LOGS COMPILED 
Logs are indicated by abbreviations 
DRIL a drillers log is available 
SAMP a sample log is available 
LOCATION 
Location is given by latitude and longitude as plotted on 7i and 15- 
minute quadrangles and by quadrangle section as subdivided into ninths 
and labeled from A to I. 
LATITUDE 
Number of feet north (N) or south (S) of the latitude given in degrees 
minutes, and seconds. 
LONGITUDE 
Number of feet east (E) or west (W) of longitude given in degrees, min' 
nutes, and seconds. 
DATE COMMENCED 
Date of drilling commencement. 
DATE COMPLETED 
Date of drilling completion. 
DATE ABANDONED 
Date of well abandonment. 
ELEVATION 
Either DERRICK FLOOR or KELLY BUSHING in feet. 
GRND ELEV 
Ground elevation. 
ELEV TYPE 
Indication of how the ground elevation was determined.

ROTARY TOOLS 
Top and base of drilling by rotary tools. 
15 MIN. QUAD. 
The name of the fifteen-minute quadrangle on which the well has been 
plotted by the given latitude and longitude. Also, the ninth of the 
quadrangle is given after SEC. 
7-1/2 MIN. QUAD. 
The name of the Tlr-minute quadrangle on which the well has been plot¬ 
ted by given latitude and longitude. Also, the ninth of the quad¬ 
rangle is given after SEC.
