Paper Number: SPE-206215-MS
.... In the latter case, paraffins, asphaltenes, and scale, collectively referred to as "schmoo," progressively build in the flowline and reduce the internal diameter, limiting flow rate capacity. One cost-effective method to remediate flowlines with significant deposits is coiled tubing (CT) cleanouts...

... on using the field data from the Montney and Duvernay formations along with laboratory data and numerical modeling to understand the hole cleanout associated with through-tubing drillouts of frac plugs. Initially, an extensive full-scale flow loop laboratory testing program was conducted to obtain data...

... such example is the operational difficulty and costs incurred in dealing with proppant flowback after fracturing operations are completed. In many such cases, a post-fracture cleanout is required before turning the well over to production, and subsequent additional cleanouts can be required after three to six...

... cleanouts using conventional coiled tubing (CT) and nitrogen had been unsuccessful. The job had to be performed from a work barge in a catenary style, meaning that the injector head, blowout preventers, and power pack were on the platform, but all were operated from a barge. The advanced wireless catenary...

... Abstract Bauxite ceramics are a high strength proppant, which is often used for fracturing stimulation in deep and hot wells. Due to its higher specific gravity (3.5 – 3.6), it is very challenging to design and execute the post-fracturing proppant cleanout with coiled tubing (CT) successfully...
