Screening guidelines and data analysis for the application of in-situ polymer gels for injection well conformance improvement
… that determines the applicability of three injection well gel technologies including bulk gels, colloidal dispersion gels, and weak gels. Comparative analysis, statistical methods, and a machine learning technique were utilized to develop a conformance agent selection advisor that consists …

An Engineering Analysis Method for Deep Geothermal Energy
… system, which is a doublet system with one injection well and one extraction well. A convective heat transfer boundary between the aquifer and overburden layers is applied for the axisymmetric problem based on the Lauwerier model for the first time. A new analytical solution is deduced using …

Seismic attribute analysis and CO2 monitoring within the Mississippian reservoir, Wellington field, Sumner County, Kansas
… study in the Mississippian chert reservoir at Wellington field, Sumner County, Kansas to determine the feasibility of injecting CO2 for enhanced oil recovery (EOR) and geologic storage of CO2 in this geological environment. This study evaluates the use of seismic methods for imaging the …

In Situ Heavy Oil Upgrading Through Ultra-disperse Nano-Catalyst Injection in Naturally Fracture Reservoirs
… Upgrading” which produces EOR and Upgrading by injection of a hot fluid, in this case vacuum residue from the heavy oil produced, with suspended nano-catalytic particles flowing down-hole along with dissolved hydrogen as precursor of partial Hydroprocessing of the residue. The combination of …

A Calculation Model for Steam Property Variation Along Wellbore Trajectory in SAGD Process
… In a typical SAGD process, two horizontal wells were drilled inside the target formation, one is put on the top as steam injection well and another is usually put on the bottom of target formation as oil production well. During SAGD process, a large amount of high pressure high temperature …

Injection Induced Seismicity Modeling and Application to the Karapiti Reinjection Area, Wairakei, New Zealand
… behaviours and earthquake rupture process in injection induced earthquake areas with a coupled numerical model. The physics based numerical modelling specially designed for injection induced seismicity integrates fluid flow, heat transfer, mechanical deformation and seismic rupture sequences. …

Groundwater Modeling of Managed Aquifer Recharge at the Regional and Local Scale
… to build water resiliency for the district as well as meet recent regulations concerning effluent released into the Chesapeake Bay. The Sustainable Water Initiative for Tomorrow (SWIFT) project will include five injection well fields across the Virginian Coast. The first of these fields to be …

Imaging the Soultz Enhanced Geothermal Reservoir using double-difference tomography and microseismic data
… that velocity structure for S-waves correlates well with seismicity and show the expected low velocity zones at depths between 2900 and 3600 meters, where fluid was believed to have infiltrated the reservoir. P-wave velocity structure shows less of a correlation with seismicity and shows low …

Carbon Dioxide Storage in Coal Seams with Enhanced Coalbed Methane Recovery: Geologic Evaluation, Capacity Assessment and Field Validation of the Central Appalachian Basin
… was successfully injected into a coalbed methane well in Russell County, Virginia as the first carbon dioxide injection test in the Appalachian coalfields. Research from the field validation test identified important injection parameters and vital monitoring technologies that will be applicable to …

Hydraulic and Electrokinetic Delivery of Remediants for In-situ Remediation
… in variably saturated zones. Model predicted well head data were in very good agreement with field observations. Simulation results showed that the injected slurry migrated radially outward from the injection well and that nZVI travel distance increases were not proportional to the increase in …

Ultrasound Testing System for the Detecting of the Shape and Growth of a Vapor Chamber in the VAPEX Process
… injected into the reservoir through a horizontal injection well. As the solvent vapor comes into contact with the heavy oil, it dissolves in the oil and reduces its viscosity. The mobilized oil then drains into the second horizontal production well. After the breakthrough of the vapor chamber from …

Predicting the Dynamics of Injection-Induced Earthquakes
Human activities associated with the injection of fluids at depth are known to trigger earthquakes. Fluid injection increases the internal pore pressure of the host rock, which in turn reduces the effective stress and frictional resistance of faults that maintain the fractured rock system in a …

Numerical Simulation and Optimization of CO2 Sequestration in Saline Aquifers
… the detailed mechanisms of GCS are not well-understood. As a result, there remain many uncertainties in determining the sequestration capacity of the formation/reservoir and the safety of sequestered CO2 due to leakage. These uncertainties arise due to lack of information about the …

Ultrahigh-resolution paragenesis of the Cambrian-age Mt. Simon Sandstone at a burial depth of 1.8-2.1 km, Illinois basin, USA
… from the Illinois Basin-Decatur Project CCS injection well. The 1.8-2.1 km interval of the well was sampled using a Schlumberger mechanical sidewall coring tool, a Modular Formation Dynamics Tester (MDT) and openhole wireline tools. Sidewall cores were extracted from seven stratigraphic …
