... IV tests were performed using core material from the fields for catastrophic sanding risk evaluation over well lifecycle, and examination of sanding under steady state flow conditions with varying fluid type. Laboratory test results and simulation data were then used to determine safe operating...

...-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...

... chloride or 3 to 5% potassium chloride. It is well known that the addition of salt to cement slurry impairs the slurry properties, especially free fluid and compressive strength, two important parameters to determine a successful cement evaluation. Several laboratory tests were performed until the ideal...

... in this paper was developed and tested by technological cooperation between the Petrobras Research Center (CENPES) and laboratories at PUC-Rio. In this article, the results of laboratory tests carried out with full-scale prototypes of these systems are described in good details. armor laboratory test...
