Welcome to our fracture studies by website. This site details our decades of work with natural fractures and their implications to production. Please enjoy and contact us for additional information.

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. Some 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 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 overflights of your producing areas or analog site, provide aerial images, field scale and aerial scale geologic assessments, or teach you how to fly. Contact John for further information on these capabilities.

List of publications:

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

Two papers published 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 as locked PDFs. Additional publications are available through the AAPG at http://www.aapg.org.

Our publications with the Department of Energy are available through the DOE’s Information Bridge website at http://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.
