|dc.description.abstract||A study of the structure of the Lower Cretaceous Sparky sands
in the Saskatchewan part of the Lloydminster field has been made. All
available electric logs of wells in this part of the Lloydminster area
have been used to draw structure contour and isopach maps of the Sparky
oil zone, various stratigraphic cross sections and a contour map of the
Lower Cretaceous Mannville formation. A combination of differential
compaction, facies changes and regional tilting has resulted in structural
and stratigraphic traps suitable for the accumulation of oil and gas.
Structural traps result from differential compaction due to variations
in grain size of the Sparky sediments. Tilting of the interfingering
sands, silts and shales have formed stratigraphic traps.
A volumetric estimate of oil reserves in the Lone Rock pool was
made. Lack of pertinent production data limited the calculations and
many assumptions were necessary.
Temperature-viscosity relationships of some of the emulsified
and non-emulsified crude oils produced in the field were studied. These
relationships indicate a higher viscosity of the emulsion type crude as
compared with the viscosity of the same sample in its water free form.
A reversal of these properties occur below 60 degrees Fahrenheit. The
generally high productivity of the emulsion producing wells could be due
to the lower viscosity of the water free crude oil at reservoir temperatures
together with the possibility of a higher local permeability in the drainage
area. The emulsion is believed to have formed due to agitation by production
