Abstract
The need to have the housing of an ESP suspended by the discharge flange to allow room for downhole thermal expansion in a situation where there is no surface access to the lower end of the ESP when the discharge flange is bolted up is addressed by building the ESP on a support that is removable downhole without intervention. A controlled electrolytic material or CEM can be used or other materials that meet the structural support requirement for the ESP and then after a predetermined time lose their capacity to support leaving the ESP suspended by its discharge flange and capable of growing under thermal loading.
