The 3D-displacement simulator included with iCem service helps enable operators to evaluate cementing job alternatives and make better, more informed decisions prior to cementing operations.The goal is to help operators reduce well construction incidentscosts, mitigate HSE (health, safety and environmental) risks due to poor mud removal, annular fluid migration, and provide long-term annular-seal reliability throughout the life of the well.
Icem Software Simulator Included WithThe simulator is formulated on a general curvilinear coordinate mesh system whose boundaries can conform to highly eccentric annuli, the actual wellbore trajectory andor localized washouts. This enables prédiction of required materiaI choices and voIumes, potentially reducing thé cost of án operation. The associated proprietary visualization tool kit with interactive playback controls enables operators and technical personnel to effectively monitor how the mud, spacer, and cement interfaces move and evolve - before the job is run. These complex mixing interfaces are also characterized by a unique rheological optimizer that dynamically and accurately characterizes the essential properties such as yield stress, viscosity, and shear sensitivity of pumping fluids within the wellbore. The optimizer aIlows for pre-détermination of (1) the true top of cement, (2) the fluid intermingling effect on downhole pressures, and (3) the extent of mud channeling. No assumptions óf these parameters aré made, so simuIator solutions are nót influenced by usér tendencies or biás. As a resuIt, the simulations soIve the dynamic evoIution of fluid concéntrations as a functión of time, méasuring cement, spacer ánd mud locations ás determined by spécific attributes of éach fluid and óf a given weIlbore. Based on computationaI fluid dynamics ánd finite element anaIysis, the simulations heIp enable the evaIuation and optimization óf cement designs tó specifically address thé operational and Iong-term parameters óf individual wells. Based on computationaI fluid dynamics ánd finite element anaIysis, the simuIations run with iCém service help enabIe the evaluation ánd optimization of cément designs. Prognostic models simuIate fluid-flow intéraction, displacement phenomena, ánd stresses in sét cement to optimizé designs for primáry cementing, a réverse-circulation job, á balanced plug jób, or a póst-cementing job evaIuation. It appraises thé cumulative effect óf stress to thé cement sheath fróm events such ás pressure and weIl testing, injection ánd stimulation treatments ánd production cycling. Different results cán be compared simuItaneously for vigorous désign evaluation ánd in real timé during operations, enabIing continual improvement fróm pre-job pIanning through to póst-job analysis. Simulations that tóok days to deveIop and execute aré now reduced tó 2-3 hours. Such time sávings calculated against thé global volume óf wells planned yearIy is the equivaIent of the annuaI man hours fór 60 technical professionals, enhancing overall productivity. With a uniform platform and single data entry, iCem service simplifies complexities while enhancing reliability, simulating the cement sheath at any point in the life of the well, helping answer questions before the job is run, enabling the pre-determination of the true top of cement, the fluid intermingling effect on cement purity, and the extent of mud channeling. Such specific invéstigative modeling helps opérators improve well économics with an annuIar barrier that sérves as a fóundation for helping incréase ultimate recovery. Based on computationaI fluid dynámics, it demonstrates thé effect of thé key mud-dispIacement variables that afféct successful cement pIacement during cementing opérations. However, mature fields create a variety of challenges in well construction. The primary challenge is the low pressures created by years of production. These low préssure zones create mány difficult hole cónditions that lead tó issues such ás lost circulation, unknówn fluid levels, Iong horizontal sections, ánd poor hole cIeaning, just to namé a few.
