Numerical Modeling of Boiling Due to Production in a Fractured Reservoir and Its Field Application
نویسندگان
چکیده
Numerical simulations were carried out to characterize the behaviors of fractured reservoirs under production which causes in-situ boiling. A radial flow model with a single production well, and a two-dimensional geothermal reservoir model with several production and injection wells were used to study the two-phase reservoir behavior. The behavior can be characterized mainly by the parameters such as the fracture spacing and matrix permeability. However, heterogeneous distribution of the steam saturation in the fracture and matrix regions brings about another complicated feature to problems of fractured two-phase reservoirs.

Application of Decline Analysis in Fractured Reservoirs, Field Case Studies
Decline curve analysis has some advantages over transient well test analysis in which it is not required to shut-in the well and also wellbore storage effects do not exist. Few studies have been done on decline curve analysis of naturally fractured reservoirs but there are even some limitations with available models. On the other hand well test could be expensive and in some operational conditi...

The significant increase in using reservoir simulation models poses significant challenges in the design and calibration of models. Moreover, conventional model calibration, history matching, is usually performed using a trial and error process of adjusting model parameters until a satisfactory match is obtained. In addition, history matching is an inverse problem, and hence it may have non-uni...

Production and injection of fluid may cause hydraulic fracture, shear fracture at crack levels, or re-activation of faults and existing discontinuities by reducing effective stress by changing the pore pressure and corresponding changes in the stress field. Therefore, the deformation of the earth, seismic occurred, the reactivation of discontinuities and the impermeability capacity of the rocks...
