability of the system. Wettability is the preference of a fluid to adhere to the …

Prediction and measurement of special core analysis petrophysical parameters in the Nubian sandstone of the North Africa
… neural networks for estimating special core analysis (SCAL) parameters from minimal core training data and wireline logs. The SCAL data was obtained from measurements on core plugs undertaken at the Libyan Petroleum Institute (L.P.I). Previous neural network studies have attempted to …

The geologic history of Lake of the Woods, Minnesota, reconstructed using seismic-reflection imaging and sediment core analysis
… the formation of UNCF-2. Piston-type sediment cores collected from the southern basin of LOTW at depths that correspond to the middle of SU-D contain high amounts of organic material and charcoal fragments and sediment that are probably not related to Lake Agassiz. Instead, they were likely …

A Log and Core Analysis of the Marmaton Group, Granite Wash Fan Delta in the Anadarko Basin, Washita County, Oklahoma
… and laterally. This combined with a lack of core or outcrop data has created confusion in the subsurface, and the Marmaton Group has remained largely unstudied in southern Washita County, OK.</p> <p>This study examined two sets of core, correlated over 90 wells logs, and examined thin …

Predicting a detailed permeability profile from minipermeameter measurements and well log data
… ways. These are pressure transient testing and core analysis. Both methods are expensive in their own ways. This research focuses on a way to minimize or limit the need for both of these testing procedures.;The purpose of this research was to utilize well log data, mainly gamma ray and density, …

Application of statistical methods for "flow unit" identification and characterization of a reservoir using well log and core data
… values, which are generally determined from the core analysis, are not usually available. The need for permeability values significantly limits the identification of Flow Units in reservoirs where core analysis is not abundant.;In this study, in a complex reservoir in West Virginia was …

Profiling of Relaxation Time and Diffusivity Distributions with Low Field NMR
… resonance (NMR) is a common tool utilized in core analysis. NMR can reveal important information about pore structure, fluid configuration and wettability. However, standard NMR core analysis techniques look at the sample as a whole or only at thin slices. Two NMR pulse sequences are …

Using value stream mapping to improve forging processes
… these maps are compared and contrasted. A set of core analysis questions is developed that summarize the various value stream mapping methodologies. The application of these questions to an enhanced value stream map is developed as a tool, hybrid value stream mapping. Hybrid value stream mapping …

Micro-Scale Simulation of Evaporation, Condensation and Transport in Porous Media
… is gaining momentum. The concept of Digital Core Analysis deals with measurements of virtual core and the purpose of such modeling is to replace conventional and special core analysis when the latter are not feasible. One of the challenging concepts in micro-scale simulation of porous media …

A Real -Time Core Extraction System for Soil Nitrates
… is not available. For this reason, an intact core extraction procedure was tested that might be used in the field for the prediction of soil nitrates. This system used an intact core analysis, where an extracting solution was pushed through a soil core held between two filters, and an ion …

An experimental investigation on Archie parameters at ambient and overburden conditions of clean reservoir rocks.
… saturation can arise if conditions used for the core analysis differ widely from those in the formation. The classical Archie's equation does not take into account the effects of these variables, and therefore it is recommended that the saturation exponent to be used in log analysis should be …

The controls on reservoir continuity within the late Mississippian Elkton Member at Caroline Field, Central Alberta, Canada.
… Sundre Unit #1 and Sundre Rundle B. Detailed core description was conducted on 49 wells within the area. Using the core descriptions and core analysis data acquired from IHS AccuMap®, statistical methods were utilized to understand reservoir quality within the Elkton Member of the Turner …
