Alaska's Oil & Gas Consulting Company

Robert B. Blodgett PH.D. – Geologist

Robert Blodgett has over 37 years of significant experience in Alaskan geology. His fundamental knowledge and expertise is in stratigraphy and paleontology and he has worked in nearly all major on-shore petroleum basins in the state (North Slope, Interior Basins (Kandik, Minchumina, and Holitna basins), as well as Cook Inlet and the Alaska Peninsula. His work involves numerous consulting projects for the petroleum industry and his clients have included: Shell Oil, BP, ARCO Alaska, ConocoPhillips, Apache Corporation, Sohio Petroleum Company, Union Oil Company, Hewitt Mineral Corporation, U.S. Department of Energy, and Louisiana Land and Exploration Company. His consulting work allowed him to spend several years of concentrated study on Mesozoic cores from the North Slope and southern Alaska (Cook Inlet and the Alaska Peninsula) deposited in the Alaska Geologic Material Center in Anchorage and the United States Geological Survey (USGS) Denver Core Facility. He was formerly one of two stratigraphic paleontologists assigned to Alaskan studies by the former Branch of Paleontology & Stratigraphy of the USGS.


 Ph.D Geology, Oregon State University, Corvallis, 1987

M.S. Geology, University of Alaska, Fairbanks, 1978

B.S. Geology, University of Alaska, Fairbanks, 1975



Conducted work in nearly all the major on-shore sedimentary basins in the state, including the interior basins, the North Slope, south-central Alaska (Cook Inlet), southeast Alaska and the Alaska Peninsula. Project work involved measuring of stratigraphic sections, geochemical sampling, field mapping, paleontological sampling and basin analysis and mapping of the surface and subsurface. Other North Slope related activities involved a study of the sequence stratigraphy of the Shublik, Sag River Sandstone and Otuk formations. Provided advice for leasing tracts and calculating potential reserves for petroleum exploration in the Alaska Peninsula and the Cook Inlet Basin. Interpreted geologic information from subsurface cores, microscopic thin sections, made fossil identifications of both megafossils and Foraminifera, and selected samples for identification of petroleum source rocks. Presented a number of talks on the petroleum potential of Cook Inlet and the Alaska Peninsula to professional audiences as well as at requested presentations for the oil industry and Alaskan Native Corporations. Constructed an online paleontological website ( on Alaska paleontological data (the only such site devoted to a single state). Major clients during this interval included Shell Oil, BP, Apache Corporation, ConocoPhillips, Hewitt Mineral Corporation, U.S. Department of Energy, Alaska Division of Geological & Geophysical Surveys (ADGGS), USGS, U.S. National Park Service, and Yukon Geological Survey.



Undertook research on the paleontology and stratigraphy of rock strata present in the Alaska, Western Cordillera of the U.S., and Mexico. Published these results in both internal USGS and external peer-reviewed journals. Nearly all of my field studies were focused on the western U.S., especially Alaska. Acquired broad experience with the USGS fossil collections ranging from Paleozoic to Mesozoic in age. Extensive field work conducted in various parts of Alaska, including Arctic Alaska resulting in further age and stratigraphic refinement of strata in the Arctic National Wildlife Refuge (ANWR).


Spent several summers as a consultant to Sohio Petroleum Company, Union Oil Company, Louisiana Land & Exploration Company, and ARCO Alaska, leading them in the field in various interior basins (esp.Minchumina and Holitna Basins, as well as the Kandik Basin) to conduct stratigraphic reconnaissance and basin analysis study of the Paleozoic sections exposed along their margins. Measured numerous stratigraphic sections and collected samples for both source rock analysis and porosity and permeability study. Established biostratigraphic frameworks for these basins which had up to then been largely unknown. Extensive field work conducted in ANWR with the ADGGS between 1985-1989, resulting in a stratigraphic revision and formal naming of new stratigraphic units in the pre-Mississippian. Work done with numerous field parties of the ADGGS throughout the state. Also worked with a number of mining companies in interior Alaska.


 Approximately 200 publications and 150 abstracts, mostly concentrated on stratigraphy, paleontology, geologic mapping, tectonics, and petroleum potential of Alaska and the U.S. Western Cordillera (list of publications available or request).  Editor of several large monographs.  Also wrote numerous proprietary industry reports to various oil companies and Alaskan Native Corporations on the petroleum potential of selected areas in northern and southern Alaska.
