The Productivity Equation for a Horizontal Well in a Fault Block, Rectangular Reservoir With Multiple Wells Flooding

It is suitable and practical as well as economical for many oilfield to deploy irregular patterns vertical injection and horizontal production well group due to the geology complexity (e.g., as fault, structure), development cost and field operation of the actual reservoir. The authors present steady state productivity equations for a horizontal well in a fault block, rectangular reservoir with multiple wells flooding. The new equations, which are based on potential-flow theory, conformal mapping method, and superposition principle, are simple, accurate, and easy to use in field practice. In addition, the authors also give corresponding methods for calculating productivity. They conduct a comparison analysis by combining the practical field data, and this method can be applied to field productivity predication.
