Objetivo The aim of the project was to bring innovative extensions to an existing commercial gas kick and well control simulator, SideKick. The enhanced simulator, UNIKS (UNIversal Kick Simulator), incorporates new physical models resulting from research at Schlumberger Cambridge Research and BP. Its use will improve the effectiveness and safety of drilling operations.The project demonstrated that UNIKS accurately simulates a wider range of field conditions, in particular slim-hole, high deviation and horizontal wells. The project also demonstrated that UNIKS can accurately simulate the processes involved in under-balanced drilling and that it can be used to develop safe methodologies for this technique. Under-balanced drilling reduces formation damage, enhances production, and can make exploitation of otherwise marginal fields economic, resulting in an enormous increase in recoverable reserves.L%SideKick version 2.0. released end June 1995.SideKick version 2.1. released end December 1995.SideKick version 2.2. released January 1997.A comprehensive kick and well control simulator, UNIKS (UNIversal Kick Simulator), has been created by incorporating the following innovative technologies into an existing gas kick simulator, SideKick :* A newly developed slim hole frictional pressure model which accurately models the large frictional pressure drops in the small annulus outside the drillpipe, and takes into account the subtle effects of rapid drillpipe rotation used in slim hole drilling.* Gas migration correlations for slim hole annuli and for deviations up to and beyond the horizontal. These are the results of recent experimental campaigns in full-scale flow loops.* The capability to model multiple phase (gas, oil, brine, and oil with dissolved gas) influxes from multiple or long producing formations. The existing simulator models only a gas influx, occurring at the bottom of the well. (Only partial inclusion)* Modelling of wellbore compliance and fluid loss into permeable formations. Inclusion of these parameters has been shown to be essential for accurate prediction of surface pressure variations when the well is shut-in.A sophisticated kick simulator has many applications in well planning; for example casing point selection, kick tolerance calculation, sizing of degassers. During the drilling of a well "what-if?" scenarios can be simulated to verify and update the drilling and contingency plans. Post-event analysis of kicks through simulation is important in order to learn from mistakes and apply this knowledge in the future, a major concern for regulatory bodies, but also operators. A kick simulator has uses in training, and drilling contractors have developed training packages from the results of kick simulation, and modified well site operating procedures accordingly.For the user of the technology, the additional cost compared with the existing conventional simulator, SideKick, will be small. Current SideKick users will receive a UNIKS upgrade, as part of the SideKick annualmaintenance agreement.Application of the technology can lead to safer drilling practices and better well plans. If this contributes to prevention of a single blowout, the cost and energy savings will be many millions of dollars.
