Confidential Survey of GasGun™ Customers

J Integral has compiled a database, Table B, of all the GasGun applications performed prior to July 2003. In this data, names of operators, lease names, and well locations are confidential. The wells in Table A are duplicated in Table B. Although the individual well data in Table B is not as complete as the data in Table A, it is included to illustrate the range of applications and results of the tool.
