Rate-Transient Analysis of Tight Oil and Gas Reservoirs
… technologies applied to low-permeability (tight) oil and gas reservoirs in recent decades, resulting in commercial production. For each stage in a MFHW, the formation is fractured by injecting water and sand at high pressure. The resulting hydraulic fracture system enhances production from tight …

Simulation of the dynamic response of a damped taught string
… by the increase of the depth of exploited oil and gas reservoirs. This thesis discusses the changes in the dynamic behavior of marine pipelines and proposes a simple simulation based on a taut string. The dynamic response of the taut string is modeled using two techniques, the Green's …

SUSTAINABILITY ASSESSMENT OF LARGE-SCALE CARBON CAPTURE AND SEQUESTRATION DEPLOYMENT OUTSIDE THE SYSTEM BOUNDARIES - OPPORTUNITIES AND CHALLENGES
… the combustion of fossil fuels, primarily coal and natural gas. As a result, greenhouse gases (GHGs) are generated, and they act to trap radiant heat from the Earth. When GHGs are discussed, attention is usually concentrated on carbon dioxide (CO2) because it is believed to be the most …

Use of 3D Seismic Azimuthal Iso-Frequency Volumes for the Detection and Characterization of High Porosity/Permeability Zones in Carbonate Reservoirs
… controlling the production from conventional oil and gas reservoirs is the distribution of porosity and permeability within the producing geologic formation. The geometry of the pore space within these reservoirs, and the permeability associated with this pore space geometry, impacts not only …

Reconstructing lithofacies of the Norphlet Formation (Jurassic) as potential exploration targets: Little Cedar Creek and Brooklyn Fields, southwest Alabama
… located across the southeastern United States and offshore Gulf of Mexico. The eolian dune sands present in the Norphlet Formation serve as oil and gas reservoirs, making the formation of particular interest to oil and gas companies. Stable Appalachian ridges are the source of the Norphlet …

Reservoir characterization of the Hartselle Sandstone in the vicinity of Gorgas Power Plant, using amplitude variation with offset (avo)
The Black Warrior Basin (BWB) contains prolific oil and gas reservoirs, which have been well characterized to the west of two major coal-fired power plants in Alabama. The Mississippian Hartselle Sandstone of the BWB is a major oil sand resource in the United States. A stratigraphic test well, …

CFD-based erosion modelling of simple and complex geometries
Choke valves are important components in oil and gas production systems that are used to control the pressure and flowrate of fluids issuing from oil and gas reservoirs. The presence of sand in the production fluids can cause considerable damage to such components, and as sand is increasingly …

Stratigraphy and Structural Geometry at the Leading Edge of the Montana Thrust Belt, East of Sun River Canyon, Lewis and Clark and Teton Counties, Montana
… the structural traps that contain hydrocarbon (oil and gas) reservoirs in southwest Alberta, but little research has been conducted south of the Canadian-United States border along structural trend into Montana. Relating the structural geometries and stratigraphy of the Sun River Canyon triangle …

Effect of Heating Rate on Thermally Induced Pore Water Pressure and Crack Evolution in Clay and Shales
… heating rates influence temperature distribution and the evolution of pore pressure under elevated temperatures. Clay shales, characterized by their extensive geological presence and low hydraulic conductivity, carry immense importance across a wide array of applications, including their pivotal …

An experimental and numerical study on the fracturing processes in Opalinus shale
… extraction of hydrocarbons from unconventional oil and gas reservoirs relies on a detailed understanding of the fracture processes in shale. Also, underground structures designed for nuclear waste repositories are typically constructed in shale due to its characteristic low permeability. To …

Unified interpretation of nonlinear elasticity in granular solids, A
Granular solids such as natural rocks and concrete show nonlinear elasticity in response to dynamic deformation with a large strain amplitude. Resonance experiments can measure the nonlinear elasticity using resonance curves which show response amplitudes as a function of driving (oscillation) …

Data-Driven Analytics for Oil and Gas Reservoir Production Forecasting
… flow simulation models preserving a robust and reliable model of oil and gas reservoir is often deterministic, cumbersome and expensive (manpower and time consuming). Presence of a high-dimensional data space consisting of a large number of operational and geological parameters impedes …

CO2-rock interaction during CO2-enriched brine injection into storage reservoirs using NMR integrated with fiber optic sensors
… new technologies need to be urgently developed and employed on a large scale. One promising method is to capture anthropogenic CO2 and store it in geological formations, e.g. depleted oil and gas reservoirs and saline aquifers. This process is referred to as carbon capture and storage (CSS). The …

Geophysical properties of carbon monoxide when used as an enhanced oil recovery agent
ABSTRACT Many reservoirs witness decreased production related to the mobility of hydrocarbons given the composition of the fluids and rocks, and the reservoir environment (ie: temperature and pressure). Enhanced oil recovery (EOR) efforts attempt to manipulate these conditions to reach profitable …

Hydraulic fracturing of artificially generated soft sandstones
Fractures are considered to be both problems and opportunities for exploration and production from petroleum reservoirs. The main aim of fracturing an oil medium is the stimulation of oil and gas production by inducing highly conductive channels leading to a well, from which hydrocarbons will flow. …
