The kick tolerance is the maximum volume of kick influx that can be safely shut in and circulated out of the well without breaking down the formation at the open-hole weak point. In this article, we will explain the methods, formulas & the most important considerations for kick tolerance calculations. Kick tolerance changes as a …
OBM oil-based mud requires special chemical additives to ensure that the emulsion is extremely stable and can withstand conditions of high temperature and contaminants. Oil mud products must be dispersible in the external oil phase. We believe you might also like this article (Baroid Drilling fluids). The major OBM oil-based mud chemical additives that will …
Dogleg severity is a measure of the amount of change in the inclination, and/or azimuth of a borehole usually expressed in degrees per 100 feet of course length. In the metric system, it is usually expressed in degrees per 30 meters or degrees per 10 meters of course length. All directional drilling wells have changes …

The conductor pipe runs from the seafloor/surface to relatively shallow depths, providing a conduit to allow circulation of drilling fluid and case off unconsolidated formations. It is the first string we use to support well control equipment, typically a drilling diverter. A standard size for the conductor casing pipe is 24″, 26″, or 30″. In …
Planning & calculating a horizontal wellbore differs from planning normal directional drilling wells for oil and gas. In a typical directional wellbore, the target is usually described as a departure at a certain TVD. The target has tolerances in the horizontal plane (North and East). In a horizontal well, the target is commonly described by …
The term bentonite in drilling mud fluids was derived from the location of the first commercial deposit in the United States. In 1897, Knight reported that since 1888 William Taylor of Rock Creek, Wyoming, had been selling a “peculiar clay” found in the Fort Benton shale of Cretaceous age. Knight proposed the name “taylorite.” On …
Drill pipe or Drill collars can be unscrewed downhole by exploding a charge known as a string-shot (prima-cord folded up inside a piece of tubular plastic) inside a selected tool joint connection, just above the stuck pipe point ( check also free point calculation for stuck pipe), this operation can be described as mechanical drilling …

In California, barite was first used in a well being redrilled with cable tools in 1923. According to the report, the density of the mud was raised to 90 lb/ft3 (1.44 g/cm3 ) to control the gas inflow and to stop caving. Here in this article, we will discuss the major knowledge that drilling engineers …
