PNGE 352 - WELL LOGGING
HOMEWORK 3
( Due to: 31.03.2020 )
Look at the given Density Neutron logs and Resistivity logs of the same well. Answer the
following questions :
a) Where is the formation boundary ? (1 pt.)
b) What are the lithologies in the log section ?( 2 pts.)
c) Read porosity value for each meter in the depth interval between 1550 - 1565 m. by
using quick look interpretation method. (2 pts)
d) List Rt and Rxo readings from The Deep Lateral log and MSFL for the depth interval
between 1550 1565 m. ( 2 pts).
e) Calculate formation resistivity factor , F, for the same meters and list vs. depth.(1 pt)
f) Calculate Sw and Sxo values for the same meters and list vs. depth.( 2 pts)
Formation water salinity = 80 000 ppm.
Formation Temperature = 150 F
Mud filtrate salinity = 3000 ppm
NOTE: Use resistivity, salinity, temperature chart to find related resistivity values !
