Pipe inspection systems and methods

Coiled tubing or a portion thereof having a first part spaced-apart from a second part, the coiled tubing having a first outer diamter at the first part and a second outer diameter at the second part, the first outer diameter different from the second outer diameter, and outer diameter of the coiled tubing continuously diminishing or increasing from the first part to the second part, in one particular aspect thus varying over its entire length; and methods for using and methods and apparatuses for making such coiled tubing.

Variable OD coiled tubing strings

A method for taking into account the effects of complex conveyance method model technique results in real time in a wellbore operation, the method including, in certain aspects, calculating with a conveyance method model technique a series of data points based on wellbore data (actual and/or predicted), modeling the relationship between the series of data points and the wellbore data using a simple mathematical model technique to develop a model for predicting a wellbore operations parameter, and using the model to predict a wellbore operations parameter; and, in one aspect, a procedure for drilling a wellbore in the earth using such a method to predict, among other things, weight on bit, torque on bit and stretch of a conveyance system (coiled tubing, wireline, drill pipe string) used to move the bit in a wellbore.

Method for wellbore operations using calculated wellbore parameters in real time

The present invention, in certain embodiments, discloses an apparatus for determining characteristics of coiled tubing that is run in and out of a bore, e.g. a wellbore, for calculating fatigue life of the coiled tubing, the apparatus having a reel structure for said coiled tubing including a reel on which said coiled tubing is wound and a frame supporting the reel for rotation, an injector structure for running the coiled tubing from the reel structure into said bore and for withdrawing said coiled tubing from the bore, sensor apparatus for continuously monitoring sensing and recording rotation of said coiled tubing and for measuring amount of said rotation, said sensor apparatus including apparatus for receiving and transmitting data relating to said characteristics of the coiled tubing, and a computer apparatus for receiving data from said sensor apparatus and processing said data to determine fatigue life of said coiled tubing.

System and method for measuring and controlling rotation of coiled tubing

The present invention, in certain embodiments, discloses a method for moving a conduit, e.g. a cable, in certain wellbore operations, the method, in certain aspects, including a method for introducing cable into a wellbore, the method including providing wellbore cable through a pressure control device to a capstan drive system above an earth wellbore, and pulling the wellbore cable through the pressure control device with the capstan drive system.

Wellbore cable system

Tractor system

A tractor system for moving an item through a wellbore has been invented with a central mandrel interconnected with the item, first setting means about the central mandrel for selectively and releasably anchoring the system in a wellbore, the central mandrel having a top, and a bottom, and a first power thread therein, the first setting means having a first follower pin for engaging the first power thread to power the first setting means to set the first setting means against an inner wall of the bore. In one aspect, the tractor system is for moving the item through the bore at a speed of at least 10 feet per minute. In one aspect, the tractor system has second setting means on the central mandrel for selectively and releasably anchoring the system in the bore, the second setting means spaced apart from the first setting means, and the central mandrel having a second power thread therein and a second retract thread therein, the second retract thread in communication with the second power thread, and the second setting means having a second follower pin for engaging the second power thread to power the second setting means to set the second setting means against the inner wall of the bore.

Bore tractor system

A new wellbore tractor system has been invented which, in one aspect has at least two slip units for alternately and releasably anchoring the system within a wellbore or within a tubular member and at least two movement units for moving an item in a wellbore, such as, but not limited to cable, tubing, casing, a tubular string or coiled tubing.

Wellbore tractor and method of moving an item through a wellbore

A method and apparatus for the installation of cable into a reel of coiled tubing includes a cable injector. The cable injector comprises a capstan drive within a pressure housing. In a preferred embodiment, the capstan comprises a drive wheel that is enclosed within the pressure housing and the pressure housing is made up of a pair of seal plates or flanges with a seal ring between them. A drive shaft penetrates one of the flanges. This arrangement minimizes the size of a rotating seal in the pressure housing.
