Paper Number: SPE-216158-MS
... (internal phase) which is mixed with an atomizing tee (also known as a foam generator) that mixes the liquid and nitrogen homogeneously to create a stable foam. Due to the gas's compressibility, foam quality will vary throughout the tubulars and annulus during a cleanout. When pumping, friction...

... improvement over conventional rig/hoist cleanout operations, it is the latest advancement in JetSweep technology. Sand production is big challenge in PDO. During conventional tubing cleanouts, significant losses at the reservoir is encountered. As a result, conventional cleanout operations using hoist pumps...

Paper Number: SPE-211289-MS
.... The objective intended in the case studies performed in the Middle East and South Asia was to perform cleanout in scenarios where incumbent tools had failed in the past. The impact of jetting action in cleanout operations decreases with an increase in stand-off distance. It was confirmed from laboratory tests...

Paper Number: SPE-197212-MS
... Abstract Coiled tubing (CT) sand cleanout has been a normal practice for offshore wells, and repeated cleanout runs will have to be done over the years to sustain production. It has been observed that the production period of these offshore wells has shortened significantly after each cleanout...
