COROD Continuous Rods and Well Services


COROD Feature Image

Deviated well configurations can increase sucker-rod and tubing failures caused by coupling and tubing wear, which leads to considerable down time. 

Weatherford COROD® continuous sucker rods require couplings only at the top and bottom of the rod string, regardless of well depth. With fewer joints, this solid length of steel is lighter and eliminates many premature tubing failures, especially in directional and horizontal wells.

COROD Products setting up

Our COROD continuous rods optimize reciprocating rod lift (RRL) and progressing cavity pumping (PCP) applications.

A superior alternative to conventional sucker rods, COROD continuous rods offer lighter weight with higher-quality materials, only two couplings, more space in the rod-tubing annulus, and integrated services. This translates to maximum efficiency and lower operating costs.

We produce COROD continuous rods with high-quality materials and strict quality control in our state-of-the-art manufacturing facilities.

Our integrated COROD systems can include comprehensive installation services, which include quick mobilization, high levels of automation, and advanced transportation solutions.

COROD running equipment

Unlike conventional sucker rods, which are coupled every 25 or 30 ft (7.6 or 9.1 m), COROD continuous rod requires couplings only at the top and bottom of the rod string, regardless of well depth.

This innovative solution reduces pin and coupling failures by decreasing the number of threaded connections, thereby minimizing the potential for rod string failures and costly well interventions. With more uniform contact loads and a lighter weight that reduces torque and power requirements, COROD continuous rod also extends the lifespan of tubing.

The COROD design extends the lifespan of rod and tubing strings, which delivers superior performance compared with conventional rods in deviated wells. Converting to COROD rods can result in lower required horsepower per barrel pumped, higher mean-time between failures (MTBF), and a larger annular space to minimize pressure losses.
