HITCHNER EXPLORATION SERVICES LIMITED (HESL)

CONSULTING SERVICES PRICE SCHEDULE

January 2009.

(This price schedule is in effect until January 1, 2010)

 

ALL PRICES QUOTED IN UNITED STATES (US) DOLLARS

VISA and Mastercard through PayPal are accepted for payment

GST – Goods and Services Tax will be applied to all Canadian based orders

 

Every project is different, so HESL generally quotes cost and time estimates based on the specific objectives of the project, the available data and HESL work load at the time of the quote.  There are certain economies of scale for projects over 50 wells, again based on the available data and project objectives.  Prices include the use of the LOGMAP suite of well log analysis and mapping software.

 

EXAMPLE COST: Single well log computer assisted well log analysis – ONE ZONE DIGITIZED and ANALYZED with core data

Assumptions:

300-foot interval.  One main zone in complex lithology (carbonates)

8 curves digitized by hand; SP, gamma, neutron, density, acoustic, caliper, shallow and deep resistivity

1 – 60-foot core hand entered with depths, porosity, Kmax, Kvertical, K90, grain density

 

Digitization (minimum charge)                                                   $65.00

Depth correlation & general quality control                           $20.00

Core Entry and Depth Correlation                                              $40.00

Well Log Analysis                                                                        $350.00

Core to Well Log Comparisons                                                 $100.00

Net pay summaries with 2 cutoff sets                                       $40.00

Brief summary report of analysis results                              $150.00

                                                                                Total Cost:     $765.00

Client would receive

2 hard copies of the analysis summary plot. (see an example plot and net pay listing below)

1 copy of each net pay summary

1 copy of the core to well log crossplot correlations

1 copy of an analog (depth) plot of the core to well log analysis correlation (1:480 scale)

A brief summary report

 

Timing would be 3 days elapsed time, depending upon HESL workload, from receipt of the analysis request and the paper copies of the input data to be digitized and analyzed.

The image below represents a typical analysis summary plot provided for a single well analysis.  The display presents information in a columnar form versus depth.  The analysis summary plot is designed specific to the project and the information required of the client.  Typically, the raw input information is presented on the left with the analysis information on the right.  Generally, the more complex the interpretative data, the further to the right on the summary plot.

Where available, core data is overlaid with the corresponding interpretative data for comparison purposes.  In this example the core grain density, core porosity and core permeability are overlaid for comparison.

net pay cross plotGenerally, a cross plot of analysis porosity vs. analysis water saturation is used to determine net pay.

The net pay cutoffs are determined from inspection of the trends of the analysis porosity vs. analysis water saturation cross plot distribution.

This example shows the cross plot trends with a single porosity cutoff and a range of water saturation cutoffs.  Each of the ranges of water saturation are shaded a different color.

On a depth by depth basis, an analysis porosity - analysis water saturation data pair is cross plotted to determine which shaded area if any the data pair falls within.  If the data pair falls within a shaded area, the depth for that data pair is shaded to match the color of the shaded area. 

That same shaded depth column can be found on the analysis summary plot as well.  A small scale representation of the cross plot is found at the base of the data column on the analysis sumary plot.

Tabular net pay summaries are also generated based on the net pay cutoffs.

For every depth level that meets the cutoff criteria, cumulative porosity * thickness (PHI-H), cumulative hydrocarbon pore volume (HPV), cumulative thickness (H), cumulative permeability* thickness (k-H).

From these cumulatives, for a given interval, average porosity, average water saturation and average permeability can be determined.
