Tensleep Formation Fracture Study Compendium – A summary of three and a half years (2007-2010) of field, outcrop and core studies on the Tensleep Formation for the Enhanced Oil Recovery Institute at the University of Wyoming.  The report is available by request at www.eori.uwyo.edu or as a pdf within our FractureStudies database Tensleep Formation Fracture Study Compendium.

 

Fracture Studies done by John C. Lorenz and Scott P. Cooper provide insight and solutions for:

  • Fracture-controlled reservoir flow dynamics
  • Fracture-controlled production behavior
  • Better well placement
  • Better completion techniques
  • EOR activities
  • Directional drilling
  • Structural interpretations and tectonic histories
  • Increased ultimate recovery

Why do fracture analyses?

1. The advantages and importance of knowledgeable fracture analysis:
Fractures are easy to count and to measure for dip and strike, but that does not make them simple, easy to understand, or interpret. Unless the fracture types are understood, statistical analyses of fractures are meaningless. There are many types of fractures, and each has different effects on reservoirs. Fractures vary by lithology and by stress regime, and can either enhance or degrade reservoir permeability. Many types of fracture permeability can change during production.

2. Why this fracture-analysis team is unique:
Fracture analysis requires insight into fracture type and origin in order to make valid three-dimensional assessments of fracture-related reservoir plumbing, and to reconstruct structural/tectonic histories. We offer more than the measurement and counting of cracks. Our long history of helping to develop the science of natural and induced fracture interpretation and analysis (see publications list), and our experience in a diverse array of fractured reservoir plays and formations, allow us unique insights into fractured-reservoir characterizations and problems.

3. Multidisciplinary interactions:
We have a proven record of providing useful, applied geological data and concepts to multidisciplinary teams--please note the themes of our published papers and the different expertise of the various co-authors. We have interacted successfully and productively with engineers, geophysicists, petrophysicists, rock mechanicists, and other experts.

Aerial photography, and geology of production and analog areas:
John Lorenz, as a licensed pilot and flight instructor, can provide aerial images from overflights of your producing areas or analog site, field scale and aerial scale geologic assessments, or teach you how to fly. Contact John for further information.

List of publications:

A partial list of our publications is attached here as a PDF.

Two papers published in the American Association of Petroleum Geologists Bulletin (one on fractures within the Spraberry Formation the second on a fracture model based on Teapot Dome) are provided here with permission from AAPG as locked PDFs. Additional publications are available through the AAPG at www.aapg.org.

Our publications with the Department of Energy are available through the DOE’s Information Bridge website at www.osti.gov/bridge/. This site provides free public access to all of the DOE’s Scientific and Technical publications.

We provide several of our public-domain reports including nine Multiwell Experiment Project Reports as PDFs in our Fracture Studies/Clients page. We can provide additional articles, papers and reports on request.

Strategic Partners:

Dr. Ahmed Ouenes

FractureStudies has for years co-taught classes on fractured-reservoirs and worked joint projects with Dr. Ahmed Ouenes of FracGeo (www.fracgeo.com). Dr. Ouenes and FracGeo have unique capabilities in fractured-reservoir modeling using Continuous Fracture Networks and are currently breaking new ground in the understanding of the interactions between natural fractures and hydraulic stimulation fractures.
