APRIL LUNCHEON PRESENTATIONS

Featuring the 2011-2012 Awardees of the Robert Anderson Medal for

Outstanding Subsurface Field Studies

“Vermilion 171, Offshore Louisiana”

Cody Louque

UL-Lafayette Dept. of Geology

Abstract

This report discusses structure and stratigraphy of the Vermilion Block 171 Field, as related to entrapment and production of petroleum. Positioned along the Pleistocene-Pliocene trend of offshore Louisiana, the field is located in the east-central portion of the Vermilion Area. The study area is identified by the location map and is centered around the main structure of the field. This structure primarily consists of

northward dipping sand and shale formations, traversed by a series of east-west trending, down-to-the-south faults. Production in the area comes from sands within the Lenticulata 1, Buliminella 1, and Textularia X. These sediments are Pleistocene and Pliocene in age. The structure and production from the following horizons is discussed: the Lenticulata 1 sand, Buliminella 1 sand, and Textularia X sand. Along with the structure maps of the horizons previously mentioned, a structural cross section and five fault plane maps are presented to illustrate the geology of the area.

A brief section of this report discusses field history and development. The sediments of the study area are divided from surface downward into the undifferentiated zone, Lenticulata 1, Buliminella 1, and Textularia X intervals and are discussed in the section on stratigraphy.

Biography

Cody Louque was born in Lafayette, Louisiana, and plans to receive his B.S. degree in Geology from the University of Louisiana at Lafayette this fall. From May to September of 2011, he worked in conjunction with LLOG on the project being presented at the April meeting. Cody is a member of ULGS.


“Florence Field, Vermilion Parish, Louisiana”

Lawrence Ledy

UL-Lafayette Dept. of Geology

Abstract

Florence Field is located in west-central Vermilion Parish in southern Louisiana. The discovery well, Tidewater Florence Club-Arpin #1, was drilled in 1953 by the Tidewater Company, and development of the field was continued by various operators. Cumulative field production to date is 303.7 MBC and 50.13 BCF.

A subsurface study of the field revealed that production comes from three horizons: the Gilmore, Florence, and Trahan sands. These sediments are Early Miocene in age and represent deposition on the continental shelf. Growth faults are common throughout the field and act as the primary source of deformation.

Production can be found in the Gilmore and Trahan sands on the central four-way closure as well as in the adjacent stratigraphic pinch-out of the Florence sand.

Structure maps created by detailed correlation on the Gilmore, Florence, and Trahan sands coupled with fault plane and isopach maps show two possible prospects. Both prospects are located within adjacent fault blocks and are bound by an updip pinchout of one of the mapped sands.

Biography

Lawrence Ledy graduated from Eastern Michigan University with a Bachelor of Science degree in May 2010. He continued his studies in Lafayette where he is currently a graduate student in his last semester.

His thesis research has been under the guidance of Dr. Brian Lock on “The Basin Modeling and Evaluation of Upper Paleocene-Eocene Source Rocks in the North Central Gulf Coast Region.” His work

involves multi-1D modeling of select wells across the north-central Gulf Coast region to evaluate better the thermal maturity of Upper Paleocene-Eocene source rocks in the region. Lawrence has been an active member of the AAPG, SEPM, IAS, and LGS. He consistently appeared on the Dean’s List throughout his

college career and has been awarded local scholarships. He has been a teaching assistant at UL since the fall of 2010 and had previously taught at EMU for two years. During the Fall of 2011 and Spring of 2012, Lawrence was sponsored by Plains Exploration & Production and carried out his thesis research with their support. He has accepted a full-time position with Killam Oil Co. in San Antonio, Texas, beginning in June 2012.

    Cody; Lawrence!

    Congratulations!

    It is a great feeling and accomplishment and certainly the result of very hard work. You sure don’t get there by accident, and everyone knows that. There is hardly a better resume – builder: “You write your own ticket”. ULL winning the AAPG IBA adds tremendous prestige to the Geology program and to you, and other subsurface students as well.

    On May 20, 1981 myself and Mark Despot presented our papers at the LGS. It was a blast. I would like to visit soon and perhaps find someting to do in Lafayette (I have one chapter to finish editing on my dissertation that is otherwise finished). I loved Lafayette and I sure do miss the food! And of course I would like to present my petroleum research work long delayed beyond the imagination, but quite nice.

    If you can, I would like to contact Brian Lock (who was my major professor)- great to see he is active at the LGS. Please say hi to him for me and find his e-mail and also Mansour Rahmatian and Mark Despot if she is still in town. Thanks! And Cody, maybe see you this Fall.

    May you enjoy the best of success,

    Bob Fisher
