Production Analysis and Enhancement in The Unconventional Tight Formations
… using multistage hydraulic fracturing for tight/shale oil and gas development. Analysis of the existing wells’ performance and development of production enhancement techniques are of critical interest for the improvement of the development efficiency in these formations. Production …

Performance Evaluation of Wells With Single and Multiple Fractures in Tight Formations
… been well understood since fluid flow in such tight formations can be completely dependent on the fracture network while the matrix only plays a source role. Therefore, it is of fundamental and practical importance to evaluate performance of a well with single and multiple fractures in a tight …

Fully Coupled Finite Element Model to Study Multiple Hydraulic Fracturing in Heterogeneous Tight Formations
… hydraulic fracturing process in heterogeneous tight formations and optimize the process by sensitivity analysis on parameters such as fracture number and fracture spacing during hydraulic fracturing operations.;In this study, a fully coupled finite element model was built to simulate multiple …

Numerical Simulation of pressure Transient Analysis in Tight Formation and Field Data Categorization and Typical Well Production Data Analysis
Low to ultra-low permeability tight oil reservoirs have recently become a significant source of hydrocarbon supply in North America. Production and pressure transient analysis of tight oil reservoirs is one of the most difficult problems facing a reservoir researcher because of the extreme …

Application of the Finite Element Method to Solve Coupled Multiphysics Problems for Subsurface Energy Extraction
… the existence of natural fractures in many tight formations. These natural fractures are likely filled with digenetic materials such as clays, quartz or calcite. In chapter 3, this study suggests that small cemented natural fractures can be opened by the induced tensile stress due to the …

Prevalence, persistence and consequences of microorganisms within oil field environments and mitigation strategies
… on a limited number of unconventional shale formations in the United States (e.g., the Marcellus Formation) and do not represent the geological conditions in other unconventional formations. This work focuses on less studied unconventional tight formations in the Permian Basin Formation …

Integration of Nano CT and SEM in the Characterization of Marcellus Shale
… knowledge of the geometry and topology of the tight shale rock. This study presents a simplified workflow in the study of the heterogeneity of shale rock sample by the combination of Nano CT imaging and Scanning Electron Microscopy imaging methodologies. The key components involve the uses of …

Hydrologic factors affecting the discharge of ground water in the Red River of the North Basin, northeastern North Dakota
… for estimating hydraulic conductivities in tight formations over short time periods.</p> <p>A ground-water flow model was used to investigate hydrogeologic factors affecting groundwater discharge. The thickness of the bedrock aquifers and confining units influences ground-water discharge. …

New Models and Analysis Techniques for Diagnostic Fracture Injection Tests
… however, their applicability is limited in ultra-tight formations due to prolonged test durations. To overcome this challenge, pump-in/flowback tests have been employed to expedite the testing process. However, the use of pump- in/flowback tests has declined due to uncertain and inconclusive …

Some contributions to the hydraulic characterization of fractured bedrock formations
… hydraulic characterization of fractured bedrock formations. It also presents the use of these tools in the development of the Conceptual Hydrogeologic Model for a fractured bedrock formation contaminated with chlorinated solvents. The field device was named the Multipurpose Packer System (MPS), a …

Geological Effects and Petrophysical Flow Unit Model for the Middle Bakken Member, South-East Saskatchewan
… problem remains that the Bakken formation is a tight system with very low reservoir qualities (permeability and porosity), which makes it difficult to allow reservoir fluid flow without introduction of a modern recovery technique to the natural reservoir drive energy. The relatively low …

Development of Scaling Crieteria for Waterflooding and Immiscible CO2 Flooding in Unconventional Reservoirs
… the unconventional oil resources (e.g., tight oil and heavy oil). Tight oil resources in Canada are mainly located in Cardium and Viking pools in Alberta, Bakken formation in Saskatchewan, and Western Canada Shale plays, respectively. Also, tremendous heavy oil resources accounting for …

Experimental investigation of proppant transport and behavior in horizontal wellbores using low viscosity fluids
… reservoirs. The reason for stimulating tight formations is to increase recoverable reserves and to accelerate production. This can be accomplished by placing hydraulic fractures in the targeted formations to allow the flow of oil and/or gas from the reservoir to the wellbore. These …
