Abstract
An apparatus for wellbore treatment includes a tubular with one or more solid, erodible blocks on its outer surface. The blocks carry a chemical for wellbore treatment that is released in the wellbore by erosion of the blocks against the wellbore wall. A method for wellbore treatment employs the tubular to release the chemical in the well by erosion of the blocks.
