Abstract Thousands of hydraulic fracture treatments have been monitored in the past ten years using microseismic mapping, providing a wealth measurements that show surprising degree diversity event patterns. Interpreting data to determine geometry and complexity fractures continues be focused on visualization patterns qualitative estimates "stimulated volume", which has led wide variations inconsistencies interpretations. Comparing energy input during treatment resultant released by events...

Abstract Hydraulic fracture monitoring with microseismic mapping is now routinely used to measure hydraulic geometry, location, and complexity, providing an abundance of information that can be essential optimizing stimulation treatments well completions. Although has added significant value in many different environments, we have yet fully utilize data. Significant details extracted from measurements that, when integrated other information, improve the characterization both reservoir...

Pesticides used in agriculture may cause adverse health effects among the population living near agricultural areas. However, identifying populations most likely to be exposed is difficult. We conducted a feasibility study determine whether satellite imagery could reconstruct historical crop patterns.

abstract Microseismic monitoring (MSM) of hydraulic fracture treatments is routine in North America and has added significantly to our understanding growth. The interpretation microseismic images advancing steadily, extracting more information from event patterns, temporal evolution, acoustic waveforms. increasing amount MSM provides significant opportunities improve stimulation designs, completion strategies, field development. However, the applications interpretations are many times...

Abstract The exploration and appraisal of low-permeability or unconventional hydrocarbon resources is significantly different than conventional reservoirs; more like appraisal, requiring pilot programs to test commerciality these plays prior embarking upon large-scale development (Hall 2007; Stabell et al. 2007), including the effect completion stimulation optimization (Haskett Brown 2005). One essential component reservoir hydraulic fracturing, which virtually all wells require. With...

The 3D printing of lung-equivalent phantoms using conventional polylactic acid (PLA) filaments requires the use low in-fill densities, which can produce substantial density heterogeneities from air gaps within resulting prints. Light-weight foaming PLA microscopic bubbles when heated to temperatures. In this study, expansion filament was characterised for two printers with different nozzle diameters, in order optimise flow rates required achieve a print printed at 100% density, without...

The aim of this study was to examine the impact social support on quality life (QoL) in patients with polyneuropathy. One hundred and fifty-four polyneuropathy were enrolled from a neuromuscular clinic. QoL Instrument Medical Outcome Study-Social Support Survey (MOS-SSS) used assess support, respectively. Disease severity clinical factors also assessed. Neuropathy had lower compared previously published normative sample (p < 0.0001) an MOS-SSS comparable other chronic disease. Social...

Summary In the oilfield industry, microseismic monitoring is widely applied to determine induced fracture network geometry and stress changes in reservoirs. The basic result usually a map of distribution events describing area influenced by injection/production reservoir fluids (e.g., hydraulic fracturing). As every microearthquake event (i.e., "dot" on map) processed individually, it has its own level location accuracy. To prevent any misinterpretations based with low accuracy,...

Summary Microseismic mapping's primary limitation is its viewing distance, which affected by noise, attenuation, and the intrinsic size of source event. In Rocky Mountains, required distances are often less than typical offset-well spacings, making accurate mapping difficult in many fields. A new approach to improving microseismic capabilities digitally stack signals from separate adjacent receivers obtain noise cancellation. This requires large numbers fast telemetry rates necessary data....

This study deals with mapping small scale discontinuities (hereinafter called rock fabric) on 3D reflection seismic data. Rock fabric and other properties such as stress anisotropy, intrinsic anisotropy of shales faults, play a crucial role in understanding the behavior fracture propagation during hydraulic stimulation. A new vector attribute is being introduced applied which picks up subtle data providing high level detail heterogeneity. has been linked to microseismic events acquired...
