Thru tubing solutions for downhole operations
Posted by AllmaJess on November 5th, 2014
Downholes are safety valves used as a failsafe mechanism for oil wells. They help in preventing accidents from uncontrolled release of oil. Thru tubing procedures are followed to build these downholes and you require specialized equipments and machinery for this. Downholes are uni-directional valves with flaps that open downwards. During overflow of fluid they close and prevent the fluid to reach the surface. Their location is generally optimized keeping in mind the safety concerns in an oil extraction operation. Thru tubing Grande Prairie helps you to achieve all this and much more with accuracy and efficiency.
Proper thru tubing requires some important precision tools. Mills are available in many shapes like concave, convex, tapered or flat-bottom. Customized mills can also be produced as per your requirement. You only need to give your specifications to the company and your order would be executed. A blade centralizer makes sure that there is maximum mud displacement during cementing process in the wells. Its unique design demands lower rotational torque thus enhancing efficiency. Thru tubing Grande Prairie companies keep a long list of other related tools like hydraulic jars with a bi-directional design for both up and down movement that are most suitable for coil tubing operations and fishing and wellbore cleanout.
Mud motors used in thru tubing Grande Prairie are also used in wellbore cleanouts and fishing as well as plug and cement milling. They are tough machines that can operate in adverse conditions for long hours. They can easily withstand repeated jarring and side loading. Coil connectors are used to attach the BHA with the coil tubing alongside maintaining the seal at very high pressure. They are also resistant to repeated jarring and huge amount of torque. Dual flapper check valves of thru tubing protect the surface pumps against any back pressure and prevent flow from the wellbore.
Heavy duty disconnect in thru tubing eliminates fluid circulation during excess pressure. They constitute an essential part of the motor head assembly along with a dual flapper check valve and dual circulation unit. Dual circulation units use a dropball to prevent damage by diverting the fluids to a mud motor. It has another part called the Burst disc which is ruptured to resume the circulation of the fluid. To remove the debris, fills and obstructions in a wellbore during thru tubing Grande Prairie, a Venturi junk basket is used. It deploys vacuum to remove debris of all sizes. At the bottom of the basket there are catchers that trap the debris.
Thru tubing involves major tasks like wellbore cleanout to remove the sand and fills to ensure maximum production and no obstruction, recovery of the well bore debris, preparation of the well by stimulation etc. For these purposes, harsh and rugged machines have been designed that can ease the process of milling plugs and valves. Thru tubing Grande Prairie companies offer alternatives to dangerous methods like explosions through cutters and perforators. The professional team associated with this machinery is trained to tackle any situation and hazardous scenario. You can easily contact the company for the tools or their assistance through their website. Always go for licensed workers who have an original permit from the authority.
