| Summary: | The use of relative permeability is an essential factor in reservoir engineering
knowing its capability to recognize the fluid flow characteristic in a reservoir,
several papers have been discussing this concept so far. Lack of core data and
special core analysis bring the engineer to use analog relative permeability curve
from another reservoir in reservoir simulation purposes.
This thesis is discussing how to develop relative permeability curve from well
historic production data, where the subject wells are horizontal and producing
from single reservoir. The iteration model is then developed as relation between
fractional flow to reflect the historic production data, simplified material balance
to reflect volume and saturation, and Corey equation to develop the relative
permeability curve.
The iteration proses is solved simultaneously and validated with production
history matching. Once the history is matched, the variables are accepted. The
reservoir characterization is then developed using oil and water exponent
variables which reflect the rock hydraulic flow, such as: grain size, sorting,
distribution and secondary porosity. |
