Understanding hydraulic fracture propagation events would enable operators to estimate the geometry, understand formation/fracture interactions, and total microseismic cloud. This paper introduces a new method for understanding dynamic using signal processing technique. Detection of event continuous wavelet transform (CWT) is used train deep learning model with predict this cloud every job. The same formation.

Abstract The aim of this study is to investigate the potential Continuous Wavelet Transform (CWT) as a mathematical tool for improving understanding hydraulic fracture propagation mechanisms and evaluating interactions between fractures formation. examines one CWT techniques: normalized scalogram technique propagation. However, implementation these techniques requires calibration using observed measured variables, such microseismic events. To overcome obstacle, micro-seismic events, pressure...

The diagnostic fracture injection test (DFIT) is widely used to obtain the closure pressure, reservoir permeability, and pressure. Conventional methods for analyzing DFIT are based on assumption that a vertical well drilled in ultra-low permeability reservoirs with potential multiple closures but fails consider horizontal wells. There still significant debate about rigorousness validity of these techniques due complexity hydraulic opening process assumptions conventional detection methods....

The article discusses the new technique for fracture closure pressure detection using continuous wavelet transform (CWT). study focuses on calibrating CWT and comparing it with different techniques detection. According to article, traditional methods identifying of hydraulic fracturing operations are based assumptions that can conflict one another, resulting in greatly varying approximations duration. To address this issue, employs a set diagnostic injection tests utilize Step-Rate Injection...

Plasma stimulation is a form of waterless fracturing as it requires that only the wellbore be filled with an aqueous fluid. The technique creates multiple fractures propagating in different directions around wellbore. intent this paper to present experimental and numerical investigation degree competitiveness plasma hydraulic fracturing, especially case stimulating tight formation. Several cases were run experimentally. samples included limestone sandstone investigate rock types. In...

Formation fracturing is the method of choice for developing shale oil and gas reservoirs that constitute a gigantic resource in U.S.A. many other countries but are characterized by low permeability nano-Darcy range. The production Texas has increased about 5 million B/D 15 years as result exploitation massive multistage hydraulic fracturing. mathematical modeling this process complex can be approached several ways. This paper first gives concise description carried out Texas. Included ranges...

A need for a reduction in energy intensity and greenhouse gas emissions of bitumen heavy oil recovery processes has led to the invention several methods where mass-transfer-based terms cold or heated solvent injection are used reduce viscosity rather than steam injection. Despite extensive numerical experimental investigations, field results not always aligned what is predicted unless history matches done. These discrepancies can be explained by investigating mechanisms involved mass...

Abstract The present experimental and theoretical investigation was concerned with the oil recovery sweep efficiency obtained in a two-dimensional polymer flood. Both single phase (brine displaced by solution) two-phase (oil brine polymer) displacement studies were conducted. mathematical models developed utilize concept of resistance factor, its variation throughput past any given point flow pattern. validated on basis good agreement observed between predicted results. Experimental carried...

Abstract Although closure detection has a crucial role in hydraulic fracturing operations, significant debate surrounds the various methodologies to determine its value. Several competing have been presented literature that sometimesyield significantly different estimates of pressure and time. The conventional techniques rely on assumptions may be or even contradictory. continuous wavelets transform technique is data convolves and/or temperature using short wavy signal called "wavelet"....

Abstract Well test analyses are normally performed using a combination of type-curve and semi-log methods for determining reservoir rock properties such as permeability (transmissivity) or near-wellbore damage. Unfortunately, calculated values these can vary substantially between the two methods. Conducting history match often eliminate ambiguity but it fails to identify best answer from multiple solutions. A practical approach improving characterization is introduced in this paper which...
