Dr. Faisal Abuhmida.jpg

We are delighted to announce that Faisal Abuhmida has joined our paleo team!


Dr. Faisal Abuhmida is a professional geologist (petroleum geoscientist) with over 30 years of experience. He is an expert in the palynology of the lower Paleozoic (Acritarch, Chitinozoan, and Spores), upper Paleozoic spores, and Mesozoic ages. 

  • His experience includes age dating, correlation, paleoenvironment, and palynofacies analysis by using kerogen type, paleoclimate, and organic thermal maturity, integration of biostratigraphic age and paleoenvironment (palynology and palynofacies) with other geological data (wireline log, sedimentology, and geochemistry data) at both a regional and a reservoir scale. 

  • He has developed the Paleozoic zonal scheme for all the sedimentary basins in Libya, including the detailed Triassic and pre-upper Cretaceous palynology and sedimentology of the southeast Sirte Basin.

EGS_Vann Smith.jpg

We are delighted to announce that Vann Smith has joined our paleo team!


Dr. Vann Smith has a PhD degree in palynology from Louisiana State University. His dissertation research focused on the Paleocene-Eocene palynology of drill cores from the Chicxulub impact crater in Yucatán, Mexico (IODP Expedition 364). Dr. Smith completed a detailed taxonomic work of pollen and spore taxa, including descriptions of new species, for the project. After graduation, he worked as a college instructor and postdoctoral researcher. His postdoctoral research and collaborations included the analysis of Holocene palynological samples from lake sediments in the southeastern United States and Wilcox Group samples from the deepwater Gulf of Mexico. Over the years, multiple papers were published from his work. He received special training from mentors who helped develop the palynological scheme for the Wilcox. In addition to palynology, Vann also worked as a staff nannofossil specialist with offshore drilling experience.

His expertise and skills include:

  • Palynological analysis (palynomorph taxonomy, Paleocene-Eocene/Holocene)

  • Integration of multidisciplinary biostratigraphic, lithologic, wireline log, and other paleoenvironmental datasets 

  • Nannofossil work experience on offshore drilling rigs

  • Knowledge of statistics including morphometric and quantitative biostratigraphic techniques

  • Experience with teaching, lecturing, and instruction

Wishing you a Happy Thanksgiving!

"May your stuffing be tasty.
May your turkey be plump.
May your potatoes and gravy have nary a lump.
May your yams be delicious, and your pies take the prize,
and may your Thanksgiving dinner be filled with happiness!"

Rapid Rock Results
Example from Permian Basin

The Rapid Rock Results (RRR) services allow low cost and fast turnaround organic & inorganic screening on rock samples. Our goal is to help make more informed drilling and completions decisions through the utilization of fast, efficient, and integrated Rapid Rock Results data.

RRR Analytical Techniques:

  • LECO TOC (Total Organic Carbon) - Organic Richness

  • HAWK Pyrolysis - Classic Pyrolysis; HAWK PAM; Customized Pyrolysis

  • XRD (X-Ray Diffraction) - XRD Bulk & Clay; Mineralogy; Shale Brittleness 

  • XRF (X-Ray Fluorescence) - Major & Trace Elements


RRR Example from Permian Basin:

The video above shows an example of RRR geochemical logs from Permian Basin. If you are interested, please feel free to contact us and our experts have more insights for you.
