Method of estimating the region of damage due to collapse in the wall of a borehole during the drilling operation

The present invention relates to a method of estimating the region of damage due to collapse in the wall of a well during the drilling operation, normally using drilling fluid, where said well can, for example, be intended either for the injection or else for the production of a gas or oil reservoir...

More Information
Summary:The present invention relates to a method of estimating the region of damage due to collapse in the wall of a well during the drilling operation, normally using drilling fluid, where said well can, for example, be intended either for the injection or else for the production of a gas or oil reservoir. Other uses can be found in mining and in civil engineering work. This method is characterized by a set of analytical steps that allow establishing, for example, optimal drilling parameters so as to allow the fastest possible drilling speed that is also safe enough to allow is charging the collapse material without jamming the drilling tool. This method likewise allows assessing both the width and depth of damage in the wall of the well.
