Summary This paper investigates the impacts of varied stimulated matrix permeability and matrix-block size on pressure behaviors flow regimes hydraulically fractured reservoirs using bivariate log-normal distribution. The main objective is assembling variance in these two parameters to analytical models derivative considering different porous-media petrophysical properties, reservoir configurations, hydraulic-fracture (HF) characteristics. motivation eliminating long-run discretization...

Abstract Horizontal wells with multiple hydraulic fractures have become a common occurrence in the oil and gas industry, especially tight formations. Published models assume are vertical symmetric. However, recent studies shown that asymmetric inclined respect to direction axis of wellbore. This paper introduces new technique for interpreting pressure behavior horizontal well fractures. The this model could be longitudinal or transverse, inclined, symmetrical asymmetrical. propagated...

Abstract Horizontal wells can greatly increase the contact area of wellbore and pay zone; so they are commonly applied in oil reservoirs to enhance production ultimate recovery, especially low permeability formations. The purpose this study is develop a technique for interpretation transient pressure based on dimensionless derivative. Type curve matching one techniques that be used interpret data horizontal finite reservoirs. Starting from very short extra-long wells, behavior has been...

Abstract Horizontal wells with multiple zonal isolations have become a common completion technique in the oil and gas industry. Sand problems, damaged zones, water or coning are main reasons for using isolators to sustain improve recovery. However, they certain effects on pressure behavior of horizontal wells. This paper introduces new analytical models studying effect this isolated zones. These been derived based assumption that reservoirs can be divided into multi-subsequent segments...

Abstract Horizontal wells with multiple hydraulic fractures have been used widely in the oil and gas industry. In published literatures, are assumed to be fully penetrating formations. Recent studies shown that partially more likely occur rather than The purpose of this study is formulate an analytical model describing pressure behavior a horizontal well fractures. This develop technique, based on derivative concept, for interpreting transient tests forecasting productivity well. were...

The objective of this paper is studying the impact hydraulic flow unit and reservoir quality index (RQI) on pressure profile productivity horizontal wells acting in finite reservoirs. Several mathematical models have been developed to investigate impact. These built based distribution porous media, depleted by a well, consist multi units different index. media are assumed be rectangular reservoirs having configurations wellbores may lengths. analytical describing regimes derived wherein...

Summary Reservoir performance of hydraulically fractured tight and shale-gas formations is affected by an extensive range parameters. Non-Darcy flow one these parameters, characterized a significant effect on near-wellbore pressure drop for horizontal wells near-fracture tips hydraulic fractures (HFs). develops in porous media when the velocity reservoir fluid becomes extremely high because continuous narrowing cross-sectional area convergence streamlines. As result, inertial forces could be...

Summary This paper introduces an approach for the impact of skin factor on decline curve analysis hydraulically fractured reservoirs. The objective is to consider this in production forecasting and ultimate recovery estimation. focuses reducing uncertainties that could be raised from history increasing accuracy predicted flow rates. It proposes easy promising tool applied confidently different oil- gas-producing wells utilizes rate-normalized rate derivative β behavior demonstrates a...
