... Abstract Current commercial dissolvable plugs have been found unsuitable when we hydraulic fracture extremely HTHP wells, especially with acid. Dissolvable alloys, the most popular materials, react too intensively in acid environment, and nearly all types of commercial protective coatings have...

.... We hypothesize that the NGL is spontaneously and forcefully imbibed into the oil-saturated core plug, displacing the oil, resembling a counter-current surfactant imbibition process. However, due to strong solubility of NGL in oil and the active hydrocarbon component's extraction mechanism...

... in the gas condensate subsea tieback. A hydrate kinetics model is coupled with a dynamic multiphase flow simulator to predict when and where hydrate blockages occur during the transient operations of the subsea tieback. The predicted location of hydrate plugs has also been determined to further guide...

... with the high risk of plugging the downhole tools, which would cause a more complicated operational situation such as the inability to manage loss and well-control situations with catastrophic HSE events. Traditional lost circulation technologies are granular in nature and require large amounts of solids...

... -with and without surfactants- were injected from the opposite end of the core plugs to simulate the forced imbibition of fracturing fluid along with hydraulic fracturing in real field operations. Finally, the injection of crude oil was resumed from the original end of the core sample to establish the flowback...

... Abstract Managing asset retirement obligations efficiently and effectively is an important objective for operators. Nowadays, Many operators are looking for additional guarantees before and during plug and abandonment (P&A) procedures to properly decommission the wells and permanently seal...

... Abstract The paper focuses on the use of dissolvable plugs in plug and perf completions, which allows the frac operations to be carried out, isolating between stages, and when the job is complete, the well can be flowed-back immediately. The need to mill out as with conventional plug...

... scenarios. Traditionally, a deep plug set by slickline is used as the first barrier and Tubing Retrievable Surface-Controlled Subsurface Safety Valve (TRSCSSV) act as the second barrier prior nippling down of BOP. To enable full-fledged interventionless approach, a barrier-rated tubing hanger valve has been...

... Discrete Element Method (CFD-DEM) model to simulate the fiber-laden fluid flow process in millimeter-wide fractures. The effect of fiber concentration, fracture roughness, and fiber stiffness on plugging capability is evaluated. It is found that, although fibers are known to create net-like structures...

... Abstract For almost a decade, the predominant completion drill-out bits utilized to drill composite frac plugs were roller-cone (RC) bits incorporating "hybrid" cutting structures. RC hybrid cutting structures consist of various layouts incorporating a combination of milled teeth (MT...

... include fracturing plug failure, under/over stimulation and adverse well performance as stated in published literature. This paper addresses plug effectiveness and impacts on production, fracture geometry and well spacing using a historical review of fracturing plugs and a simulation-based approach. Using...

..." wells in the same bench on a 2 well pad. Both wells were completed in the Spraberry bench with 60 stages (Well C) and 59 stages (Well D). Composite ball drop frac plugs were used for stage isolation on both wells. The wells were TD'd with 8.33 ppg drilling fluid (Well C) and 8.5 ppg drilling fluid (Well...

.... Retrofit multilateral technology allows use of slots with producing wells for drilling and completing new targets. In a retrofit multilateral well, the existing motherbore is temporarily plugged to allow for drilling of an additional branch. After re-completing the well, the existing motherbore and the new...
