Stress Sensitivity And Methane Adsorption In Shale Rock And Its Effects On Production

As we know,the extraction of gas from unconventional reserves in shale reservoirs is more complex than in conventional reservoirs.This is because of the ultratight and low permeability nature of these reservoirs.Shale reservoirs are generally characterized by complex structures and organic compounds that causes desorbtion.Shale gas been of outmost importance nowadays in most countries needs more sophisticated technologies in exploiting them.So in this research we are finding solutions that could help in extraction of gases from this tight shales,taking into account their matrix/fracture conductivity properties.So we are involved in experiments,simulations and interpolation of mathematical results using matlab for the mathemamatical analysis,simulation for model construction and curves for interpretation in order to estimate the amount of shale gas in rocks,we should be able to give an accurate estimation of the adsorbed gas on a dynamic production process.The difference between adsorption and desorption should be noted.Adsorbed gas on dynamic production process is imperative in predicting shale gas amount.In this research we are investigating the adsorption and diffusion which are important aspects in shale properties characterization.Experimental results estimates that the production from shale gas can be divided into shale gas expansion from inorganic matter and desorption.This research is based on adsorption,where production pressure(external pressure),temperature and particle diameter on a dynamic gas production process where considered based on the variable-volume method(VVM).We see delayed adsorption /diffusion model,and our interest is adsorption sequence and analysis.We see a measured dynamic experimental data and gas production calculations in curves these correlates to experimental results.Mathematical calculations with the use of mat-labs are derived to fit the research data,we have an inside that can help in studying adsorption during the process of shale gas production.We believe this can further be of paramount interest to during further researches that are aimed at ameliorating the technologies involved in shale gas production and subsequently impact recovery.
