|UPPER PALEOZOIC MOUNDS OF THE SACRAMENTO MOUNTAINS, NEW MEXICO
APPLICATIONS TO SUBSURFACE RESERVOIRS
DATE: March 13-18, 2009
WHERE: Alamogordo area, southeastern New Mexico
LEADERS: Jeffrey J. Dravis (Dravis Interests, Inc., Houston, Texas)
Harold R. Wanless (University of Miami, Florida)
FOR: Geologists, Geophysicists, Reservoir Engineers, Log Analysts
and Managers. Space is limited.
COST: $2550 USD
GOAL: This seminar will introduce you to classical exposures of Mississippian, Pennsylvanian and Permian mounds and related facies that outcrop in the Sacramento Mountains of southeastern New Mexico. These outcrops provide you with a sense of scale and geometry, which is extremely important when relating seismic and well log data to these types of exploration plays, or their reservoir development. We apply principles of comparative sedimentology to these Paleozoic facies and sequences, and discuss where the modern relationships help us, and where they do not. We will tie field observations and relationships to subsurface analog plays and reservoirs.
Currently, our understanding of Paleozoic carbonate mounds is in a time of significant controversy. Geoscientists are in disagreement as to whether:
• mounds are formed in place or are largely transported slump features;
• mounds are deep or shallow;
• mounds form in a portion of a ramp related to nutrients or are positioned in response to tectonic flexural hinges;
• their nutrient source was from its shallow water setting, from upwelling of deep basin waters, or from seeps from the substrate below;
• their source of marine cements was from its shallow water setting, from upwelling of deep basin waters, or from seeps from the substrate below; and
• their carbonate mud was detrital or precipitated by microbes.
Similarly, there is controversy as to the diagenetic histories of these mounds, the cause and timing of cementation phases, and the controls on porosity evolution.
Throughout this seminar we will use the sedimentological features observed within the mounds, associated facies relationships, regional and local setting, and petrological evidence to sort through these conflicting interpretations. We will contrast our observations with subsurface productive mound reservoirs of comparable age.
Jeffrey J. Dravis: Consulting petroleum geologist with 30 years of experience and Adjunct Professor of Geology, Rice University; 8 years with Exxon Production Research and chairman of Exxon's Advanced Carbonate School. Since 1987, he has taught 160 basic and advanced carbonate seminars. Past consulting projects (>115 in number) include reservoir studies of mounds and buildups in Texas (Paleozoic & Mesozoic), Devonian and Mississippian of W. Canada, Permian of west Texas and Thailand, and Pennsylvanian of Four Corners region.
Harold R. Wanless: Professor of Geology and Geophysics, and chairman, University of Miami; consultant and field trip leader for Exxon, Tenneco, Occidental, and Chesapeake. Has conducted worldwide research on modern and ancient carbonates since 1966. He is an active researcher on modern carbonate mounds and upper Paleozoic mounds in New Mexico.
Meet in El Paso, Texas before 2 PM.
Drive to Cloudcroft, New Mexico; evening Orientation: 6:30 – 7:30 PM
Smaller Mississippian Mounds exposed in Marble and
Alamo/Deadman’s Canyons (crinoidal and bryozoan buildups).
Larger Mississippian Muleshoe Mound (hike to base of mound, examine various core, flank and slump facies; hike to crest of mound to examine seaward crest facies. Discuss the paleoenvironmental setting and mound diagenesis. Visit flank and inter-mound facies on return hike).
Pennsylvanian Mud Mounds (phylloid algae) exposed in Dry Canyon.
Dry Canyon Highway Road Cut – evaluation of Pennsylvanian reciprocal carbonate and siliciclastic sedimentation.
White Sands National Monument: Playa Evaporite Model.
Permian Scorpion Mound (vertical and lateral zonation of phylloid algal core facies and character of flank and inter-mound facies. Examine and discuss early and late diagenetic processes and fabrics).
Group Discussion: Summary of field trip and discussion of the play potential of Upper Paleozoic carbonate mounds and reservoir case studies.
Depart 8:30 AM for El Paso, Texas (2-3 Hour Drive).
Fly out to home cities.
LOGISTICS – Please Read Carefully
You should plan to arrive in El Paso, Texas no later than 2 PM on March 13, 2009. Departure is from the same airport on March 18, 2009.
Delegates must be physically fit and in good health.
The total fee for the seminar is $2,550.00 (U.S).
This fee includes:
*Transportation to and from Cloudcroft, and in the field, by bus.
*Lunches, snacks and drinks in the field (Delegates are responsible for their breakfasts and dinners, as well as personal bar tabs, however).
*Field guidebook with color diagrams, and a CD handout.
Each participant is responsible for booking his or her flights to and from El Paso, Texas. Each person is responsible for payment of their hotel room and associated room charges. We will be staying at The Lodge in Cloudcroft, New Mexico (Elevation 9000 feet). We will book the room for you at The Lodge but you must guarantee it with a credit card. We have blocked out rooms with king beds for $99 USD per night ($110.88 with tax). These discounted room rates expire February 15th.
SAFETY ON THE TRIP (PLEASE READ CAREFULLY):
The goal of this trip is to return safely without mishap to anyone. In everything you do, think whether your actions might unnecessarily endanger yourself or someone else. We will never force you to go somewhere where you are not comfortable.
There will be easy to moderate hiking on most days on this seminar. The hike up Muleshoe Mound, however, is more strenuous. It is imperative that you be in good shape prior to participating on this seminar.
Be cautious. We will be hiking in rocky and sometimes steep terrain. Take your time. Always watch where you are walking. Cactus, spiny yucca-like plants, and unstable rocks can make your day uncomfortable. Snakes should be hibernating at this time. Long pants, long shirts, and boots protect you from the sun and from scratches, cactus stabs, and rocks. If you get a blister, stop and fix it. You will need your feet the entire trip.
In March, it may be warm and dry, or cold and wet. Make sure you drink plenty of fluids throughout the day and evening. Bring rain protection and a fleece or coat to keep warm in case the weather turns wet or cold. Wear sun protection. Excessive sun will tire you.
After you register, we will send you a list of suggested gear and clothing to bring on this trip.
A full refund, less the nonrefundable registration fee ($300), will be given if written cancellation is received by February 15, 2009. No refunds after February 15, 2009. Substitutions are allowed.
LATE REGISTRATION after February 15, 2009 will incur an additional $300 fee, assuming space is available.
Passport for U.S./Canadian/British citizens; visas for others. It is your responsibility to determine if you need a visa. Check with a nearby consulate or embassy. Double check with your travel agent (they have made mistakes in the past for some participants).
NOTE: We will pass though a U.S. Immigration station between El Paso and Alamogordo, New Mexico. You must have your passport available (and visa, if appropriate) when we are stopped and checked.
