Paper: ELASTOMERIC COMPOUND SELECTION CRITICAL TO IMPROVED CASING PLUNGER SUCCESS

The first ever actual field tests to evaluate well bore fluid's real time impact on elastomeric compounds used for casing plunger sealing cups led to major breakthroughs in the discovery of better sealing cup compounds, previously unavailable to the industry. The drastically improved performance of carefully formulated compounds, coupled with radical innovations in over-all casing plunger design, were major factors in the development of the first truly successful casing plunger, following decades of disappointment experienced with previous casing plungers on the market. Field data, photos, and procedures will be discussed and state of the art products presented.
