The AGL’s mission is to create and apply new geophysical means of imaging and understanding the subsurface. We are particularly dedicated to conscientious resource discovery and recovery. Faculty members work with the energy industry, professional societies, and other institutions to develop advanced technologies and help in educating the next generation of geoscientists. We use scaled laboratory measurements, field surveys, numerical modeling, and digital processing to develop novel methods of subsurface analysis.

The CBTH Project seeks to create a GIS-based digital and atlas synthesis of available seismic and well data to define the regional hydrocarbon potential of a vast region affected by the Mesozoic breakup of Pangea.
This project, which has been operating since September 1, 2005, includes:
- Known hydrocarbon basins of onshore and the lesser known offshore basins of the Caribbean and northern South America (Venezuela, Colombia, Trinidad, Suriname, Guyana, Northern Brazil)
- The U.S. and Mexico sectors of the Gulf of Mexico, and
- The rifted-passive margins of the Central in eastern North America and western Europe, and the
- South Atlantic in South America and west Africa.
Our main objectives are to compile all the available digital seismic and published data in a GIS database to provide an integrated geologic synthesis of tectonosequences, depositional systems, major structures, petroleum geology, paleogeographic maps, and quantitative plate reconstructions for a better understanding of the hydrocarbon systems in the region. Our largest concentration of data and current studies are in the Caribbean and the U.S. and Mexican Gulf of Mexico, but we have several recently completed and ongoing projects in Brazil and west and northwest Africa.

The Paleomagnetism Research Laboratory (PRL) at UH contains an Agico JR-6A spinner magnetometer, which can measure samples with a wide range of magnetizations (10-6 to 104 A/m). It is housed in a mu-metal shielded room with ambient magnetic fields of <200 nT.
The PRL contains equipment for sample demagnetization by both thermal and alternating field techniques. The thermal demagnetization unit is an ASC model TD-48SC, which is suitable for heating batches of samples between room temperature and 800 C. It has a cooling chamber with a low ambient magnetic field (<1 nT) to prevent the acquisition of spurious magnetizations. The alternating field magnetization unit is a D-Tech model D-2000AF, which generates unidirectional demagnetizing fields between 0 and 200 mT for demagnetization and the study of coercivity spectra of the remnant magnetization of materials. The demagnetization instruments are housed in a second shielded room, constructed of 3 layers of transformer steel, which also has internal ambient magnetic fields of <200 nT.
The lab also contains an Agico-Kappabridge model KLY5-A magnetic susceptibility meter, which can measure in phase and out-of-phase magnetic susceptibility and anisotropy of magnetic susceptibility of rock samples.
Please contact Dr. William Sager for more information about the PRL.
