Subject(s): Dissertation note: Thesis (MSc) - Cyprus International University. Institute of Graduate Studies and Research Petroleum and Natural Gas Engineering Summary: Well productivity is a crucial issue and strategy for field development, which is the production rate per unit of pressure drawdown. A well long-term performance behavior, or how it performs during steady state or pseudo-stationary state flow, is regularly correlated by petroleum engineers with the productivity estimation. The aim of this research is to determine the various horizontal well flow regimes and reservoir parameters needed to compute the productivity index, which as well as the productivity of the horizontal wells in the Mabruk oil field. Horizontal well drilling has importantly aided productivity and accelerated initiatives. The drilling of horizontal and vertical wells has grown greatly in recent years. Horizontal wells can be drilled parallel to bedding planes and along a formation strike, opening up more formation to the wellbore than vertical wells. After reviewing and applying several methods for calculating the productivity index under steady-state and pseudo-steady-state conditions to horizontal wells, compare the results with the actual productivity index to determine which best correlation produces the best results with the actual one. This study uses pressure build-up data from horizontal wells to give a technical procedure with field examples. This process applies two standard build-up analysis methods: (1) Conventional Procedure (2) Pan-System software simulation tool to determine the Productivity Index in Horizontal Wells. The actual Productivity Index results, indicate that the reservoir for the Mabruk oil field is anisotropic under steady-state conditions, supported the values produced by the Renard-Dupuy anisotropy approach.

Well productivity is a crucial issue and strategy for field development, which is the production rate per unit of pressure drawdown. A well long-term performance behavior, or how it performs during steady state or pseudo-stationary state flow, is regularly correlated by petroleum engineers with the productivity estimation.
The aim of this research is to determine the various horizontal well flow regimes and reservoir parameters needed to compute the productivity index, which as well as the productivity of the horizontal wells in the Mabruk oil field. Horizontal well drilling has importantly aided productivity and accelerated initiatives. The drilling of horizontal and vertical wells has grown greatly in recent years. Horizontal wells can be drilled parallel to bedding planes and along a formation strike, opening up more formation to the wellbore than vertical wells. After reviewing and applying several methods for calculating the productivity index under steady-state and pseudo-steady-state conditions to horizontal wells, compare the results with the actual productivity index to determine which best correlation produces the best results with the actual one.
This study uses pressure build-up data from horizontal wells to give a technical procedure with field examples. This process applies two standard build-up analysis methods: (1) Conventional Procedure (2) Pan-System software simulation tool to determine the Productivity Index in Horizontal Wells.
The actual Productivity Index results, indicate that the reservoir for the Mabruk oil field is anisotropic under steady-state conditions, supported the values produced by the Renard-Dupuy anisotropy approach.
