SUBJECT: Open-File Report No. OF-140
As we discussed, the following report from GeoChem
Laboratories, Inc. is to be placed in the Bureau Open-File:
OF-140 Hydrocarbon source-rock evaluation study, Hachita
Dome, Inc. No. 1 Tidball-Berry Federal well, Hidalgo
County, New Mexico, by Paul Tybor, GeoChem Laboratories, Inc., 1981, 13 p. (including 2 p. text, 8
tables, 2 charts)
Readers should note that the T-Max
("C) shown on Summary
Table I and on TableI1 is a laboratory determination made
during pyrolysis, and
is the temperatureat which volatile
components are cracked from the kerogen
in the sample. This
temperature usually ranges between
420'C and 550°C. Although
it is an indication of thermal maturity, this laboratory
measurement isnot anestimate of the maximum paleotemperature.

Dear Mr. Thompson:
of the organic geochemical analyses performed
Enclosed please find the results
on thirty-eight ( 3 8 ) well cuttings samples from the Hachita Dome Inc. No. 1
Tidball-Berry Federal well, located in Hidalgo County, New Mexico.
Upon arrival at GeoChem the samples were logged in under GeoChem Job Number
-001 to -038, and submitted to
1971, followed by the sample sequential number
the following geochemical analytical program:
