Proceedings Papers

Paper presented at the SPE International Symposium on Oilfield Scale, May 26–27, 2004
Paper Number: SPE-87459-MS
..., taking into account cation losses due to scale deposition deep within the reservoir, the requirements for chemical treatments reduces and squeezing becomes the preferred option. From the simulation models, differences between the reservoirs concerned in terms of the contribution aquifer waters make...

... and with respect to other wells and the aquifer), and reaction rate (ranging from no precipitation to equilibrium). In conventional systems with no aquifer, it is demonstrated that maximum scale deposition occurs in the immediate vicinity of the production wellbore, and therefore low produced cation...

Paper presented at the International Symposium on Oilfield Scale, January 30–31, 2001
Paper Number: SPE-68337-MS
... in the oil zone and the water zone is a significant factor in the potential for reservoir souring and subsequent iron sulphide scale generation. Brine mixing occurs to very different extents, depending on the reservoir geometry and on the presence or absence of an aquifer (water zone). When water injection...

..., and suggested that significant scale deposition may occur deep within the reservoir, particularly where a large proportion of injected water sweeps through the aquifer. The current paper seeks to apply that theoretical analysis to the Alba field, on a well-by-well basis, to establish whether diagnostic tests...

... be expected far from the wellbore. Conversely, as the different brine types, which have retained the scaling ions, approach the wellbore, mixing and scale deposition are to be expected. Mixing in the aquifer where brine mobility can be much higher, however, may result in lower than expected ion concentrations...
