Eleven wells were drilled in 1992 by 5 oil companies (Figure 6A). Only
Axem/Murfin used the integrated approach of soil gas geochemistry with
geology and seismic to select well locations. The locations of the wells
drilled in 1992 are shown on Figure 6A. An ethane magnitude contour map
(Figure 6B) illustrates the geochemical basis of Axem/Murfin decisions
in selecting well sites. The following is the order in which the 1992
wells were drilled:
1 In April and May 1992, MW Pet. drilled two Morrow dry
holes with the Brewer #24-2 and Sell #13-31 wells. Both wells were 4000-foot
step-outs. Both well locations are in areas of background soil gas concentrations.
No further wells were drilled by this company in the this area
2 In August 1992, Axem/Murfin drilled their first well
and completed the Coyote # 1 as a Morrow oil well (Figures 6A and 6B).
This was a very significant well in that it was a 4700-foot step-out extension
for Moore-Johnson field. The well location was supported by a strong soil
gas anomaly. The well confirmed the conceptual model established by integrating
geochemistry with geology and geophysics.
3 Duncan Energy completed two direct offsets in October
and November to the Amoco Brewer #1 and #2 producing Morrow wells. These
two wells were only 1500-foot offset locations.
4 In November 1992, Axem/Murfin completed two Morrow
wells with the Wendleburg #1-11 and Blackbird #1 wells. The Wendleburg
#1-11 location was supported by a strong soil gas anomaly.
5 In December 1992, HGB Oil completed the Brewer #1 as
a Morrow oil well. This location had been proven by the preceding surrounding
wells to the west, east, and south.
6 HGB Oil, Yates, and Duncan Energy each drilled a Morrow
dry hole in Colorado attempting to extend field production updip and to
the west. There were now five dry holes in Colorado to the west of the
field. All five well locations are in areas of low magnitude soil gas
data.
By the end of 1992, Moore-Johnson field had produced 512,714 BO.
