Acidizing, a very common stimulation process, is generally initiated when near wellbore formation damage causes a reduction in the productivity of an oil or gas reservoir. The ultimate goal of acidizing is to improve the near wellbore permeability and hence it is required that the permeability change due to the process be evaluated. Predictions of permeability alteration can be made before starting a project, and also, the altered permeability can be stated after the process. This paper describes a computer model that predicts the permeability alteration of an acidization process. A complete computer package is developed which consists of iterative optimizations and huge computations in order to simulate the permeability and porosity changes at each point during the process and, finally, to predict the post process permeability. As the optimization algorithm. a genetic algorithm which is somewhat more effective than the conventional ones, is used in the computer model. Thus a solution technique for a permeability prediction problem in acidizing is presented in this paper with all its uniqueness of type and effectiveness in practical applications.

Genetic algorithm for estimating multiphase flow functions from unsteady-state displacement experiments Akın, Serhat (1998-04-30) Relative permeability and capillary pressure are the primary flow parameters required to model multiphase flow in porous media. Frequently, these properties are estimated on the basis of unsteady state laboratory displacement experiments. Interpretation of the flood process to obtain relative permeability data is performed by one of two means: application of frontal advance theory or direct computer simulation. Application of frontal advance theory requires a number of experimental restrictions such that th...
Genetic algorithms for optimizing the remediation of contaminated aquifer Gumrah, F; Erbas, D; Oz, B; Altintas, S (2000-11-01) Produced water constitutes a large amount of waste fluids during the production operation of an oil field. Underground injection for disposing the wastewater from hydrocarbon production is an engineering problem due to the possibility of leakage of injected pollutant material from receiving medium to a drinking water source. This paper describes a method for optimization of polluted aquifer remediation design using one of the artificial intelligence optimization methods, namely Genetic Algorithms (GAs). As ...
Numerical modeling of counter-current spontaneous imbibition during underbalanced drilling Naseri, Masoud; Sınayuç, Çağlar (2012-09-10) Mud solid and filtrate invasion are the most common causes of formation damage during overbalanced drilling (OBD), which is a method of drilling in which the wellbore pressure remains greater than formation pressure. During the past ten years, underbalanced drilling operations (UBD), which can be defined as a drilling method in which the wellbore pressure is less than formation pressure, has been growing due to their applications such as prevention of lost circulation, reduction of filtration lost in natura...
DESIGN AND MODELLING OF A HYBRID PRESSURE REGULATOR Gürfidan, Mehmet Gökalp; Yazıcıoğlu, Yiğit; Department of Mechanical Engineering (2022-9-14) Pressure regulator is used for regulating high upstream pressure to required low downstream pressure. It is especially an important component for space applications where an accurate pressure control is vital, and failure to do so can cause mission failure. In this thesis a novel pressure regulator design is modeled that eliminates the inherent steady state error of purely mechanical pressure regulator by introducing cascaded electromechanical actuator. Dynamic components of the proposed hybrid pressure reg...
The Application of Water-flood Technology for Different Oil Fields Kök, Mustafa Verşan (Informa UK Limited, 2011-01-01) Water-flooding is perhaps the most common method of secondary recovery, in which water is injected into the reservoir formation to displace residual oil. The water from injection wells physically sweeps the displaced oil to adjacent production wells. In this study, three different fields from different locations were studied for a possible water-flooding operation using software. Through the results obtained from the application, certain predictions were obtained about the water-flood performance of the oil...
