Predominant material types shown on the log may contain different materials and the change from <br /> one predominant material type to another could be different than indicated. Descriptions on this log apply only at the specific locatio <br /> at the time of drilling and may not be representative of subsurface conditions at other locations or times. <br /> Project No. 77EL.14117.03.0502 Date 9/9/03 Log Of Well <br /> MW-8 SB-1.GPJ.
