Abstract
Various general-purpose software packages can be used to optimise the design of scale inhibitor squeeze treatments. However, the versatility and cost of these codes typically makes them cumbersome and expensive to use for optimising routine squeeze treatments. Conventional treatments should be modelled using purpose designed squeeze simulators that minimise data entry and facilitate quick extraction of results. However, misapplication of even a fit-for-purpose simulator can lead to incorrect treatment design. This problem is compounded by the fact that squeeze strategies are always being developed and refined, and the software must be developed to keep pace with these changes in technology if it is going to be applied correctly.
To deal with these twin issues, this paper will first describe how a squeeze simulator should be correctly applied, and what information may and may not validly be extracted. Potential pitfalls will be highlighted, as well as techniques for optimising the model set-up to ensure that the maximum amount of relevant data is utilised. Experience gained from use of the SQUEEZE V software for modelling core floods, single and multi-layer radial well models will be discussed, and the rationale for making certain decisions when building a model will be highlighted. Secondly, new features being introduced into this code are discussed, together with the impact these may have. The new facilities include two-phase flow, with the potential for component transport in the oleic phase, and full crossflow within the formation in addition to the well. Finally, the paper will present planned future developments that should improve the applicability and scope of the code, without increasing the difficulty of use unduly.
