Abstract
A method for pneumatically transferring particluate solid materials into an earth formation penetrated by a well bore is shown. A gas is flowed into the well bore to establish the desired injection rate and pressure. A particulate solid material is then added to the established gas flow passing into the well bore by flowing a gas containing an entrained particulate solid material into the established gas flow to thereby transfer the solid particulate material pneumatically into the well bore.
