It includes an extended slip with enhanced design (coupled with a new greasing system), a 2.5 million lbs landing carrier and a pipe with a thick walled high strength...

... and strength of the geopolymer/SBM blends were measured under downhole conditions. Strength testing results showed that geopolymer cement lost only 30% of its strength when blended with 10% SBM, while a neat Portland slurry lost 70% strength. Geopolymer/SBM blends containing up to 40% SBM were found to have...

... are believed to occur in tension rather than compression, which has led to increased focus on cement tensile strength. However, most technical literature related to cement tensile strength refers to testing at ambient temperature and pressure, which does not represent actual downhole conditions. In this study...

... Comparative studies of perforation stability with a standard TWC tester (Thick Wall Cylinder tester) and a new compact TPS tester (Triaxial Perforation Stability tester) were performed using sandstone cores with UCS (Unconfined Compressive Rock Strength) ranging from 500 to 7000 psi.

... design premise is that the product in the application must endure the applied mechanical forces without failure. However, this is not the behavior of proppants in most applications. Rather, proppants experience mechanical force that typically exceeds their strength causing them to fail in the fracture...

.... Wellbore stability analysis is conducted to validate calculated stress and rock properties against drilling observations. Uniaxial compressive rock strength (UCS) is an integral part of geomechanics studies involving mechanical earth modeling. Absence of direct core measurement brings uncertainty...
