Front Cover Illustration
Synthetic model of the Permian on the western edge of the Permian Basin, based on outcrop data from the Guadalupe, Brokeoff and Sierra Diablo mountains. The model shows the general stratigraphic setting the field trip will visit in the Wolfcampian, Leonardian, Guadalupian and Ochoan.  This complete strati­ graphic section of the Permian is the result of over a decade of work by geologists from the Texas Bureau of Economic Geology.  Additional data has been from geologists in the oil industry, federal and state surveys, and academic institutions. Data density and stratigraphic resolution is greatest in the Guadalupian. Latest research on the Brushy Canyon basin fill has not been incorporated.

The Red Bed map, finished in October, 1924, by geologist O.C. "Kip" Harper.  The isopach map is of Triassic red beds and was based on five wells, scattered outcrops, and water wells from ranches.  This was probably the first map that showed a thinning of red beds over a buried positive feature, the Central Basin Platform.  In the following year, 1925, several successful wildcat wells were drilled along the flanks of the trend.  These discoveries produced large volumes of West Texas intermediate crude from Permian carbonates.  Reprinted by permission from the Permian Petroleum Museum, where the original map is on display.

Editors Preface

This field trip will have the opportunity to visit the classic Permian outcrops of West Texas and south­ eastern New Mexico. It will require visiting two separate mountain ranges, the Sierra Diablo and Guadalupe mountains, and viewing the Ochoan evaporite section via cores.
The field trip will first be based out of Van Horn, Texas, and visit Wolfcampian and Leonardian sections in the Sierra Diablo mountain range, with most time spent in Apache Canyon.  The field trip will transfer to Carlsbad, New Mexico, to visit Guadalupian sections in several locations along the Algerita and Shattuck Valley escarpments, Last Chance Canyon, and McKittrick Canyon.  Ochoan evaporites can only be viewed at the state line outcrop, just inside New Mexico.   This interval will be studied via a core workshop  in Carlsbad.
Ochoan evaporates provided the regional seal over the entire Permian Basin.   Oil and gas that was generated and expelled from various source rocks was trapped within the Permian Basin by this overlying evaporite section.
It is no wonder that, through 1984, five percent of the world’s total oil and gas production has been from the Permian Basin.  We hope that each field trip participant will enjoy the field trip as much as we have enjoyed putting it together for you.  We sincerely thank our great group of field trip leaders, all of the field trip committee members, and the executive committee of the West Texas Geological Society for their help and support of this field trip.

Presidents Message

"And some rin uphill and downdale,
knapping the chunky stanes to pieces wi' hammers,
like sae many road-makers run daft.
They say it is to see how the warld was made!"
Sir Walter Scott
St. Ronan's Well, 1824

It is a great pleasure to welcome you to the West Texas Geological Society Y2K Field Trip!
Bob Lindsay and his crew are to be congratulated for putting together a "millennium-class" event.  This
will be the first field trip to review the entire Permian section of West Texas and southeastern New Mexico: Wolfcampian, Leonardian, Guadalupian,  Ochoan.  Bottom to top.  The whole deal.
All of the sections we will visit have been re-studied over the past few years with sequence stratigraphic methods.  Many of these outcrops will serve as excellent subsurface equivalents, and the poster session and core workshop will specifically review subsurface analogs.
This will bring immediate, practical benefits to our work as we continue to focus more and more on developing known reservoirs.   Modeling flow units has become one of our most important techniques to coax more oil from dwindling reserves.  What better way to learn and understand what a "flow unit" really is than to see it in the field?
The premise behind all this, of course, is that "the best geologist is the one who has seen the most
geology!'   Whether you agree with that or not, this is still a once-in-a-millennium opportunity to study some world-class geologic sections - to help us see how our little corner of the world was made.
So, hats off to Bob and the West Texas Geological Society for starting the New Year with a truly remarkable event.
