TubeFlow PIC for Well Intervention

TubeFlow PIC for well intervention offers several applications with primarily three modes of intervention, namely: coiled tubing, wireline, and drill string (jointed pipe). In addition, capillary strings are also modeled in hydraulics, tubing force analysis, and well unloading applications.

Coiled Tubing

• hydraulics - production, injection, and circulation operations with effects of choke pressure loss including temperature modeling
• tubing force analysis – lock up depth prediction, maximum set-down weight and overpull, surface weights during RIH and POOH
• pipe fatigue – useful life tracking during jobs and predicting number of trips to failure
• wellbore cleanout – models plug milling and drill-outs with or without wiper trips, aids in fluid selection and design of wash fluids

Wireline

• hydraulics - production and injection operations with wellhead pressure effects including heat transfer to/from the formation
• tubing force analysis – compression depth prediction, maximum set-down weight and overpull, surface weights during RIH and POOH and at weak point limits
• pump down analysis – models minimum required flow rate for wireline tool to reach target depth along with design flow rates such that weak point limits and maximum working tension are not exceeded

Drill String

• hydraulics - circulation operations with effects of choke pressure loss including temperature modeling
• torque and drag – lock up depth prediction, maximum set-down weight and overpull, hook load and surface torque during RIH and POOH, tubing stresses
• drilling – models cuttings transport in overbalanced and underbalanced scenarios accounting for production from reservoir
• gravel/frac packing – conventional and alternate path gravel packs, alpha-beta and alpha-alpha packing, estimate proppant and slurry volume requirements
• fluid displacement – transient wellbore cleanup in onshore and offshore wells
