Abstract:
Gas hydrates are white compounds with crystalline and non-stoichiometric form. Formation of it occurs in the presence of water at low temperatures and high pressures with Methane, Ethane, Propane, Isobutane and number of other gases. A cage-like crystal structure gets formed through hydrogen bonding around the entrapped gas molecules.
The removal of methane from gas hydrates economically and environment friendly is necessary. The Methane gets produced from Gas Hydrates dissociation which occurs inside the marine sediment after applications techniques such as Depressurization, Chemical Inhibitor Injection, Thermal stimulation etc. So, there is need to predict the suitable technique which fulfil the requirement of producing Methane by avoiding hydrate reformation.The effectiveness of Dissociation Technique is dependent on the reservoir properties of Gas Hydrates. The behaviors of different chemical inhibitors in the reservoir can be studied through simulation. The simulation on the properties of National Gas Hydrate Programme (NGHP)-02 sites is carried using simulation on T+H. Therefore, the main objective of this thesis is to do comparative study between Inhibitors and 1TbS Test file; and then among Different Tests files namely 1P, 1P_ice, 1_Pk, 1T, 1_TbS and 1_TbSk with parameters on the selected site properties respectively. The cellulose content percentage in wheat straw sample is also calculated.
