... the numerical simulation problem less appealing and the estimation of properties more non-unique, especially for Pressure Transient Analysis (PTA). Understanding the circumstances under which total flow properties dominate over individual-phase flow properties prompts the implementation of a singlephase type...

... Abstract Pressure transient analysis (PTA) is traditionally used to characterize well and reservoir parameters from well tests based on shut-in periods. PTA was widely used for reservoir management and decision making before reservoir simulation became the main tool. Presently more and more...

... Abstract This research work presents an investigation on a wave physics approach to pressure transient analysis. It is hinged on the view that a pressure transient phenomenon has an associated wave behaviour. A Reservoir pressure transient partial differential equation is developed by importing...

... Abstract The second largest oil spillage in Norwegian petroleum history occurred on December 12, 2007, when the Statfjord A offloading system ruptured. Results of numerical simulations of pressure transients in the off-loading system are presented. Of particular interest is the influence...

In order to keep the execution time of this algorithm within an acceptable range, the perturbation on the pressure transient due to a local permeability heterogeneity is determined in the form of an analytic influence function.

... ABSTRACT Pressure transient behaviors in a naturally fractured reservoir with unsteady state matrix to fracture flow (transient interporosity flow) are simulated using a multiple interacting continua (MINC) method. The numerical method is verified by comparison with the analytical solutions...
