We performed an integrated study of multistage hydraulic fracture stimulation of two parallel horizontal wells in the Bakken Formation in the Williston Basin, North Dakota. There are three distinct parts of this study: development of a geomechanical model for the study area, interpretation of multiarray downhole recordings of microseismic events, and interpretation of hydraulic fracturing data ...

Abstract In this study, we investigate numerically the hydro-mechanical behavior of fractured crystalline rock due to one five hydraulic stimulations at Pohang Enhanced Geothermal site in South Korea. We use commercial code FracMan (Golder Associates) that enables studying coupled processes media three dimensions combining finite element method with a discrete fracture network. The software is ...

The United Downs Deep Geothermal Project (UDDGP) is designed to utilize a presumably permeable steep dipping fault damage zone (constituting the hydrothermal reservoir in very low permeability granitic host rock) for fluid circulation and heat extraction between an injection well at 2.2 km depth (UD?2) production 5 (UD?1). Soft hydraulic stimulation was performed increase of reservoir. Numerica...

In 1947, Stanolind Oil & Gas performed the first experimental hydraulic fracturing treatment in the Hugoton field in southwestern Kansas, USA. Since then, E&P companies have employed this reservoir stimulation technique extensively to enhance or prolong well productivity. Indeed...

Measurements of attenuation anisotropy can provide valuable information for reservoir characterization and monitoring. Here, we analyze cross-hole data generated by perforation shots fired in a horizontal borehole to induce hydraulic fracturing in a tight gas reservoir. The spectral-ratio method is applied to pairs of traces to set up a system of equations for directionally-dependent effective ...

Efficient use of water, particularly in the western U.S., is an increasingly important aspect of many activities including agriculture, urban, and industry. As the population increases and agriculture and energy needs continue to rise, the pressure on water and other natural resources is expected to intensify. Recent advances in technology have stimulated growth in oil and gas development, as w...
