... select the best approach and tool to achieve expected cementing results. This allows densities to be defined as well as slurry and spacer volumes, displacement rates, and the recommended minimum SBP necessary for safe execution, thus helping minimize losses and avoid kicks. For the case discussed, casing...

...-hydrophobic interaction. Two different methodologies were used to evaluate the fiber's ability to enhance the chemical wash and spacer capabilities to clean and demulsificate the nonaqueous mud fluids. The laboratory tests were performed with cementing preflush fluids with and without the fibers. Results...

..., they will compromise project objectives. To avoid excessive operating costs and to remove near-wellbore damage, a quick and efficient removal of SBM or OBM with properly-designed clean-up fluids, such as microemulsion fluids, is required. Properly designed microemulsion spacer fluid formulations can be used...

... held apart with spacers. A vacuum is drawn in-between the two pipes, providing superior insulation. Outside the corrugated pipes a PE sheath is extruded and two tensile armor layers, separated by anti-wear tape layers are applied. The pipe is sealed with an external PE sheath for mechanical protection...
