Heavy Oil / Pump to Surface
Title
Heavy crude oils provide an interesting situation for the economics of petroleum development. The resources of heavy oil in the world are more than twice those of conventional light crude oil. Lloydminster may be a small city, but the region has played a huge role in the development of technologies that are now spreading around the world. The first key was to use pump to surface equipment to produce the wells. Usually the candidate wells continually sanded in, had overburden collapse, or suffered from some other condition that had brought them to within one step of abandonment. Pump to surface equipment was a well-known service solution. The equipment was better able to pump bulk materials to the surface because the rod string was removed and replaced with a modified pump to surface pump fitted directly to the tubing. This “open bore” approach allowed sustained production of sand and other formation debris.
The Second key to Heavy Oil Production is the selection of surface equipment. The ICI GR-30 Hydraulic Pump Jack pumps the entire tubing string, eliminatingthe need for sucker rods. This technique allows for the effective operation in very high sand/debris content applications, as production is lifted to the surface through clean unrestricted pipe.
CONTINUOUS PUMP-TO-SURFACE JACKS

a. Name: The Golden Rod 30 Series
b. Application:
i. Permanent:
ii. Temporary
c. Description:
The Golden Rod 30 Series is an easy-to-operate hydraulic pump jack
that is capable of a 40,000lb lift. The GR-30 eliminates the need for
sucker rods, and instead reciprocates the entire tubing string to work a
large-bore downhole pump. This open bore approach allows for the
production of high volumes of liquids or formation solids at a very low
stroke rate.
