Abstract
An electric submersible pump (ESP) intake system, apparatus and method is described. An ESP intake system includes a filtered intake section coupled adjacently to a sliding sleeve intake section, wherein the sliding sleeve intake section has a closed initial state and is selectively actuatable to an open position when the filtered intake section becomes at least partially clogged. An ESP intake method includes operating an ESP pump downhole in a well including abrasive-laden fluid, the ESP pump including a filtered intake section and an actuatable intake section, employing the filtered intake section as a first fluid entrance into the ESP pump, monitoring information from ESP sensors during employment of the first fluid entrance to identify clogging of the filtered intake section, and opening the actuatable intake section upon the clogging so identified such that the actuatable intake section serves as a second fluid entrance into the ESP pump.
