The current technology for drilling oil and gas wells is limited to using neither jointed pipe or coiled tubing. Reel revolution Limited have developed the Revolver: an API certified rig combining the benefits of coil tubing drilling with the ability to rotate the coil up to 20 RPM.... Clockwise or Anticlockwise.
In addition... the revolver is equipped with a snubbing unit which means it is entirely self-sufficient and can prepare and complete wells underbalance and overbalance. The Revolver is capable achieving the ultimate underbalance drilling goal of... "Underbalance for the life cycle of the well"
Watch video for more illustration:
The technical background:
The revolver will be rigged up and operational within six hours of arrival upon location. The revolver is ideally suited to underbalance drilling with the enhanced well
Control features presented by coil tubing drilling. But it is not limited by frictional lockup, hole cleaning issues, and waits to be transferred. In addition, the revolver uses the existing BHA technology, therefore, driving down the price and raising the efficiency to levels never ever experienced in our industry before. The revolver trips four times faster than a conventional rig utilizes the same crew sizes as traditional coil tubing drilling operations and enables coil tubing drilling to overcome the limitations that have been holding back its implementation.
The revolver can be used with any underbalance separation unit. The heart and soul of the unit is the counterbalance in reel unit. The effective weight of the reel will vary as the coil tubing is pulled into and out of the well. The counterbalance moves automatically to maintain the hole assembly in perfect dynamic balance. Reel revolution have also developed a fully integrated UBD equipment components installed on a single trailer which brings enhanced efficiency to the revolver, reduces rig up times and crew sizes. The BHA can be deployed as the example using a lubricator for underbalance applications.
A number of BHA options are available from standard ppm applications using either the mud pulse technology or EMWD options for a variety of drilling applications.The connection to the coil tubing is made and pressure-tested. The BHA is run into the well to begin drilling. When tubing rotation is required, the reel and therefore the coil tubing can be rotated up to twenty rpm. If reactive torque is an issue, then the reel can also be rotated to the left. While directional drilling, rotation can be halted to achieve the necessary change in well trajectory. Once the necessary correction has been achieved the tension section can then be drilled. All of the tripping drilling is performed without connections thus maintaining steady-state downhole pressure conditions and preventing downhole pressure transients from potentially damaging the reservoir and negating the benefits of underbalance drilling. "The revolver is truly an underbalance drilling machine"
I really appreciate this wonderful post that you have provided for us. I assure this would be beneficial for most of the people.
