Anyone knows how I can put into the wellbore a Liner?

I need know this for make a calculus of weight, I mean, I want to know if I must sum the weight of the liner with the weight of the drillpipe. So i don´t know how I can put into the wellbore a Liner?

Thanks friends.

To set a liner into the wellbore take count on this: Weight of liner (pounds per feet), total length of liner, TD (MD) well, mud weight, total lenght of pipe to reach the liner point, is the well vertical, deviate or horizontal (to calculate the weight hung and supported by the walls of the borehole), you must know how the liner will set (how the setting tool will release and set the liner, compression-tension-rotation?)....
;
Once u have this data, calculate the total weight of the liner, the total weight of the pipe.... obtain the total weight in the mud of each one: (BF*(Wt liner)) and (BF* Wt pipe).
This numbers are very important to set the liner and release the setting tool once the liner is in place.
If the well is highly deviate or horizontal u must consider the borehole inclination and obtain the real weight of each component in tension (remember, if the well is deviate or horizontal, two X and Y dimension represent the coordinates of the weight). In drilling operations such force are call Tension and friction forces.

Another point to be consider is how the setting tool will release the liner, common tools works with compression and rotation to release the tools (but ensure u know how this setting tool works and if has a secundary mechanism to release the liner in case of emergency).....

If you need a detailed operational procedure to run and set a liner, please e-mail me: oileruis@gmail.com
