... it is intended. It is coiled over a drum (referred to in the paper as a spool) with more than 25 full layers around the bed wrap and has a high amount of energy stored in it because of the residual bending of the CT material. Although the string is secured at the end with an industry-specific clamp, close...

All CT strings in the study conducted by Rispler et al. have similar erosion-rate trends as the string presented in Fig. 2 . As the first 270 meters of the tubing is on the bed wrap of the reel, the upward trend in erosion rates...

...-tubing failures indicated that fatigue was not the only failure mechanism. Examination showed that 90% of the failures occurred on the bed wrap of the CT where little fatigue had accumulated. It was concluded that external corrosion must be eliminated, or at least minimized, to achieve the expected...

Wrap angles up to 360 degrees help with stability, however high wrap angles can block cuttings when tripping out of high angle holes with rotation and pumps off, if there is a cuttings bed...

The slurry flow regime in the annulus results in continuous sand production until a stable bridge and later a stable sand bed is formed on top of the tubing deployed scab liner screen. Moreover, results showed that the main pressure drop happens across...

With self-suspending proppant technology, fluid sweeps are eliminated because proppant maintains efficient transport characteristics and forms a higher, more uniform settled bed height compared with proppant transported...
