Theory and Perspective on Stimulation of Unconventional Tight

However, compared with North American, all the tight oil reservoirs discovered in China has its own characteristics including continental sedimentation, interbeded formation, worse reservoir physical properties and less oil reserves per unit volume, which make it much harder to stimulate. Based on thorough analysis of successful stimulation experiences in North American, taking the characteristic of China’s tight oil reservoir into consideration, this article emphasized that increasing stimulated volume must be paid attention to, what’s more, integrated fracturing technology must be adopted into tight oil reservoir stimulation to promote both production and recovery efficiency. -

Diagenesis in the Upper Cretaceous Eagle Ford Shale

Golden, Colorado Date ______________________ Signed: ____________________________________ Allison Schaiberger Signed: ____________________________________ Dr. Steve Sonnenberg Thesis Advisor Signed: ____________________________________ Dr. Stephen Enders Interim Department Head Department of Geology and Geological Engineering Golden, Colorado Date ______________________ ii ABSTRACT This study utilizes three cores provided by Devon Energy from LaVaca and Dewitt Counties, TX, which were analyzed with a focus on diagenetic fabrics within the Lower Eagle Ford. A better understanding of paragenesis within the organic-rich Lower Eagle Ford was developed with the use of XRF and XRD measurements, thin section samples, stable isotope analysis, and CL analysis. The majority of diagenetic alteration occurred early at shallow depths within anoxic/suboxic environments and slightly sulfate-reducing conditions from diagenetic fluids with varying isotopic composition. Diagenetic expression variation is most influenced by the depositional facies in which alteration occurs. Within the study area, four identified depositional facies (A-D), and five diagenetic facies (1-5) were identified within the Lower Eagle Ford study area based -

Digital Outcrop Models of the Eagle Ford Group in Lozier
DIGITAL OUTCROP MODELS OF THE EAGLE FORD GROUP IN LOZIER CANYON, TERRELL COUNTY, TEXAS A Thesis by DREW EDWARD DAVIS Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Juan Carlos Laya Committee Members, Michael Pope Walter Ayers Head of Department, Michael Pope May 2017 Major Subject: Geology Copyright 2017 Drew Davis ABSTRACT The Eagle Ford group was a prolific producer of unconventional oil and gas in south Texas during the last decade. Operators typically target the Lower Eagle Ford formation to drill horizontal wells with lateral lengths averaging nearly 1 mi (1.61 km). Geologic variability can be significant at these distances, thus an understanding of lateral variability of reservoir thicknesses, facies distributions, and fractures paired with geochemical and petrophysical data is valuable in characterizing unconventional reservoirs. High-resolution digital outcrop models (DOMs) using photogrammetry techniques provide a unique tool to study variability of Eagle Ford group strata in outcrops in Lozier Canyon in Terrell County, West Texas. Stratigraphic variability within the Eagle Ford group is well documented; however, lateral variability of Eagle Ford strata is minimally understood and is fundamental to developing this productive unconventional play. This project focuses on world-class outcrops that expose complete vertical sections of the Eagle Ford group. The study area covers a north-to-south straight line distance of 6.2 mi (10 km) allowing analysis at reservoir-scale. The average gross stratigraphic thickness of the Eagle Ford group increases by approximately 27.8 ft (8.47 m), a 13.59% increase, from the Scott Ranch site in north Lozier Canyon to south Lozier Canyon. -

Mesozoic of the Gulf Rim and Beyond: New Progress in Science and Exploration of the Gulf of Mexico Basin 35th Annual Gulf Coast Section SEPM Foundation Perkins-Rosen Research Conference 2016 Program and Abstracts Marathon Conference Center Houston, Texas December 8–9, 2016 Edited by Christopher M. Lowery John W. Snedden Norman C. Rosen Mesozoic of the Gulf Rim and Beyond: New Progress in Science and Exploration of the Gulf of Mexico Basin i Copyright © 2016 by the Gulf Coast Section SEPM Foundation www.gcssepm.org Published December 2016 The cost of this conference has been subsidized by generous grants from Hess Corporation and Freeport McMoRan. ii Program and Abstracts Foreword Thirty-two years ago, the Gulf Coast Section of SEPM convened its 3rd Annual Research Conference on the Jurassic of the Gulf Rim (Ventress et al., 1984). At that time, the Mesozoic was being explored onshore as conventional carbonate and sandstone reservoirs, the Cantarell Field (Mexico) was in its early stages of production, and offshore areas of the U.S. Gulf of Mexico were primarily Cenozoic reservoir targets. Today, the Mesozoic is known to contain large discovered volumes in unconventional shale reservoirs onshore, Cantarell is in decline, and Mesozoic discoveries are being made in the ultradeep water of the Desoto and Mississippi canyons. Mexico has opened for international exploration, and political events in Cuba may eventually cause it to follow suit. This increased economic interest in the Mesozoic of the Gulf of Mexico has in turn spurred a huge volume of scientific research and increased investment in research and access to samples from wells in previously undrillable regions. -
The Lower Woodbine Organic Shale of Burleson and Brazos Counties, Texas: Anatomy of a New “Old” Play
The Lower Woodbine Organic Shale of Burleson and Brazos Counties, Texas: Anatomy of a New “Old” Play Richard L. Adams1, John P. Carr1, and John A. Ward2 1Carr Resources, Inc., 305 S. Broadway Ave., Ste. 900, Tyler, Texas 75702 2PetroEdge Energy III, 2925 Briarpark Dr., Ste. 150, Houston, Texas 77042 ABSTRACT The Lower Woodbine Organic Shale, in the southwest portion of the East Texas Basin, is a very organic-rich shale with high resistivity, a hot gamma ray response, and very good mud log shows. This zone owes its high organic content and the resultant well-established oil pro- duction to its deposition in a silled basin, the product of a prograding delta from the north and northeast, a shelf-rimming Sligo/Edwards barrier reef complex to the south and southeast, a large basement high that affected water depth to the east, and a con- stricted area between the Sligo-Edwards Shelf Margin and the San Marcos Arch to the west. Within this silled basin, the zone grades from producing 30–35 gravity oil in northern Brazos County to dry gas in southernmost Grimes County. In 2008, concurrent with the development of the “Eagleford play” in South Texas, Apache began a program recompleting wells from the underlying Buda and the overly- ing Austin Chalk into the Giddings (“Eagleford”) zone. The early recompletions were vertical completions with very small cumulative oil production. Later, they would drill several short lateral horizontal wells to better test this organic shale. The data from the Apache wells would prove to be invaluable in the current round of evaluation and drilling that began in 2012.
