ABSTRACT: Authigenic quartz cement is the most common pore-occluding mineral in deeply buried (>2500 m) quartzose sandstones. Conventional cementation models often fail to predict the occurrence of deeply buried porosity confirming that our understanding of quartz diagen-esis is still limited. We have utilized advanced analytical capabilities to improve our understanding of controls on quartz development in several examples where porosity is preserved in deep, hot sandstone reservoirs
In this study, several advanced analytical techniques were used to evalu-ate the crystallographic and compositional controls on the formation of microcrystalline quartz. SEM/Cathodoluminescence (CL) confirms that quartz overgrowths have a complex growth history. Previous workers

Marsha French is an Ad-junct Professor in Geolo-gy at the Colorado School of Mines. She retired in October, 2012 after 34 years at ExxonMobil where she was a Senior Research Associate at ExxonMobil’s Upstream Research Lab in Houston. She holds a Bachelor’s Degree and Master’s De-gree in Geology and Geo-
chemistry from the University of Wyoming and a PhD in Geology from the University of Liverpool in England.
Marsha began her career 34 years ago at Mo-bil Oil Co. in their Minerals Division in Denver where she worked in coal, uranium, and lead/zinc exploration. In 1982, she moved to Mo-bil’s Oil and Gas Division in Dallas and worked a variety of assignments in onshore and off-shore exploration and production. In 1987, she began supervising teams exploring in the onshore U.S., as well as, Kazakhstan, and Azerbaijan. Following those assignments she
worked in Mobil’s Headquarters in E&P Plan-ning and in 1997, she moved to Norway as the Manager of Planning and Performance Analysis. In 2000, she returned to the U.S. and held a variety of leadership positions in Exploration and in 2005, she returned to her technical roots in ExxonMobil’s Upstream Re-search Company to work on her passion, res-ervoir quality in sandstone reservoirs. Her current research is focused on predicting po-rosity preserving microcrystalline quartz in high temperature reservoirs. She joined the Colorado School of Mines as an Adjunct Pro-fessor in November, 2012 and currently teaches in the Geology Department.
She and her husband, Art, who also retired from ExxonMobil as a geologist after 33 years, have two daughters, Katie, who is a screen-writer and producer in Los Angeles and Julia, who is General Manager of The Donor Solution and has a concierge business Concierge if You Please in Houston. They also have two Labra-dor retrievers, Ruby and Gypsum and enjoy hiking and fly-fishing in Colorado.
SPEAKER’S BIOGRAPHY: DR. MARSHA W. FRENCH
Colorado School of Mines
(Kraishan et al. 2000) suggested that CL pat-terns in quartz cement are largely due to trace elements rather than defects and that alumi-num varies consistently between each cement phase. Electron Backscatter Diffraction (EBSD) combined with Wavelength Dispersive Spectrometry (WDS) confirms that the com-plex banding visible in CL is not due to chang-es in crystallographic orientation but more likely variations in quartz composition associ-ated with changes in pore fluid composition and/or reservoir conditions. Secondary Ion Mass Spectrometry (SIMS) analysis provides maps of ultra-trace element distribution that confirm that trace amounts of aluminum, iron,
and titanium can be used as proxies for defect density and temperature. Additionally, SIMS analysis provides oxygen isotope data provid-ing insight into the initial reservoir conditions and temperature of formation of microcrystal-line quartz in several formations.
Integrating the results from these advanced analytical techniques has helped us develop our understanding of the processes controlling the formation of quartz cement and improved our ability to reconstruct the reservoir diage-netic history and/or trace element impact on quartz growth leading to a proposed model for predicting porosity preservation in deep, hot sandstone reservoirs

UPCOMING FCGS MEETINGS
The leaves are starting to turn and a new season of talks is right around the corner! Our new President-Elect Laurie Van Ingen, whom some of you may have met at this year’s picnic, has already filled this year’s ticket with great speakers. Laurie has been a long-distance FCGS member for many years. He and his wife (also named Laurie!) recently became full-time residents after retiring and moving from Dallas. Laurie spent over 38 years in the Oil and Gas industry and is bringing a lot of knowledge and energy to the Society.
The Tocito, El Vado and Gallup Sands Field Trip led by Lesli Wood in June was well attended and generat-ed a lot of interest in making a field trip happen again-possibly next summer in conjunction with the New Mexico Geological Society.
We had fantastic weather for the picnic this year and, thanks to Tim Rynott and Brook Herb, had the op-portunity to mingle with the Durango Petroleum Club members as well. Fun was had!
Our first talk will take place on October 4th in Durango; Dr. Marsha French will be talking about the evils of quartz cement. Be sure and RSVP to Laurie so that we have an accurate head count for the caterers.
Thanks and see you there! Rebecca

Abstract: In the past few years, mud gas mass spectrometry has gained popularity as an on-site, re-al-time mud gas analysis tool replacing conventional equipment. The tool, known as the DQ1000 from Flu-id Inclusion Technology is now offered by numerous logging companies and is said to identify pay, wet-ness, reservoir compartmentalization, and fluid con-tacts to name a few.
We ran several pilot studies in the Wind River Basin in Wyoming and the Piceance Basin of Colorado to evaluate specific questions surrounding our production from the fluvial sections of the Fort Union and Wil-liams Fork respectively.
A primary issue associated with gas wells at Frenchie Draw in the Wind River Basin, WY is water produc-tion. The vertical wells studied targeted the Lower Fort Union sands below the Tertiary Waltman Shale
member, and the Lower Fort Union (LFU) sand inter-vals between and below the “A” and “C” coal seams. Because of its ability to quantify trace hydrocarbon species with a much stronger affinity to water, mud gas mass spectrometry was employed to help under-stand the hydrological plumbing system. However, in addition to providing hydrological clues, the mass spec data also yielded insights into the sources of the gas, gas migration and thermal maturity, and the location of specific seals and compartments.
In the Piceance, questions surround the variability seen in production from wells with 10-20 acre spac-ing; questions we hoped the mass spec would help us to answer. Similar to Frenchie, the mass spec data provided insight into gas migration and thermal ma-turity, but the data were just as variable as gas and water production from the wells.
