Methods And Systems For Deploying Cable Into A Well

Abstract

A system for deploying cable that includes a housing. The housing is configured to receive circulating lubricant, and a drive assembly is located within the housing. The drive assembly includes a first gripper portion and a second gripper portion. The grips portions are supported by independent frames. An actuator is connected with one of the frames. The actuator provides force that causes the gripper portions to engage and cooperate to support and deploy cable.

What is claimed is: 
     
         1 . A system for deploying cable, wherein the assembly comprises:
 a housing, wherein the housing is configured to receive circulating lubricant; and   a drive assembly disposed within the housing, wherein the drive assembly comprises:
 a first frame supporting a first gripper portion; 
 a second frame supporting a second gripper portion, wherein the second frame is operatively aligned with the first frame; and 
 an actuator connected with one of the frames, wherein the actuator is configured to provide force that causes the gripper portions to engage one another, and wherein the gripper portions are configured to cooperate to support cable when engaged. 
   
     
     
         2 . The system of  claim 1 , further comprising:
 a drive connected with one of the gripper portions.   
     
     
         3 . The system of  claim 1 , wherein one of the gripper portions comprises:
 a first belt;   protrusions extending therefrom; and   a first groove.   
     
     
         4 . The system of  claim 3 , wherein the other gripper portion comprises:
 a second belt;   notches located thereon; and   a second groove.   
     
     
         5 . The system of  claim 1 , wherein the first gripper portion comprises a first gripper portion gear comprising a first central groove located between a first pair of toothed portions. 
     
     
         6 . The system of  claim 5 , wherein the second gripper portion comprises a second gripper portion gear comprising a second central groove located between a second pair of toothed portions. 
     
     
         7 . A system for deploying cable into a well, wherein the system comprises:
 a drive assembly comprising:
 a first frame supporting a first gripper portion; and 
 a second frame supporting a second gripper portion, wherein the second frame is operatively aligned with the first frame, and wherein the gripper portions are configured to cooperate to engage cable; 
   a housing disposed about the drive assembly, wherein the housing has at least two ports allowing lubricant to be circulated therethrough; and   a pair of line wiper assemblies connected with the housing.   
     
     
         8 . The system of  claim 7 , further comprising:
 a drive connected with one of the gripper portions.   
     
     
         9 . The system of  claim 7 , further comprising:
 an actuator connected with one of the frames, wherein the actuator provides a force to selectively engage the gripper portions with one another.   
     
     
         10 . The system of  claim 7 , wherein one of the gripper portions comprises:
 a first belt;   protrusions extending therefrom; and   a first groove.   
     
     
         11 . The system of  claim 10 , wherein the other gripper portion comprises:
 a second belt;   notches located thereon; and   a second groove.   
     
     
         12 . The system of  claim 7 , wherein the first gripper portion comprises a first central groove located between a first pair of toothed portions. 
     
     
         13 . The system of  claim 12 , wherein the second gripper portion comprises a second central groove located between a second pair of toothed portions. 
     
     
         14 . A method for deploying cable into a well, wherein the method comprises:
 placing the cable between gripper portions of a drive assembly, wherein the drive assembly is located in a housing;   closing the housing;   containing well pressure by circulating lubricant into the housing;   engaging the gripper portions; and   providing movement to the gripper portions to deploy the cable into the well.   
     
     
         15 . The method of  claim 14 , wherein engaging the gripper portions comprises extending an actuator connected with one of the gripper portions. 
     
     
         16 . The method of  claim 14 , wherein providing movement to the gripper portions comprises providing power to a drive connected with one of the gripper portions. 
     
     
         17 . The method of  claim 14 , wherein cable is held in a channel formed between the gripper portions when the gripper portions are engaged, and wherein cable moves longitudinally in the space as the gripper portions move.
