Many of these results were used in the planning of subsequent well site activities like perforations and have been proven accurate in resulting flow tests. When combined with other data like 3D seismic the RVS data...

... Abstract The traditional chemical cross-linking method is based on the formation of covalent bonds between molecules to connect three-dimensional networks to enhance the strength of hydrogels. Although this method can significantly improve the mechanical properties, it also has many problems...

... on the mechanical properties of the rock. Acoustic strength and scratch tests were conducted to evaluate rock mechanical parameters such as unconfined compressive strength. Further inhibition potential was evaluated by conducting linear swell and capillary suction timer tests. The contact angle was measured...

..., the B sand was found to have the highest MBE risk due to its lower geomechanical strength, the D sand was found to have a significant yet lesser risk, and the A sand was found to have negligible risk. MBE risk is greater for patterns with horizontal production laterals without sand control...

... by weight of cement (BWOC) were mixed and cured with various additives for 24 hours at 76.7 °C with 24.13 MPa. Uniaxial compressive strength (UCS) tests were performed which suggested the inclusion of ANF's increases the UCS when compared to cement samples without ANF's. Although, high concentrations...

... brittleness are considered good candidates for hydraulic fracturing. However, many researchers argue that this viewpoint is not reasonable, because rock brittleness is not an indicator of rock strength and the current brittleness indices are based on elastic modulus or mineralogy. Brittle rock just has...

...) and the critical shear strength (maximum area-specific force). Two Class G cement compositions were tested: a 15.8 ppg neat cement (Class G neat) and a 14.2 ppg gelled cement (Class G with 7% bentonite). The testing was done at temperature and pressure regimes designed to conform to environments typical...

.... For example, a 10.60 ppg slurry with cement-perlite ratio of 1:2 (by volume), 15.5 gal/sk of mix water and 4% bentonite will yield a compressive strength of 520 psi after 24 hours under a curing pressure of 3000 psi ( Nelson and Guillot, 2008 ). In addition to density reduction and slurry yield increase...
