About This Product
This publication contains analyses of formation water from more than 2,600 wells in Railroad Commission of Texas Districts 1, 2, 3, and 4, encompassing 65 counties in South Texas. This is a USB (flashdrive) produced in 2018, replacing the ring binders of the original.


Keywords: formation water, resistivities, Rw, South Texas, Texas
