“…Feng et al also conducted depressurization and thermal stimulation experiments in porous media using one-dimensional systems [10,[42][43][44][45]. Based on the combined production methods, physical and mathematical models were developed to simulate hydrate dissociation [22,46,47]. Li et al employed TOUGH + HYDRATE simulator based on the geological data of the SH2, SH3 and SH7 site in the Shen Hu Area in South China Sea to simulate hydrate dissociation and water/gas production processes with only depressurization and with depressurization combined with thermal stimulation [48].…”

“…The depressurization method is impractical for normal operation since the operational pressure requirement is too high for transportation system. The method of depressurization and thermal method were utilized in hydrate exploitation recently [4,5]. The method of removing the water, using the methods of separation and dehydration was expensive.…”

In oil and gas exploration and transportation, low dosage hydrate inhibitors (LDHIs) are more favorably utilized to inhibit the formation of hydrates than thermodynamic inhibitors (THs) as a trend. However, there are no industrial products of LDHIs available domestically, and the corresponding application experience is in urgent need. In this paper, a combined hydrate inhibitor (HY-1) was synthesized after a series of reaction condition optimization, and its performance on THF hydrate inhibition was investigated using kinetic hydrate inhibitor evaluation apparatus with 6 cells bathing in air. The results show that when the reaction temperature is 60°C, the reaction time is 6 h, and the monomer: solvent ratio is 1:2, the product has the best kinetic hydrate inhibitor performance on THF hydrate. On these bases, the scale-up production of this combined hydrate inhibitor was carried out. Although the scale-up product (HY-10) performs less effectively on the THF hydrate inhibition than HY-1, it functions better than a commercial product (Inhibex501) during in-house tests. HY-10 was successfully applied to the gas production process. Field trials in northern Shaanxi PetroChina Changqing Oilfield Company (PCOC) show that 2 wt% of HY-10 is effective on natural gas hydrate inhibition. It is found through economic analysis that the use of HY-10 has obvious economical advantage over methanol and Inhibex501. natural gas hydrate, combined hydrate inhibitor, kinetic hydrate inhibitors, natural gas production Citation:Hu J, Wang Y H, Lang X M, et al.

“…Numerical approach to the problem has been attempted to address the real conditions existing in the reservoir and other operational issues. Gas production from hydrate reservoir by the combination of warm water flooding and depressurization was proposed by Bai and Li [7] which can overcome the deficiency of single production method. Sun et al [8] developed a onedimensional model of hydrate depressurization in porous media.…”

This work is based on modelling studies in an axisymmetric framework. The thermal stimulation of hydrated sediment is taken to occur by a centrally placed heat source. The model includes the hydrate dissociation and its effect on sediment bed deformation and resulting effect on gas production. A finite element package was customized to simulate the gas production from natural gas hydrate by considering the deformation of submarine bed. Three sediment models have been used to simulate gas production. The effect of sediment deformation on gas production by thermal stimulation is studied. Gas production rate is found to increase with an increase in the source temperature. Porosity of the sediment and saturation of the hydrate both have been found to significantly influence the rate of gas production.
