About Us


About Applied Stratigraphix

We are a US-based consulting and training firm specializing in Structural Geology, Sequence Stratigraphy, Seismic Stratigraphy and Sedimentology services for the oil and gas and mining industry. This includes consultation in fracture description and modeling, fault-seal analysis, seismic interpretation of structural styles, core description, seismic facies analyses, carbonate thin-section description, seismic interpretation, petrophysics, and exploration and development of shale plays. We have experts who specialize in both conventional and unconventional reservoirs. Contact us today for a free initial consultation on your sub-surface data.

Our locations

Our headquarters are twenty minutes away from downtown Denver and half an hour from the largest core facility in the United States. Or field office in Ouray allows us quick access to world-class outcrops in Utah and New Mexico.


Our mission is not to be the largest consulting firm, but to be your training and service provider of choice.


Since our inception we have tried to establish long-term relationships with our clients. It takes years to establish a reputation and our vision is to have life-long clients that trust us completely based on our track record.


  • Globally Mobile:We have trained professionals worldwide – we have no geographic restrictions
  • Safety:We have been accident free on all our field trips since the establishment of our company
  • Environment:We ensure that no-one litters, and follow a ‘leave-no-trace’ policy on our field trips
  • Respectful:We ensure we treat ALL our clients with the same respect, irrespective of race, gender, ethnicity or experience-level
  • Affordable:We are not cheap, but very competitive. We strongly urge you to compare the cost of courses and field trips we offer with those of our competitors.

What makes us Different?


We are a group of consultants with a shared experience that spans over 20 countries and 60 oil and gas companies. All our consultants are multilingual and are used to working across cultural boundaries. All our consultants have either doctoral degrees or have over 30 years of industry experience.


We are part of a Geoscience Alliance in Colorado which allows us to offer expertise in areas well beyond sedimentology, stratigraphy and structural geology. Alliance members include iReservoir who provide seismic attribute, inversion, AVO, and geomodeling services, Borehole Image Specialists can tease out the sort of details most service providers cannot, Total Depth Geosteering can provide assistance not just in the US but overseas as well and Terra Chem Labs provide geochemistry lab services and oilfield solutions.


Unlike most of our competitors, we are a small company, and we use that to our advantage. We don’t deal with thousands of participants in hundreds of courses, and therefore you are not a statistic!

When you contact us, your e-mail is not answered by a secretary who has never met the CEO – its read and responded to by Dr. Jaffri, and that too within six hours.


We understand data limitations and the technical capacity of our clients. Instead of turning this into your weakness by taking advantage of you and offering false expectations we will provide honest advice. 

Our straightforward, 100% transparent business dealings, especially with companies in developing countries, set-us apart from most of our competitors.


Dr. Cédric John is a carbonate geologist with over 20 years of experience. His specialty includes geochemistry and diagenesis of carbonate rocks, forward stratigraphic modelling, and application of machine learning and deep-learning to geological and stratigraphic problems. He has conducted field research and field teaching in North America, Europe and the Middle East. Dr. John will be leading field trips to Oman and teaching in-house courses on carbonate diagenesis and machine learning.
