Mejoramiento de un programa informático para la selección de nuevas tecnologías de control de arena de tipo mecánico en campos operados por Ecopetrol S.A.

In Colombian oil fields it occurs that, due to the sanding, there is a corrosion, erosion and plugging of the equipment and the surface and subsoil pipes, thus increasing the frequency of intervention work in the hydrocarbon producing wells. Given the above, the need to improve the sand control module arose. This one is composed by two tools from the already existing General Manual of Wells Completion (MGCP), in order to recommend four new sand control technologies for their usage in reservoirs with both highly non-uniform sandstones and fine grain size ranges. The improvements introduced to this module allowed that within the first tool (theoretical matrix for the studied oilfields) these four new technologies were recommended for their usage in 22 of the 24 fields studied by previous authors, belonging to five Colombian basins. In addition, the second tool was updated by introducing these four new mechanic technologies and including a second selection parameter (average grain size) for recommending the use of an either new or conventional mechanic tool of sand control based on both the previously mentioned parameter and the already existing coefficient of uniformity.
