The Applied Geodynamics Laboratory (AGL) was established in mid-1988 by Martin Jackson. Since 1980, he had focused on salt-tectonics research in the Gulf of Mexico and Iran, after a previous research and teaching career in structural and metamorphic geology of high-grade metamorphic and igneous Precambrian terranes in Africa.

The AGL was designed to fill a noteworthy gap. In 1988, there were no full-scale tectonic modeling laboratories in U.S. academia although several existed elsewhere and in industry.

Presentations to and discussions with many oil companies in early 1988 by Martin and Marcus Milling (then BEG Associate Director) convinced us that the oil industry would support a tectonic modeling laboratory specializing in salt tectonics. The AGL was therefore established as a consortium of Industrial Associates. Membership was on an annual basis, but the goal was a long-term research project staffed by fulltime professionals.

The AGL and the Reservoir Characterization Research Laboratory were the first large-scale, IA-supported consortia at the BEG. The BEG Director, William Fisher, obtained seed money of about $100,000 from The University of Texas at Austin to equip the laboratory. The largest single purchase was a high-speed, high-capacity centrifuge. This was selected on the basis of Martin's experience modeling as a Visiting Scientist at Uppsala University in 1984 and from considerable advice and assistance from Professors Talbot and Dixon.

The first researcher recruited for AGL was Bruno Vendeville. He joined in early 1989 after completing a post-doctoral appointment at Texas A&M University, during which he had built a basic deformation rig at their Center for Tectonophysics. Bruno was highly experienced in all types of extensional tectonics and the technique of sand-and-silicone modeling from his Ph.D. research at Rennes University. For salt tectonics, sand-and-silicone was a superior technique to the more-sophisticated centrifuge approach. This method has been continually refined and has provided the core of AGL's modeling program ever since. Bruno left in 2003 to take up a tenured position at the University of Lille, France.

A few months later in 1989, Dan Schultz-Ela was recruited for mathematical modeling, based on his strain-analysis expertise gained from a PhD at the University of Minnesota. Dan's early work at AGL focused on analytical forward modeling and software development of Restore (structural restoration) and GridStrain (strain analysis). Later, he focused on 2-D finite-element modeling, and, more recently, 3-D finite-element modeling.

In 1993, Giovanni Guglielmo was recruited for his skills in 3-D visualization and multimedia publications. Giovanni had completed a post-doctoral appointment at The University of California at Santa Barbara focusing on strain analysis in batholiths. Within a short while, Giovanni pioneered the AGL website, made our first animations of models and restorations, and produced 3-D visualizations of physical models. He left in 1997.

Michael Hudec joined the research team in 2000 after part-time research contributions the previous year while on the faculty of Baylor University. His skills in petroleum exploration, structural restoration, 3-D model building and visualization, and workstation seismic interpretation were developed at Exxon Research Production and a PhD at The University of Wyoming. He was promoted to Co-Principal Investigator in 2002 to share leadership of AGL with Martin.

Tim Dooley arrived at AGL in November 2003, to take over from Bruno Vendeville, from a position as Senior Researcher/Laboratory Manager for the Fault Dynamics Research Group, Royal Holloway University, London. Tim has more than 15 years experience in modeling strike-slip and extensional faulting, shale tectonics, salt tectonics, and inversion. He brought with him a record of innovative modeling techniques and striking graphics displays. Since arriving Tim has modernised the laboratories, equipping them with digital cameras, a surface laser scanner, 3 new deformation rigs and various other technical enhancements.

Jozina (Josie) Dirkzwager joined the research team in May 2006, to fill the numerical modeling gap left by Dan Schultz-Ela when he departed for a teacher's life in Colorado. Originally trained as a structural geologist, she spent 4 years at the Geophysical Institute of Karlsruhe University, Germany cross-training to a numerical modeler. Her research focuses on advanced subsurface modeling by integrating structural geology, theoretical and practical geomechanics, and numerical modeling. Her initial research focused on modeling the advance of salt sheets. Currently she's working on multilayered salt modeling and 3D finite element modeling.

Several Master's and PhD students, mostly from The University of Texas at Austin, have spent months or years doing modeling at AGL for their graduate research. In order of arrival, these included Sean Boerner, Shing-Tzong Lin, Hongxing Ge, Mary Johns, Brent Couzens (Texas A&M), Patrick Walsh, Joel Le Calvez, Ryan Mann, Asif Muzaffar, Laurent Boniface (Université de Perpignan, France), Christine Fox, and Lies Loncke (Géosciences Azur, France), and Vernon Moore (Texas A&M).

In addition, AGL has been fortunate to host several Visiting Scientists, almost all of who provided their own funding to work with us: John Sclater (The University of Texas), Hemin Koyi (Uppsala University, Sweden), Ruud Weijermars (Uppsala University, Sweden), Jean-Pierre Bobineau (EuroSim, France), Olivier Merle (Université de Rennes, France), Peter Cobbold (Université de Rennes, France), Elisabetta Costa (Universita di Parma, Italy), and Virginie Gaullier (Université de Perpignan, France).

The AGL grew at a time when concepts of salt tectonics were changing rapidly and radically. In the early 1980s, only a handful of researchers published a few papers that advanced understanding of salt tectonics-rather than merely used existing concepts. The most seminal of these contributions was a series of papers on an Iranian salt glacier by Christopher Talbot and coworkers at the University of Dundee (Scotland). By the late 1980s, the study of salt tectonics exploded. Huge amounts of seismic data from salt basins were being scrutinized for hydrocarbon exploration, and the first truly realistic salt-tectonic models were being generated by Bruno and colleagues at Rennes University, to be followed by those from AGL. This revolution completely rebuilt the conceptual framework of salt tectonics and widened the field of view from the narrow periphery of salt domes into the role of salt on entire continental margins. Research at AGL contributed greatly to this revolution in understanding, either solo, in collaboration with industry research groups, or merely in parallel with such groups.

For its first 10 years, the AGL concentrated on tectonic modeling. In 1998, while continuing the modeling program at full strength, we introduced an equally large program of seismic-based geological studies in scientifically rewarding basins. The goal was to apply the new concepts gained by modeling to test and refine these concepts on natural basins and to use these geologic studies to guide further modeling. We selected the deepwater central Kwanza Basin of Angola. Research by Martin and Mike was expanded onshore to include a geotraverse across the entire 360-km-wide salt basin. In 2001, we began research on the Lower Congo Basin in deepwater southern Gabon. In 2003, we plan to apply the approaches and concepts from the West African studies to the deep-water Gulf of Mexico.
