... model, we study practical algorithms of the pressure response, and use methods of numerical integrating and numerical inversion of Laplace transforms to compute typical curves for recognizing flow regimes and ape curve well test analysis. Based on these, this paper further gives expression equation...

.... Linear matrix algebra algorithms are preferred to iterative search techniques that are slower. One limitation of the existing linear matrix algebra algorithms is that they sometimes provide unrealistic values (negative or greater than one) of porosity and lithology fractions. Another limitation...

... Abstract This work presents the first equation-of-state (EOS) algorithm to computeminimum miscibility pressures (MMP) in hydrocarbon systems exhibitingthree-phase (L-L-V) equilibria. Previous efforts have been limited to systemsinvolving only two-phase equilibria. This work is particularly...

... Abstract An algorithm to compute pressure distributions in commingled reservoirs that are produced via complex completion systems is described. We show that single layer solutions for systems of interest can be readily combined to obtain pressure distributions in commingled reservoirs...

... post facto techniques have been developed for this purpose. This study examines presently available automatic history-matching algorithms reported; discusses the viability of each; and explores the fundamental weaknesses of two of the more promising methods. In addition, the existence of alternative...

... been mainly restricted to simple material balance algorithms. These material balance algorithms compare metered inlets into a pipeline system with metered outlets and generate an alarm whenever the difference between the two exceeds a preset alarm threshold. The selection of al arm thresholds...

... matrix symbolically, based on the structural patterns generated by D4 ordering. The reduced systemoccupies a single Quadrant of the original matrix, requiring fewer floatingpoint operations to solve. Execution time and memory requirements are compared between the Symbolic D4method and band algorithm...
