Petrophysical Training Classes
  • Class capacity is limited to 12 people. Generally classes are open until they are posted full at this site. Special in-house seminars are available, however admission is determined by the company sponsoring the training at heir office. Contact our home office, for a reservation and pricing information, if you wish to attend. Based on customer demand the following sites are typical for training courses. If you desire HDS training in your area let us know. We will poll our customers in your city and might be able to make it economically feasible to do a class there:
  1. Houston, Texas
  2. Denver, Colorado
  3. Calgary, Alberta, Canada
  • In house Training at your office In North America, Europe or Asia can usually be accommodated with a minimum of 4 students or a negotiated flat fee.

Log Data Processing Includes Log Digitizing, Las or ASCII data import and generally any type of data posting relevant to the HDS Log Analysis Program.

  • Log Digitizing from Paper copies into HDS binary or LAS
  • LAS or ASCII file import including Tops and Perfs.
  • Petrophysical Analysis is a separate service (see its page).
  •  All work is done in-house with the current version of the HDS Log Analysis Program using a combination of senior staff members, programming personal and technicians.
There are several Petroleum Engineering firms which use our software for log interpretation.  These firms are generally better suited for a complete reservoir evaluation and we can supply you their names.  In some cases we will take on small jobs in order to help our customers.  This is service on an as needed basis and is not intended as a long term contract.  We try to focus most of our attention on software development.    We will tell you up front, if we feel there is another company better suited to evaluate your particular project.
