Barrier design and tailoring digital twin enables real-time job monitoring, evaluation, and instantaneous barrier validation
Talk to an expertiCem service enables engineers to make well informed decisions to tailor job design, cement placement, cement integrity predictions, and get casing safely to bottom. To design and place effective barriers, iCem service evaluates safe casing placement, lost-circulation material (LCM) strategies with the Particle Wizard™ LCM software, and safe/optimum cement placement with 2D hydraulics and 3D displacement efficiency simulations to achieve the required top of cement (TOC).
iCem software models the intermixing of wellbore fluids in annular geometry, considering factors like casing movement, mechanical separation, turbulator centralizers, fluid rheology, standoff, placement rates, and density hierarchy. It predicts fluid displacement efficiency, even in reverse, to optimize shoe track length and cement integrity. The software models fluid concentration over time at all depths, including lost-circulation impacts, for optimum TOC prediction that results in a predictive CBL.
This solution provides predictive capabilities for well cement coverage, which can facilitate compliance with regulatory standards and TOC predictions. iCem service also enables rapid “what if” scenario simulations for informed decision-making and better operational predictability.
Operators can remotely access and monitor up to 20real-time variables from any location, enabling comprehensive job monitoring and data download in CSV format. The streaming of calculated variables such as downhole ECD and surface pressure allow for the evaluation of design performance against execution. This comparison enables instant TOC assessment based on a real-time pressure match assessment.
The iCem service 2D hydraulics simulator models wellbore hydraulic dynamics througout the cement application, which allows operators to predict well behavior under various conditions. By matching calculated and realtime surface pressures, the simultor ensures accurate downhole hydraulic predictions are accurate. crucial for zonal isolation and well integrity. This capability makes the modeled TOC predictions highly reliable, which is crucial for effective zonal isolation and well integrity.
The comparison of real-time and design/planning phase job performance is crucial to evaluate cement operations. Through pressure matching assessments and 2D fluid position modeling post-execution, operators can accurately validate the cement operation. This involves a comparison of real-time data (rate, density, pressure) with preplanned design parameters. Alignment of calculated and real-time surface pressures confirms the operation was executed as planned, verifying the modeled TOC and ensuring desired zonal isolation and well integrity.
