Abstract

Shale is a growing prospect in this world with decreasing conventional sources of fossil fuel. With the growth in demand for natural gas, there is impending need for the development of the robust model for the flow of shale gas (Behar and Vandenbroucke in Org Geochem, 11:15–24, 1987). So the major driving force behind the working on this major project is the unavailability of desired models that could lead to enhanced production of these wells and that too efficiently. This model mainly includes the movement of shale gas from tight reservoir through the conductive fractures to wellbore and production model of the decline in pressure inside the reservoir with respect to time. This result has been further compared with the help of MATLAB so as to obtain a complete pressure-derived model. The result shows the applicability of this in the real-life projects where it is difficult to model the fractures and obtain the flow rate with them in fractures and how to set the production facilities becomes a question.

Highlights

Shale is known as fine-grained, clastic sedimentary rock
As per the current methodology, the work appears to be promising and will yield a great model of the shale which will be completed from every end and the further study will be revolving around such models which will be founding pillars of the researches
Our project is stood on mainly two pillars: one pillar is of the MATLAB work for solving the set of nonlinear PDE’s and the other pillar is the simulation results

Summary

Introduction

The molecule size of shale is little which makes the interstitial spaces likewise little. They are minute to the point that oil, regular gas and water experience issues. Shale gas is viewed as an alleged ‘‘unusual gas,’’ together with ‘‘tight gas’’ with low permeability and ‘‘coal-bed methane’’ (CBM). While both traditional and capricious stores contain normal gas, it is the more intricate generation strategies that recognize the ordinary and offbeat store (Gong et al 2011). As indicated by the accessible sources, India has around 300–2100 tcf evaluated gas setup in Indian shale gas bowls which is much bigger than stores that are accessible in Krishna–Godavari (D 6) Basin (Swami et al 2013)
