DEVELOPMENT OF GENERALIZED WELL SEMI-ANALYTICAL CONING MODELS

ABSTRACT

The development of generalized well semi-analytical coning models is a significant research area in the field of petroleum engineering. Coning refers to the undesirable production of fluids from a reservoir due to the presence of a wellbore. It occurs when the pressure drawdown around the wellbore causes the fluid to cone towards the well, leading to a decrease in reservoir performance and potential damage to the reservoir.

Generalized well semi-analytical coning models aim to provide a comprehensive understanding of coning behavior under various reservoir and well conditions. These models incorporate analytical equations, numerical methods, and empirical data to predict and analyze fluid coning phenomena accurately.

The development of these models involves several key steps. Initially, researchers gather data on the reservoir properties, such as permeability, porosity, and fluid properties. They also consider the wellbore characteristics, including wellbore radius, completion type, and production rates. This data is crucial for calibrating the coning models and validating their accuracy.

Researchers then apply mathematical and analytical techniques to formulate equations that describe the fluid flow behavior in the reservoir and around the wellbore. These equations consider parameters such as pressure, flow rate, and fluid saturation. Various assumptions and simplifications are made to make the models computationally tractable while maintaining a reasonable level of accuracy.

Next, numerical methods are employed to solve the formulated equations. These methods can include finite difference, finite element, or finite volume techniques. The numerical solutions provide detailed insights into the fluid flow patterns, pressure distribution, and coning behavior near the wellbore.

To ensure the reliability and applicability of the coning models, researchers validate their results using field data and experimental observations. This validation process helps to refine the models and improve their predictive capabilities. It also allows for the identification of limitations and areas for further enhancement.

The development of generalized well semi-analytical coning models has several practical implications. These models assist in optimizing well placement, completion design, and production strategies to mitigate coning-related issues. They enable engineers to make informed decisions regarding well spacing, perforation strategies, and production rate optimization to maximize reservoir performance and minimize coning effects.

In conclusion, the development of generalized well semi-analytical coning models is a valuable research endeavor in petroleum engineering. These models provide a systematic and comprehensive approach to understanding and predicting fluid coning behavior in reservoirs. By incorporating reservoir and wellbore characteristics, mathematical formulations, numerical methods, and validation processes, these models enhance the decision-making process and help optimize production strategies for improved reservoir performance.
