During the production of crude oil, naturally occurring paraffin can be deposited on the inside surfaces of production tubing. These wax deposits reduce the cross sectional area of the tubing and can reduce or completely halt the flow of oil from the well. Currently there are many different methods employed in oil fields around the world to combat paraffin problems, but none are one hundred percent effective. When the available methods fail completely, costly removal and replacement of the tubing must be performed in order to resume oil production. The hot anti-wax knife tool provides a previously unavailable method of melting a hole through the paraffin deposits in the production tubing in order to restore production. The tool utilizes rechargeable batteries in a novel arrangement which provides sufficient power to melt through paraffin using a uniquely designed heating element and cutting head. |
