... to emphasize one or more aspects of the displacement while neglecting other aspects for the sake of tractability. A parametric study is done, using a 3-D, compositional numerical simulator "VIP" in order to design the model and analyze the results and performance of miscible gas injection in Hassi Berkine...

... Abstract A systematic and efficient approach for well calibration against wellhead pressure has been developed and verified for two reservoir simulators. The new approach integrates the producing well conditions into the flow table generation step so that the well productivity can be matched...

..., from which mobility is obtained. The results of the technique are verified by history matching a field test with a 3-D near wellbore simulator, developed for gas formation testing modified for non Darcy flow effects. P. 183 non-darcy effect equation upstream oil & gas wireline formation...

... between the acid fluid loss and the rate of acid reaction with the formation versus the acid flow rate along the fracture. Acid conductivity experiments were performed with a unique conductivity instrument using limestone samples designed to simulate this complex process. Special emphasis was placed...

... to establish the gradients required for initializing fluid flow. From the standpoint of reservoir simulation, once the pressure distribution in the fracture grid is obtained at an iteration level, it is used as an external boundary condition to calculate the resultant perturbation in the matrix in the form...

... simulator (NEWS † ) was used to determine this shape factor (typically λ e = 0.9 to 1.2). Tight Zone Model In a previous paper (SPE 28449) a new "tight zone" model was introduced that uses the early time buildup data to determine formation permeability and tbe sandface buildup pressure. (4...

... ABSTRACT This paper presents the application of a new analytical simulator specifically developed for multilayer reservoirs. In this paper, we demonstrate how this analytical simulator can be used, the same way as a conventional numerical simulator, to history-match field pressure data...

... (slabbing). Unfortunately, our ability to deal analytically with heterogeneity is limited. Thus, it is necessary to use numerical methods to derive geometric factors for these complex, but realistic situations. A finite element simulator was used to study effects of heterogeneity on probe permeability...

The enhanced simulation will help manage the flood for optimum recovery. dissolution permeability spe 23957...

... the initiation and, therefore, intersection of the fracture with the wellbore. Sealed experiments suggest this may be accomplished by controlled wellbore notching techniques, and in some cases, high-density perforating procedures. Predictions made using a production simulator can be used to explore possible...

... ABSTRACT A substantial proportion of hydraulic fracture treatments are performed in formation and well completion settings conducive to the extension of multiple fractures, a process not adequately described by existing hydraulic fracture simulators. This paper introduces a procedure...

.... A compositional simulation study was undertaken to simulate complex mass transfer and composition changes. The study's objectives were to estimate the remaining condensate reserves and to determine an efficient depletion scheme including an optimum reservoir blowdown timing. After matching the past 23 years...
