Spring PTTC Workshops Tectonic History of the Rocky Mountain Region Thursday, April 4, 2013, 8:30 AM-5:00 PM Colorado School of Mines, Ben Parker Student Center Ballrm A Fee: $250; Includes: refreshments, workbook, and PDH certificate Instructor: Dr. Chuck Kluth, Colorado School of Mines This one day short course will review the tectonic framework and history of the Rocky Mountain region. It will begin with a short review of tectostratigraphic analysis and tectonic maps. The tectonic analysis will begin at the bottom of the geologic column with a brief discussion of the basement underpinnings of the region and Lower Paleozoic cratonic-shelf setting. These shelf deposits are variably preserved in the region but in some areas provide hydrocarbon reservoirs. This cratonic-shelf was interrupted by crustal-scale intraplate deformation in the late Paleozoic, that resulted in widespread development of the Greater Ancestral Rocky Mountains. The uplifts produced arkosic sediments but the voluminous Late Paleozoic sands are from a distal source. The early Mesozoic represents a return to the stable cratonic-shelf that, in late Jurassic, begins to reflect orogeny to the west. The data support the presence of a low-dipping subduction zone along the western plate margin that resulted in crustal shortening and the development of the Cordilleran thrust belt and the basement-cored 'Laramide' Rocky Mountain uplifts and basins. Hydrocarbons, generated by the earliest subsidence related to thrusting began migrating toward the craton, only to be captured by the Laramide structures. Erosion of the uplifts filled the adjoining basins to spillpoints. Later Cenozoic regional uplift or climate changes have resulted in exhumation of the basins. This process is continuing today and was accelerated during the Pleistocene glacial event. How to Find Bypassed Pay in Old Wells Using DST Data Tuesday-Thursday, May 21-23, 2013, 8:30 AM-5:00 PM Colorado School of Mines, Ben Parker Student Center Ballroom C Fee: $650; Includes: refreshments, workbook, and PDH certificate Instructor: Hugh W. Reid Geologists, engineers & technicians who encounter or utilize DST results and reports in their exploration & production decisions. In fact any professional who needs to make more sense of the numerous old DSTs which are present in so many wells, often with confusing results. Particularly appropriate for those prospecting for bypassed pay using logs and geology, who may wish to verify their conclusions from the DST or for regional geologists using show maps of DST results. A key emphasis of the course is to show how to identify missed (damaged) pay in competitor’s ‘dry’ wells & additional pay in your own producing wells. This is an important skill to complement log skills! Objectives By the end of the course participants should be able to accomplish the following: understand DST pressure charts to identify obvious formation damage & depletion (small reservoir) and mechanical problems (eg. tool plugging). recognize high vs. low permeability tests. understand why data from cores and logs often conflict with DST data. “make more sense” of DST results printed in PI well cards and field reports where no chart is available and even estimate approximate permeability & damage in some cases. identify presence of limited natural fractures. appreciate where recoveries of “oil cut mud” and gas rates of “TSTM” may be significant from an exploration standpoint. determine when a gas test is co-producing water. identify gas presence even where no gas was reported in certain tests. identify potential oil zones from DSTs which recovered no oil (from the chart shape and air blow description). estimate the approximate gas rate in DSTs of “GTS TSTM” by knowing the time gas took to reach the surface and the air volume of the test string. make a decision as to whether old DSTs can be recompleted as commercial wells today from limited information.

Geochemistry for Energy Breaking News: COGCC Rule 609 requires Baseline Water Quality Monitoring. RMAG Foundation Sponsors the Excellence in Teaching of Earth Science Award In 2000, the RMAG Foundation instituted an award to honor elementary or secondary school teachers who have promoted teaching of earth science to K-12 students. The winner receives a commemorative plaque and a $1000 cash award provided by the RMAG Foundation, and is recommended as the RMAG’s candidate to compete for the AAPG Rocky Mountain Section, Teacher of the Year award. This award honors the best earth science teacher in the Front Range area from either an elementary or secondary school. If you are a teacher or know of a teacher who could be a candidate please contact the K-12 Public Outreach Committee through the RMAG office at 910 16th Street, Suite 1125, Denver, CO 80202, by telephone at 303-573-8621, or email at staff@rmag.org to receive an application form. The application deadline this year is Friday May 3, with the winner to be announced on or before May 11. » stable isotope analysis of dissolved hydrocarbons in water samples.
