Hilight Oil Field, Campbell County, Wyoming: Abstract

Tom Sprinkle1


Hilight Oil Field, located on the east flank of Powder River Basin, was discovered in February, 1969. Development of the field has been rapid and continuous until now there are about 240 producing wells spaced on 160 acre tracts. Oil and gas are produced from an isolated body of Lower Cretaceous Muddy sandstone penetrated at an approximate average depth of 9700 feet. Contours of Muddy marker indicate regional basinward or southwestward dip without structural anomalies. Isopachous analyses indicate an average net effective reservoir of 9 feet. This relatively low pore volume reservoir surprisingly has a history of high productivity. Original reservoir limit tests and recent pressure interference tests indicate a per well drainage area greater than 320 acres and that the field production boundaries are not established. No free formational waters have been produced from the Muddy reservoir.
