Two sand intervals, Sand No. 3 and Sand No. 1, were independently tested during our program. Sand No. 3 was the deepeer zone and was tested first. A gamma ray--neutron log of these zones, and the intervals perforated, are shown. The gamma ray log run in 1968 showed Sand No. 1 to be a fairly uniform section with few shale breaks and our original plans were to perforate the entire interval. After obtaining the more recent GR log big shale breaks were shown to exist throughout the zone, so a smaller interval was selected. A net sand thickness of 48 ft. was used for Sand No. 3 and 30 ft. for Sand No. 1. There was no data available to indicate whether these zones became thicker or thinner away from the wellbore; therefore, these values were used as net thickness in the reservoir calculations. The procedure used to perforate the two sands were different. Both were perforated with 0.33 inch jets at a density of 4 shots per foot; however, Sand No. 3 was perforated in two runs using a stand-off gun, whereas Sand No. 1 was perforated in one run using a centralized gun with the jet density being 4 shots per foot but oriented alternately at 180 degrees.
