Abstract

This paper is to highlight the engineering advance method had been successfully applied in Gulf of Suez, Red Sea, Egypt, well, January 2014. This new method enables to use the same slot for several slot recovery operations rather than only one slot recovery. The Deflecting Conductor Shoe is made as a subsea diverting tool. The conventional size ranging from 24” to 30” depending on the platform's dimensions and restrictions. Using a DCS with bigger sizes designed to match the platform's levels to result in the minimum angle at seabed, and to permit for conductor movement horizontally. Also to avoid the magnetic effect at the seabed a mechanical gyro used to determine Azimuth. The spacing between the conductors at the seabed is designed in pattern to allow for best anti-collision results, and more number of wells. The modification on the DCS is by the controlled azimuth of exit, the diameter and the new conductor inclination at the seabed. The most important feature in this design is the ability to engage with a spear from the inside in the future, and turn it to the desired direction considering collision with nearby wells, and with applying the method of drill and drive the risk of hitting nearby wells had vastly decreased and the ability to correct the well path increased by using motors. Using this design will push the platform life within the increased production and in the same time saves the cost to install standalone wells or to establish new platforms extensions which enhances the investment cost for wells on old fields. This means an overall revival of old platforms and old slots whilst making the best use of reservoir potential reserves which were difficult to be achieved with minimal cost. Using this new design, each slot on the platform can be used for multiple slot recoveries, up to five. This design is a modification on the methodology of using the DCS tool which is still conventionally used by major Oil and Gas companies.
