ABSTRACT:
Improved equipment and methods for treating wells by processes such as acidizing, gravel packing, and the like, wherein provision is made for removing the excess acid, gravel, and the like, from the well while the work string or pipe, on which the equipment is run into the well, remains connected to the well packer. The pipe string is disconnected from the packer only when it is ready to be removed from the well. Provision is also made for repeating the cleanout operation any number of times, making it possible to perform a series of treating operations during a single trip into the well and removing the excess treating medium after each such treating operation in the series.
