Paper: Sucker Rod Sideload and Wear in Deviated Coalbed Methane Gas Wells

ConocoPhillips San Juan Business Unit rod pumps more than 50 "S" shaped deviated wells. The load a sucker rod applies to the tubing wall is called sideload. Sideloads will be higher in the depth intervals of the tubing that are more deviated. The time requred to wear the sucker rod or tubing to failure should be a function of sideload. ConocoPhillips San Juan's "S" shaped rod pumped wells have shallow curved sextions that tend to have sideloads of one hundred pounds or greater, and many have been running for several years. ConocoPhillips presents sideload vs. running time data for their longer running wells, and learnings from two "S" well repairs completed in early 2012.
