Successful fullscale verification of the ReelWell drilling method

The full scale verification of the drilling method was performed at Ullrigg, IRIS laboratory in Stavanger. The verification covers the required tools and equipment supplied by ReelWell and sub-contractors, and the operational procedures for a proper operation of the ReelWell Drilling Method.

The verification program is extended compared to previous testing, and covers the required steps in order to qualify for an onshore pilot test. The main goal for the full scale prototype verification is to demonstrate the practical application of the method and to check for proper operation of the tools and components when acting together. The following presents the equipment arrangement and the result from the verification program.  

Technology

The ReelWell Drilling Method is a new solution to improve the drilling performance beyond what can be achieved with conventional drilling. The main features of this new patented drilling method are:

• Improved down hole pressure control:

       - Managed Pressure Drilling with improved safety
       - Barrier to avoid  lost circulation
       - Improved safety by downhole well isolation

• Improved drilling process control:
       - Hydraulic Weight On Bit
       - Unique hole cleaning
       - Minimum skin effect

• Extreme horizontal reach capability
• Simultaneous drilling and running liner
• Optional downhole expansion of  liner for mono-diameter wells
