Petroleos Mexicanos (Pemex) has found a new way to produce heavy oil from pumping wells. The key component is a bottom-hole stuffing box which reduces the friction of the pumping string during the downstroke. The relatively simple system has already proven successful in the Ebano-Panuco area of Mexico, where Pemex produces highly viscous oil (10/sup 0/ to 14/sup 0/ API). Basically, the Pemex method consists of a special downhole stuffing box and polished rod anchored at the end of the pumping string. The isolated tubing is filled with water to minimize friction, and the heavy oil is produced through the annular space located between tubing and casing strings.
