Explanation of Plate IV
| Section | |
|---|---|
| A-A' | Channel type in the old Pottawatomie Valley trend. 800-foot sand. |
| B-B' | Channel type with very sharply defined edges in the Garnett shoestring. The dry hole on the north side, with no sand. is only 225 feet from a producer with about 40 feet of sand. The base of the white-shale cover denotes the horizon of the top of the channel. 800-foot sand. |
| C-C' | Another section in the narrowest part of the Garnett' shoestring. The productive area is only 600 feet wide. 800-foot sand. |
| D-D' | A wider, shallower section in the Garnett string. The lower thin wedge may not be connected to the main body. In this part of the shoestring a thin sheet of sand is spread out several hundred feet in the horizon of the top of the channel. 800-foot sand. |
| E-E' | From a part of the Garnett field where the sand holds large amounts of gas because of being higher structurally. 800-foot sand. |
| F-F' | A channel section near the west end of the Bush City trend. The depressed and flat section of the top are features. The two end wells, which had showings of oil, were (hilled several years before the trend was discovered four miles farther west. 800-foot sand. |
| G-G' | The south edge of the Bush City channel showing thin sand extending from top of body. The two middle wells are another example of a dry hole and good oil well 300 feet apart. 800-foot sand. |
| H-H' | This section in the Bush City field has more irregularities than common but is sharply defined on the edges. 800-foot sand. |
| I-I' | The dry ho'e on the right might have been avoided by plotting the section of the sand outlined by earlier wells. The distinct rise in the bottom of the channel would have served as a warning of the nearness of the edge of the trend. Bush City field. 800-foot sand. |
| J -J' | A bar-shaped deposit in the Polkinghorn gas field. Perhaps some of the convexity is caused by settling. The body was disclosed by wells drilled to a deeper sand. 600- foot sand. |
| K-K' | Oil sand with bar-like outline from small pool north of Welda. The bottom of the deposit is sharply defined, but the upper part grades into broken sand and sandy shale. This is a part of the shallow-water or beach deposits of the south central part of the county that extend at a right angle to the channels. 800-foot sand. (See Fig. 5.) |
| L-L' | Section from the Colony-Welda gas trend. This section and sections O-O' and pop' have features that furnish contradictory theories of the origin of the sand body. (See discussion of origin under Colony gas field.) However, the sand body is believed to be a near-shore deposit of the beach-bar type. Attention is called to the lateral gradation into sandy shale on the east side. 900-foot sand. |
| M-M' | A thin, flat shallow-water or beach deposit from the Colony oil field. This is one of the widest of the restricted patches of sand in the Colony-Welda district. The clean-cut top and bottom, and lateral change into sandy shale, should be noted. The coal may be interpreted as indicating that the sand was laid down along a low, swampy land. 800-foot sand. |
| N-N' | A short section of beach (?) sand in the Colony district. 800-foot sand. |
| O-O' | The fingers of sand projecting several hundred feet from the main body are important features of this section from the Colony-Welda trend. The upward slant of the sand on the east side may be traceable to deposition on a sloping beach. 900-foot sand. |
| P-P' | This section from the townsite of Colony shows the shale break that separates the "first gas" from the "big gas." The sand body was penetrated over 100 feet in some of the wells. The abrupt thinning of the west side of the sand body is noteworthy. 900-foot sand. |
