Numerical Modeling of CO2 Non-Dracy Flow in a Petroleum Reservoir
… during injection scenarios and oil flow during production. Other objectives will be to define non-Darcy flow criteria from Forchheimer’s number and analyze the amount of energy used by enhanced flow rates through injection and production wells. Methodology used to obtain results will reflect …

Evaluating Alternative Hydraulic Solutions to Limit Nutrient Contamination of an Aquifer in Southern California
… and minimize the risk of affecting the pumping wells. The study attempts to identify the best way to recharge the aquifer and influence movement of the nitrates so that polluted waters may have lower nitrate concentrations in the future, rather than allowed to encroach on critical production …

Fault-Controlled Damage and Permeability at the Brady Geothermal System, Nevada, U.S.A.
… reservoir potential and realizing energy production. Despite a general association with active faults, geothermal systems typically display heterogeneously distributed permeability that makes locating successful wells difficult. Faults are associated with complex distributions of secondary …

Monitoring for Enhanced Gas and Liquids Recovery from a CO2 'Huff-and-Puff' Injection Test in a Horizontal Chattanooga Shale Well
… gas emissions as well as enhance gas recovery in production wells. This is possible due to the sorption properties of the organic material within shales and their greater affinity for CO2 over methane. The phenomenon of preferentially adsorbing CO2 while desorbing methane has been proven in …

Development of a Groundwater Flow Model for Hungry Valley, Washoe County, Nevada
… strategy implemented in 2004 and additional production wells implemented in 2005 static water levels have improved and most appear to have stabilized with measurements taken through March 2010. There are currently four production wells: Well Nos. 4, 5, 7 and 8. The objective of this …

Application of the 3-D Hydro-Mechanical Model GEOFRAC in enhanced geothermal systems
… of the reservoir, it is possible to obtain the production flow rate. A parametric study was conducted in order to check the sensitivity of the output of the model. An attempt to explain how aperture, width and rotation (orientation distribution) of the fractures influence the resulting flow rate …

A method using drawdown derivatives to estimate aquifer properties near active groundwater production well fields
… In these settings, water levels from groundwater production wells offer a transient dataset that can be used to estimate aquifer properties. Well interference effects, if detectable at neighboring production wells, allow for an interrogated aquifer volume that is larger (and therefore more …

Investigation of Asphaltene Instability Under Gas Injection in Unconventional Reservoirs and its Impact on Oil Recovery Performance
… which can lead to deposition and blockages in production wells and reduce the flow of hydrocarbons during gas enhanced oil recovery (GEOR) techniques. This study aims to experimentally evaluate the impact of miscible and immiscible carbon dioxide (CO₂) and nitrogen (N₂) on asphaltene deposition …

Acoustic monitoring of hydraulic stimulation in granites
… include poor connectivity between injection and production wells during stimulation and difficulty predicting fracture growth (Tester, et al. 2006). This, coupled with notable advances in oil and gas recovery, has made hydraulic fracture mechanics the subject of considerable study. Acoustic …

4D seismic analysis: discriminating between saturation and pressure changes form a data acquired Offshore Equatorial Guinea
… of a producing oil field in order to increase production and mitigate risk. This is done by interpreting changes in water saturation and changes in effective pressure in the reservoir, which allows production to be maximized safely. In this project, I determined saturation and pressure changes …

Investigation of wellbore stability in a North Sea field development
… conduct wellbore stability based on exploration wells as basis for planning new offshore field developments with deviated and horizontal wells. A second objective was to investigate the use of a probabilistic approach to wellbore stability, and compare it to the conventional deterministic …

Single Well Completion and Management Strategies for Enhanced Recovery of Tight Oil Using Miscible Gas Injection
Tight oil production relies on the multiple transverse fracture horizontal well completion design with 50 or more parallel propped hydraulic fractures distributed along a long horizontal well. Less than 10% primary oil recovery from these wells creates a strong incentive for enhancing recovery from …

Discrimination and Enhancement of Fracture Signals on Surface Seismic Data
… and therefore play a great role in siting the production wells. Hence, it is very important that the exact location and orientation of fractures or fracture swarms is known. Numerical models show that the fractures may be manifested on seismograms as discrete events.A number of data processing …

Simulating gas production from hydraulic fracture networks : a case study of the Barnett shale
… shown that the hydraulic fracturing of vertical wells produces an extremely complex network of fractures, and the work presented here focuses on modeling these fracture networks to gain a better understanding of how hydraulic fractures perform in the Barnett. Over one hundred simulation runs were …

A Connectivity-based Hierarchical Model for Naturally Fractured Reservoir Simulation
… study on an actual offshore reservoir with four production wells and strong water drive, water cuts were observed to increase rapidly within a short period of time. The proposed model is capable of capturing such drastic flow dynamics accurately and efficiently, while the classic DP model, which …

Application of Polymer and Nanomaterials for Improving Heavy Oil Recovery
… which is a driving force for pushing oil toward production wells, reduces drastically in the early stages of oil production from underground resources. This leads to a significant decrease in oil production rate. To solve this problem, enhanced oil recovery (EOR) methods inject water, gas, or …
