Instrumentation of dynamic gas pulse loading system

Description: The overall goal of this work is to further develop and field test a system of stimulating oil and gas wells, which increases the effective radius of the well bore so that more oil can flow into it, by recording pressure during the gas generation phase in real time so that fractures can be induced more predictably in the producing formation. Task 1: Complete the laboratory studies currently underway with the prototype model of the instrumentation currently being studied. Task 2: Perform field t… more

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas

Description: The Nevada Operations Office of the Energy Research and Development Administration (ERDA) has contracted with Petroleum Technology Corporation (PTC) to perform a gas stimulation program by chemical explosive fracturing (CEF) in the Canyon sands of the Val Verde - Kerr Basin of Sutton County, Texas. This lenticular tight sand deposit, underlying much of southwestern Texas, contains large volumes of natural gas. To date this formation has yielded only marginal amounts of gas because of its low po… more

A Strategy for Interpretation of Microearthquake Tomography Results in the Salton Sea Geothermal Field Based upon Rock Physics Interpretations of State 2-14 Borehole Logs

Description: We devise a strategy for analysis of Vp and Vs microearthquake tomography results in the Salton Sea geothermal field to identify important features of the geothermal reservoir. We first interpret rock properties in State 2-14 borehole based upon logged core through the reservoir. Then, we interpret seismic recordings in the well (Daley et al., 1988) to develop the strategy. We hypothesize that mapping Poisson's ratio has two applications for the Salton Sea geothermal reservoir: (1) to map the t… more

MOSSFRAC: An anisotropic 3D fracture model

Description: Despite the intense effort for nearly half a century to construct detailed numerical models of plastic flow and plastic damage accumulation, models for describing fracture, an equally important damage mechanism still cannot describe basic fracture phenomena. Typical fracture models set the stress tensor to zero for tensile fracture and set the deviatoric stress tensor to zero for compressive fracture. One consequence is that the simple case of the tensile fracture of a cylinder under combined c… more

Alternative oxidizers for strip coal mine blasting agents. [Including study of possible substitutes; 53 references]

Description: Since ammonium nitrate manufacture is dependent on natural gas, a shortage in natural gas could lead to a critical shortage in coal by limiting the availability of ammonium nitrate for blasting. The purpose of this study was to assess the future availability of ammonium nitrate and to evaluate the potential of alternative oxidizers not dependent upon natural gas for use in blasting agents. Increased storage capacities and rapidly increasing levels of relativey cheap imported ammonia appear to e… more

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas

Description: A proposed two-well stimulation test to be carried out in Sutton County, Texas is described. Work will be performed in the lenticular tight sand formation of the Val Verde-Kerr Basin to demonstrate the technical and economic feasibility of chemical explosive fracturing as a method of increasing gas deliverability in that formation. The purpose of the project's experimental design, which calls for the testing of two separate wells using different techniques, would be to obtain the maximum amount… more
