Development Of Breakthrough Time Correlations For Coning In Bottom Water Supported Reservoirs

This research work mainly investigates the development and the behavior of cones (both water and gas cones) in oil reservoirs supported by strong aquifer, and from which analytical correlations are developed for quick engineering estimates of the time for water/gas cones to break into the perforations of the producing wells. The studies treated the cone development and breakthrough times in both horizontal and vertical well producing reservoirs and made analysis on them. The Ozkan and Raghavan (1990) method was employed as the base approach in the modeling of the cones; as well as their breakthrough times and then compare with that of Chaperon’s approach(1986) with both the horizontal and vertical well applied. The developed models were then run on field data, the results were graphically represented in both the horizontal and vertical well cases. Analytical correlations were then developed from the results obtained for breakthrough time estimation and compared with literature on example case. This work actually employs the dimensionless (or the normalized approach) system to curtail the units complexities and represent the results in a more generalized form. These analytical correlations can be leveraged on to plan better future recompletion strategy as they provide an engineering estimate of when water breaks into the production wells.

CHAPTER ONE - [ Total Page(s): 2 ]STABLE CONE:If a
well is produced at a constant rate and the pressure gradient in the
drainage system have constant, a steady state condition is reached, if
at this condition, the dynamic forces (viscous forces) at the well are
less than the gravity forces then the water or gas cone that has formed
will not extend to the well .Moreover, the cone will not advance nor
recede, thus establishing what is known as stable cone.UNSTABLE CONE:Conversely,
if the pressure in the system is in ... Continue reading---
