About Us

Worldwide Geochemistry offers expertise in petroleum systems analysis for evaluation of both conventional and unconventional resource systems. Our consulting services include specific assessment of the likelihood of petroleum charge in terms of quantity and quality for oil and gas companies as well as investors and financial institutions.

We deliver prospects and play concepts that are new, overlooked, under-explored, or under-developed using our expertise in organic geochemistry combined with your geology and geophysical capabilities.

Worldwide Geochemistry is the leader in unconventional shale resource play and prospect evaluation. We can predict the best areas for either oil or gas production from shale and hybrid shale systems. We have the most extensive industry experience in shale-gas and shale-oil systems exceeding 30 years with production geochemistry on the Monterey, Bakken, and Barnett shales since 1982. 

While we are most frequently recognized for our seminal work in the Barnett Shale for shale gas development with Mitchell Energy, our work in the Monterey and Bakken shales predate even the Barnett Shale work.  However, praise be to Mitchell Energy for making shale resource systems a national treasure.  Overall, our shale resource system expertise was nationally utilized to assess every commercial shale gas and shale oil system.  Similarly we have been involved in shale resource system evaluations in Europe (UK, France, Spain, Germany, Hungary, Romania, Poland, Ukraine, Lithuania, and Russia), Middle East (Saudi Arabia, UAE, Oman), Africa (Algeria, Libya, Morocco, Nigeria, Uganda, Kenya, Tanzania, Namibia, South Africa), South America (Colombia, Ecuador, Peru, Bolivia, Uruguay, Brazil, and Argentina), Asia (China and India), Australia and New Zealand.

We can also assist in analytical protocols and sampling procedures for conventional and unconventional wells as well as interpretation of the analytical data.

Julie C. Jones

President

 

Julie Jones has extended experience working in geochemistry having worked at Humble Geochemical Services with Dan Jarvie. She gained experience in the geochemical laboratory preparing rock samples and operating Rock-Eval instruments. She managed sample login for the lab after completing high school. Mrs. Jones then pursued other interests in the computer and technology field. She worked seven years studying databases, web design and network management before returning to Humble Geochemical Services to help with database management software implementation and customer reporting. She also has handled the various geochemical studies available from Humble Geochemical Services. In 2007, she continued to work for Weatherford Laboratories leaving and joining Worldwide Geochemistry at the end of 2008.

At Worldwide Geochemistry, she is project manager for consulting projects, research activities, and database development. She has developed an unconventional shale resource database that is available for purchase from Worldwide Geochemistry. Mrs. Jones also manages all accounting and financial analysis for Worldwide thus bringing technical and financial knowledge to the business.

In February 2012 she presented the history and geochemistry of the Humble Salt Dome field, northwestern Harris County, Texas at the annual meeting of the Petroleum History Institute. She collected oil samples for geochemical fingerprinting and assembled both the historical and geochemical record of the field. This paper is available in the Petroleum History Institute’s annual journal.

She is also in charge of operations for Wildcat Technologies, the manufacturer of the HAWK pyrolysis instrument. 

Daniel M. Jarvie

Petroleum Systems Analyst

 

Dan Jarvie is a petroleum systems analyst specializing in assessment of unconventional shale resource systems.  He has studied or been involved in evaluation of both conventional and unconventional petroleum systems around the world including Europe, Africa, Asia (China) and Australia.  His work on these systems includes complete source rock analysis and assessments as well as detailed assessment of gas and oil. 

Mr. Jarvie’s work history includes both laboratory analyses and interpretive assessment of these data.  He has published papers on basic source rock characterization, source rock kinetics from open and closed systems for bulk and compositional kinetic parameters, detailed light hydrocarbon analyses, Williston Basin oil and source rock systems, organoporosity-nanopore imaging in association with the Bureau of Economic Geology at the University of Texas, identification of bypassed pay zones, catalytic activity, producibility assessment including pre-drill GOR and API gravity estimations, and numerous papers on unconventional shale gas and shale oil/hybrid resource systems.

He founded Humble Instruments and Humble Geochemical Services in 1987, which were sold to Weatherford International in 2007.  From 2008 to early 2013, Mr. Jarvie worked as a consultant to industry and taught geochemistry classes relevant to unconventional shale resource systems.  He spent 2009-2010 as visiting scientist at Institut Français du Pétrole (IFP) in Rueil-Malmaison, France, where he worked on compositional kinetic modeling with Francoise Behar and shale resource systems in Europe.  From 2013 to 2015 Dan was the Chief Geochemist at EOG Resources, the leading producer of oil in the onshore lower 48 states.  He is also an adjunct professor at Texas Christian University (TCU) and a member of the TCU Energy Institute Advisory Board.

He served in the U.S. Navy from 1969-1975 and was assigned communications responsibility for the Commander, Pacific Submarine Fleet, Pt. Loma Naval Station, San Diego primarily on the USS Sperry AS-12, but also with duty at Treasure Island (San Francisco), Norfolk, VA and Charleston, SC. 

Mr. Jarvie earned a B.S. from the University of Notre Dame and was mentored in geochemistry by Wallace Dow and Don Baker of Rice University.  He is a member of American Association of Petroleum Geologists, Rocky Mountain Association of Geologists, West Texas Geological Society, American Chemical Society-Geochemistry Division, Society of Petroleum Engineers, The Society for Organic Petrology, and European Association of Organic Geochemists.

Albert Maende

Applications Geochemist/Geologist

 

Albert Maende has 24 years experience in geology and geochemistry.  He integrates and interprets geochemical data for clients of Worldwide Geochemistry.   Albert has an M.Sc degree in petroleum geology that he obtained from Aberdeen University in Scotland after completing his undergraduate course at the University of Nairobi in Kenya.

His previous experience includes work on East and Central Africa Basins, not only at the National Oil Corporation of Kenya, but also with both Woodside and Ophir Energy Companies in Perth, Australia.  Albert relocated to the USA to work at Humble Geochemical Services where one of the studies that he worked on was a study of 13 sedimentary basins of the Rocky Mountain region.  He prepared geochemical logs of various wells in the study demonstrating areas of interest for producible amounts of gas or oil.  He previously worked as a geologist-geochemist at Weatherford Laboratories for four years, where he worked on the geology and geochemistry of shale gas, shale oil and conventional oil prospects on various resource systems in the USA and worldwide.
