New circumferential displacement cards optimize installed sucker rod string load carrying capability

摘要

You can optimize the load carrying capability of installed sucker rod strings by 15% with these new circumferential displacement cards, announces their maker.The company conducted an extensive engineering study to determine achievable load carrying capabilities of sucker rods using current displacement values. It was found that existing displacement values and corresponding displacement cards, at best, achieved load carrying results 9% less than design strength ratings for new runs; 18% less than design strength ratings for used rods.
