... also be taken into consideration while planning for ERD wells. We can take the example of Wytch Farm extended reach drilling by British Petroleum which has created a new milestone by drilling and completion of an ERD well with an horizontal displacement of 35,196 ft. the Wytch Farm oil field had three...

... Abstract The stacked sands of the South Tapti field have presented completion challenges from field start-up in 1997 to the present-day. A large part of these challenges have been caused by reactive shales interbedding the sand bodies. This has had a persistent influence on the sandface...

... of these innovative lightweight slurry systems in terms of better well completion, reduced cost, improved productivity and less safety/environmental hazards in cementing across highly depleted zones and weaker formations. The details of the development, case studies of successful field implementation alongwith...

... Abstract This paper will discuss a Monobore one trip cement through completion system. The system was designed to add artificial lift capabilities and improve safety to short life monobore wells. The disposable well bore concept is gaining popularity in regions worldwide. This paper will also...

... Abstract The Alba field in the central North Sea is an unconsolidated sandstone reservoir with an average permeability of around three darcies. Maximising productivity and extending completion life has been an evolving process throughout the life of this field. Recent practice is to drill...

... across the openhole H1 reservoir. Following the well testing results on the appraisal well, a full qualitative analysis of the well type suitable for these reservoirs was completed. The analysis looked in depth at other sand exclusion methods available, including traditional openhole horizontal gravel...

... Abstract Ideally, a reservoir drill-in fluid (RDF) possessing both an oil external phase for drilling and a water external phase for completion would provide the ideal solution for drilling and completing a well. Through the manipulation of surfactant chemistry, a novel reversible invert...
