RESISTIVITY
AND RESERVES
(limited
porosity
data
available
for
area
of
interest)
Preanalysis data preparation
- Input of formation tops and
bottoms
- Merging of SWC or Conventional
Core with logs
|
Clay volume and Porosity calculation
- Minimum Vshale calculations
from GR, SP, and R and R SQ
- Determining Phi Maximum for
each zone
- Generate Frequency
distribution Plots of Core data
- Calculate density/neutron
cross-plot porosity
- Utilization of any other
porosity data
|
Model Comparison to standard interpretation techniques
(Pilot Study)
-
Comparison of
GNP HPV, Sw, and Phi to standard calculations of HFT, Sw, and Phi on
wells with porosity data
|
Sand Quality Computation (Pilot study)
- Determine Rw from RWA,
Pickett Plots or other sources
- Input of Client defined
models/equations
- Determination of Sw
irreducible through Cores and standard Archie calculations where
porosity available
- Selection of Conductivity
Clean and Conductivity hard shale values
|
Final calculations
- Calculate HPV(Hydrocarbon Pore
Volume), total Phi, total Sw
- Diagnostic log presentation of
Vshale, PHI total, Sw. Core K, PHI, and saturation values will be
plotted on the log when available
- Annotate the log with
production, test, and geologic information as defined by the customer
|
Summation reports
- Spreadsheet presentation
includes for each zone
- Weight averaged porosity and
Sw
- Gross, Net and Pay Sand
counts
- Cumulative Hydrocarbon feet
- Pick cutoffs for Vshale, Sw,
and PHIE
- Summations by well and zone
- Final log presentation
- Output data in Customer
defined media. (i.e. Diskette, CD Rom,etc.)
