Second, a thermal simulation model (based on the conceptual model) for CSD was calibrated to field data. Using thismodel, we conducted a parametric study to select the most impactful input parameters for machine...

Through synthetic case and field data testing, we demonstrated that the ML method is tolerant to data noise. Even at 15% of noise level, which is much higher than standard pressure...

... production enhancing effects caused by solvent injection. Dynamic allocation factor analysis was completed using real field data on a system with two injectors and fourteen producers. These injectors injected both water and miscible gas on regular WAG cycles. The results of the analysis were used...

... Abstract This paper presents a transient model to predict liquid loading in gas wells. This models enables the estimation of erratic or cease of production due to liquid loading using a simple but robust technique. This approach is supported by experimental and field data. The model described...

... flowing pressures and rate data is available. However, the method is for an idealized case that assumes constant production rate during pseudosteady-state (PSS) flow, which is not generally true for real wells. This paper extends that approach so that it can be used to analyze field data with variable...

... constitutive equations of orthotropic rock model. Using the proposed technique, minimum and maximum horizontal stress components can be determined corresponding to different pore pressure during the reservoir life. According to the field data, the new formulation increases the prediction accuracy when...

The three steamflood models selected were: a frontal advance model [Jones (1981)], a modified frontal advance model [Farouq Ali (1982)], and a vertical gravity override model [Miller and Leung (1985)]. Each model was somewhat modified to improve its ability for the prediction...
