Abstract
The slim hole drilling technology satisfies the oil and gas industry demands todays. As it offers not only a significant cost reduction but also minimize the environmental impact generated from the drilling operation. Slim hole drilling technology has been impeded by the lack of documentation of well control methods for small annulus drilling. One of the major barriers to the introduction of slim hole drilling technology to oil field operations was perceived to be the maintenance of safe standards of well control. This research introduces a simple analysis of the pressures undergone by the well bore during killing operation so as to drive a new killing model for the slim hole wells. The developed model takes into consideration the different factors affecting kick control of slim hole well like the annular pressure loss, well inclination, drill string configuration, and finally kill rate. The research presents the Dev-model that can be used during the kick control of vertical, deviated and horizontal slim hole wells also through the research. It is proven that this model can be used successfully with the vertical, deviated, horizontal conventional wells especially those that have weak formations at the open hole sections. For the slim hole wells, the Prince and Cowell modified conventional approach5 is an alternative but it does not take into consideration the drill string configuration or the well inclination. Other alternatives but used mainly with the conventional wells as they do not take into consideration the annular pressure loss, are the vertical kill sheet and the deviated kill sheet. The validity of the model was checked by comparing with other models at different well types with different drill string configurations. It was concluded that the Dev-model could be used accurately during kick control situations not only in all slim hole wells but also in all of the conventional wells.
