... out between the acid and overflush brine (with and without SI), reservoir fluids (i.e. crude oil and synthetic formation brine) and completion brine. The impact of the proposed stimulation package was visually assessed based on the rate of fluid separation and quality of the interface. Spent Acid...

... The prevalence of horizontal and deviated well completions in which lubricious fluids are required makes the development of a suitable lubricant for completion brines an important achievement. This paper describes the development of a new brine lubricant that is able to: reduce the coefficient...

.... Polymer with significantly lower decomposition temperature can be used as a barrier to protect the film. For this type of completion, the polymer film barrier is removed when the wellbore is converted to aqueous completion brine. This allows the operator to choose the timing of the removal of the barrier...

... Abstract An API-sponsored work group has developed a robust field and laboratory method for determining the pH of oilfield completion brine. This method is precise, gives reliable pH values, is free from interferences, and can be easily implemented across industry. It is anticipated...

... Abstract Wellbore cleanups are an integral part of the effort to reduce formation damage during completion operations. One operation that can significantly impact the cost of the well completion is the displacement from mud to completion brine. SBM (synthetic-based mud) cleanups pose unique...

... Abstract The use of high density brines in well completions and/or recompletions poses potential problems for initial well production. Emulsions may be formed when the crude and completion brine are commingled under high shear at points such as the perforations, well-head, chokes and valves...

... Abstract An unexpected source of potential formation damage can be generated when controlled debris perforating systems are detonated in clear completion brines. This paper presents the results of a systematic laboratory study of this potential damage, previously unreported in the published...

... Abstract Laboratory studies were conducted to determine the completion techniques for two wells in the Gulf of Mexico having well angle of 35 to 45 degrees, completion interval of about 400 ft, bottomhole temperature of 222°F and requiring a completion brine with density up to 17.0 lbm/gal...

... Abstract The use of high viscosity gravel pack carrier fluids in gravel packing operations has been an accepted industry practice for more than 20 years. However, experimental results obtained using an acrylic gravel pack simulator indicated completion brines were superior gravel carrier fluids...
