Tailoring of wormlike micelles as hydrodynamic drag reducers for gravel-pack in oil field operations
Publikováno v:
Journal of Petroleum Science and Engineering. 146:142-148
This paper describes a systematic investigation to verify the potential of wormlike micelles (WLMs) as additives to improve gravel-pack operations. This is an important step of the completion operations, in which a sand core along of an oil well is c

Drilling processes are viable only if drilling fluid is used. Drilling fluids are responsible for a number of operations, including cooling the system, carrying drill cuttings to surface, transmitting pressure and signals throughout the well and othe

Recent deepwater discoveries in CO2-laden presalt regions have posed new drilling and cementing challenges associated with salt and CO2. Salt can react and gel cement slurry prematurely, resulting in pumping and displacement issues. Further, creeping

Under a conventional oil well drilling task, the pore pressure (minimum limit) and the fracture pressure (maximum limit) define mud density range and pressure operational window. During oil well drilling, several disturbances affect bottom hole press

Abstract The development of Brazilian Pre-Salt reserves will require a large numbers of wells to be drilled. Once the operational associated costs are extremely high, operational practices that can save drilling time are very welcome. The salt layers

Abstract The completion of long horizontal intervals is a challenge faced by Petrobras since the discovery of heavy oil offshore fields in the 80's. The gravel-pack completion is a well know technique applied successfully in hundreds of offshore well
