Research

Without research, biostratigraphy would stagnate. Although we work in a confidential industry we are fortunate that occasionally our clients grant us permission to publish articles on their material. Often we source samples ourselves (especially field samples) because of personal interest, analyse them and publish the results.

RESEARCH ASSOCIATE
 
Dr Mike Simmons is Technology Fellow for Geosciences and the Energy Transition for Halliburton Inc. He is a global thought-leader on industry-related geoscience topics such as sequence stratigraphy, sea-levels; their magnitudes and timing, basin analysis, large-scale and dimensionless geoscience databases, predictions using AI & ML and, not least, the Energy Transition. Formerly 17 years with BP and subsequently at Aberdeen University and chief geoscientist at CASP, Mike was a co-founder and Director of Neftex Geological Consultants Ltd. in 2001.

Mike is also a trained biostratigrapher and is a key colaborating partner on many aspects of GSS Geoscience's research. Mike is senior- and co-author of many papers listed below, for example.

Mike Simmons and Mike Bidgood are currently focussing on the biostratigraphic aspects of the Mid Cretaceous, in particular the Cenomanian (where they have recently published reviews on the planktonic and the "larger benthic" foraminiferal biostratigraphy), and the Turonian and Coniacian stages. They are also involved in ongoing research centering on the Cenozoic evolution of the Thrace Basin and Western Black Sea Basin of Paratethys.
 

In Preparation/Press:

Simmons, M.D. & Bidgood, M.D. Cenomanian larger benthic foraminifera - a stratigraphic review. [an assessment of the validity of published data to evaluate the identity and stratigraphy of LBF recorded from Cenomanian strata - an extension paper to our 2023 review of "planispiral" forms, this data includes the assessment of over 100 species and which will be published as a series of papers covering separate taxonomic groups]

Simmons, M.D. & Bidgood, M.D. Cenomanian marine biostratigraphy: a review. [a review, comparison and integration of the stratigraphy of numerous fossil groups e.g., ammonites, inoceramids, foraminifera, nannofossils, palynomorphs, bivalves, ostracods, microcrinoids, radiolaria, together with radiometric dating, isotope curves and sea-levels]
