The present analytical method of evaluating
productivity index in vertical wells with partial completion does not
account for the effect of pressure drop due to partial completion.
The
purpose of this study is to develop analytical model for evaluating
productivity index (P.I) of vertical wells with partial completion,
where the effect of pressure drop due to partial completion is taken
into account and compare results with conventional methods.
The
partial differential equations were solved for both no-flow boundary and
constant pressure boundary systems in Laplace and Fourier Transform
domains before inversion to real time domain.
1.3 OBJECTIVES
The main objectives of this work are to:
· Develop analytical model for pressure behaviour in closed and constant pressure boundary systems
·
Develop an analytical model for evaluating productivity index of
vertical wells with partial completion for both closed-boundary and
constant pressure boundary systems taking into account the effect of
pressure drop due to partial completion
· Calculate shape factors and compare with the existing ones and
· Investigate the factors and parameters that influence or control productivity index.

ABSRACT - [ Total Page(s): 1 ]A new method for analysing productivity index (PI) on vertical wells is the main objective of this study. Well performance is often measured in terms of the well’s productivity which is dependent on a number of factors such as the reservoir’s configuration, the type of completion, petrophysical and fluid properties, formation damage, etc. The effect of partial completion is the main focus of making the productivity index analysis since almost all vertical wells are partially comple ...
