Velocity Survey Data

Our library of velocity survey data covers the U.S. Gulf Coast onshore from the Florida panhandle to the Rio Grande Embayment of South Texas. This data base includes most of RRC Districts 1-6 in Texas with some Permian and other areas.

These data are delivered via e-mail as a text file. The file can be opened and printed with most word processing programs.

We may not have the original velocity survey source data for all wells listed, time/depth calculations are based on third party interpretations of the original surveys. We assume no liability for the use of these data beyond the purchase price. If you have reason to believe a survey is unsuitable for your application we will credit your account for the amount involved.

Velocity surveys are $95.00 each (3 or more- $75.00 each). We will invoice your firm by regular mail.We do not accept credit cards.
