Baker Hughes introduced the CIRCA coiled-tubing software solution, which helps service providers and operators simulate, model, plan, and carry out coiled-tubing operations. It offers high model accuracy built on more than 3 decades of field-guided refinement. The software suite comes in three optional packages. The Complete package optimizes job designs and saves time, providing accurate modeling of tubing forces, pressures, friction losses, rheologies, fluid behaviors, and downhole tool operations. The Pro package allows providers to know the outcome before they start in the most advanced coiled-tubing operations. It includes modeling for complex capabilities such as solids transport, abrasive perforating, hydrogen sulfide effects and thresholds, and reverse circulation. The Real-Time package keeps simulated thresholds updated and on-track in the cab. Every model uses computational simulations and empirical data to identify job limits and opportunities. The user interface is made up of detailed, context-related help files, along with a warning and messaging system based on actual physical conditions and lessons learned. It provides immediate guidance to coiled-tubing providers and helps them operate to the limits of their equipment, safely and efficiently.
