Abstract The release of dissolved gas during the development gas-bearing tight oil reservoirs has a great influence on effect development. In this article, high-pressure mercury intrusion experiment was carried out in cores from different regions and lithologies Ordos Basin Sichuan Basin. objectives are to study microscopic characteristics porous throat structure these analyze flow resistance l...

Hydraulic fracturing horizontal well is the key technology of tight gas development. After fracturing, shows characteristics great difference in production energy and many factors affecting capacity. Therefore, taking 10 fractured wells JQ field Sichuan Basin as an example, comprehensively considering influence geological engineering factors, based on statistical analysis productivity laws vari...

In this paper, taking Block G in Canada as an example, combined with the data of working area, Pearson–MIC comprehensive evaluation method was adopted to optimize key parameters productivity. Based on analytic hierarchy process, weight each parameter calculated, grade index “sweet spot” divided, standard sweet spot established, and distribution superimposed finally depicted. The results show th...

The tight sandstone gas has huge objective reserves in China and great potential for development. Sulige field is the largest China. To prevent hydrates reduce surface pipeline pressure, downhole throttling technology been widely used field, Since wells are prone to liquid accumulation during production, installation of chokes makes phenomenon more complicated, traditional methods difficult sim...

In this study, the comparison of dry gas injection for vertical and horizontal production well scenarios are investigated by means conducting a reservoir simulation study tight condensate reservoir. order to conduct pattern has been defined. The selected is 420x420 m in areal extend 50 thickness. All necessary rock properties, fluid specifications together with compositions have determined cons...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

This study aimed to construct the hydrate three-phase equilibrium curves for two typical Iranian gas reservoir samples using a high-pressure visual cell. To do so, complete analysis of the reservoir fluids was obtained by different techniques of composition analysis i.e. gas chromatography (GC) and detailed hydrocarbon analysis (DHA). Using high-pressure visual cell the hydrate phase equili...
