Tortuosity is defined as “something winding or twisted” or “full of twists and turns”.
Well tortuosity is typical of today’s unconventional wells (see Figure 1) and is now acknowledged to result in casing deformation such as collapsed inner diameters (“ovalized casing”). There is also growing awareness among shale operators that excessive tortuosity can predispose the casing to rupture which results in fracturing fluids going into the wrong stages. Rupture occurs in sections which are deformed and therefore more vulnerable to cyclic fracturing pressures, pressure-induced bending, and earth loads. [Read more…]











Knowing what the best practices are in a storeroom or spare parts management process is not enough. The best practices need to implemented, and typically it can’t just be implemented right away. The level of resources, the ability of people to change all prevents the immediate implementation. In addition, not every organization will be at the same starting point or want to go to the same level of maturity. This is where an assessment comes in.
