SUBJECT: SFD Data Summary
I have completed a more in-depth review of SFD test flight data in conjunction
with evaluation of the Exploration Geosciences Northwest Montana Exploration
Evaluation which we recently acquired. During our test flight, we traversed 14
known oil and gas fields in southeastern Alberta and the adjacent portion of
northwestern Montana. These fields are denoted by letters A through P on the
test flight overlays and summary below. I have yet to acquire specific field and
production data for the Canadian fields traversed during the flight (including
fields A through II), such that reserve figures listed below are only estimates
based on my involvement in the area several years ago. The test flight data were
reviewed with Gordon, Kim, Doug, John and Ken at our Denver office on 13
January. Field data and SFD responses are summarized as follows:
Field Reservoir System Trap Type Oil/Gas Reserves SFD Response
- ----- ---------------- --------- ------- -------- ------------
A Cretaceous Stratigraphic Oil/Gas less than 1 MMBO Offset, Anomaly
B Devonian Structural Oil 2 MMBO Offset, Anomaly
C Devonian Structural Oil 5 MMBO Offset, Anomaly
D Devonian Structural Oil 5 MMBO Offset, Fault, Anomaly
E Cretaceous Stratigraphic Oil less than 1 MMBO Offset, Anomaly?
F Cretaceous Stratigraphic Oil 5 MMBO Offset, Anomaly
G Cretaceous Stratigraphic Oil less than 1 MMBO None; Turning
H Cretaceous Stratigraphic Oil less than 1 MMBO Offset, Anomaly?
I Mississippian/Cretaceous Structural Oil less than 1 MMBO None
J Mississippian/Cretaceous Combined Oil 150 MMBO Offset, Anomaly, Q2(x3)
K Cretaceous Stratigraphic Oil (S part of "J") Anomaly
L Mississippian Structural Oil 30 MMBO Offset, Anomaly
M Cretaceous Structural Oil less than 1 MMBO Offset, Anomaly
N Devonian Stratigraphic Oil/Gas 1 MMBO Offset, Anomaly, Q2
O Mississippian Structural Oil/Gas 100 MMBO Offset, Anomaly, Q1, Q2
P Cretaceous Stratigraphic Oil (crossing of "J") Offset, Anomaly
Including the SFD "miss" of Field "G" crossed during a turn, the SFD recorded
negative "offset" ("which usually indicates the structural beginning of a
field") and "anomalies" for 12 of the 14 fields traversed, representing a
coincidence rate of 85%. Altogether, traversed fields contain about 300 MMBOE of
proven reserves. The largest of these accumulations were characterized as having
better than average SFD anomalies as well having other "indicators" denoted as
Q1 (hydrocarbons) and Q2 (accumulation area). Consequently, the SFD appears to
have some capability in qualifying accumulation size. Also, the SFD appears to
relatively accurately delineate the edges of both structural and stratigraphic
hydrocarbon-bearing traps of a wide range of size (less than 1-150 MMBOE).

As discussed during our 13 January meeting, SFD anomalies recorded during our
test flight do not appear to result from gravity or magnetic phenomena except
---
where coincident with structures and hydrocarbon accumulations. Our test flight
also took us over a variety of terrain, and we traversed several river valleys
(certain of which were coincident with SFD anomalies), numerous pipelines (a
couple of which were coincident with SFD anomalies), and other surface phenomena
(including ranches and towns) which were "transparent" to the SFD.
The SFD also recorded other types of responses which appeared to be different
in some respects from offsets and anomalies associated with hydrocarbon
accumulations. Twenty such responses were reported by Pinnacle (most confirmed
by my flight log) as follows:
No. SFD Response Comments
- --- ------------ --------
1 Offset? edge of shallow gas field
2 Offset, Anomaly between two shallow oil fields; dry holes present
3 Offset dry holes present; shallow gas in vicinity; near end of turn
4 Offset dry holes present; shallow oil in vicinity
5 Offset, Anomaly dry holes present; 2 miles from shallow oil wells; turning
6 Offset, Anomaly, Faults? dry holes present; 2 miles from shallow oil wells; turning
7 Offset? dry holes present
8 Offset, Fault dry holes present; river valley
9 Fault? dry holes present
10 Anomaly no well control; turning
11 Offset, Anomaly dry hole with gas show
12 Change no well control; pipelines; Scapegoat-Bannatyne Trend
13 Offset, Anomaly no well control; 4 miles from shallow oil wells
14 Change no well control; Scapegoat-Bannatyne Trend
15 Anomaly, Fault no well control; river valley
16 Offset? dry hole in vicinity
17 Drop dry holes with gas shows in vicinity; turning
18 Offset, Anomaly edge of shallow gas field
19 Drop edge of oil and gas field; SFD in "saturating" mode
20 Anomalies, Faults eastern front of Disturbed Belt
Certain of these responses were clearly associated with turns in the flight
path. I recorded a couple of other SFD responses during turns which Pinnacle
apparently disregarded (it is their normal practice to discard all turn data).
Others were coincident with river valleys (fault controlled?), possible faults,
and known structural lineaments barren of hydrocarbons. Of these 20 recorded
"minor" responses, none would be considered as potential drilling prospects. I
plan on acquiring specific data on the Canadian fields traversed, with the
objective of competing test flight files.
