1. For the log No. (Excel data included), interpret the log from top to bottom:
a) Identify the zones (either by change of lithology or fluid)
b) Calculate the water saturation for the dean zone foot by foot and plot the
log track format similar to the examplei cross plot lecture notes. Report a,m
values and include the Pickett plot in your final report. For calculating should use
the Pickett plot spreadsheet and assume n=2, Deep resistivity reads Re and PHIX is
porosity Hint: For the Pickett plot guessing values, start with m=2 a=1.
c) Identify the lithology zone by zone from the top to the bottom of thelog. Use the N-D
spreadsheet and include t in your report gr/cm³).
d) lithe water saturation cut off 50% what interval should be perforated?
e) lithe BVWi= 0.07 which HC intervali: water free zone?
f) the cut off value for BVW is 0.12, which interval should be perforated? Compare it
with the results part "d". The smaller one the Net pay! Report the Net pay
2. For the following log -log plot which includes depths from water bearing zone:
a) Calculate R. and cementation factor Assume a= and n=2.
b) Plot the lines S.=75% S.=50% and Sn=30% lithe Sn cut-off 50% circle the reservoir
in this question you are NOT allowed to use any spreadsheets Plot the lines on the given
graph and show your calculations for each line.
Based the available use the appropriate crossplot and fill out the following table
a) For Por-11 and Lith 6crossplots, calculate the percentage of sandstone, Limestone and
b) Using chart Por-11, find the porosity of the zones.
In this question you are NOT allowed to use : any spreadsheets Plot the points on the proper
cross plot and show your work on the crossplot calculations related each cross plot.
1) Show your calculations. lithe same calculation repeated, just show one example of the
Include the charts being used and show your work on those charts
3) Submit your HW only ir PDF or MS Office word format.
