Formation Water Transport

ROCH is a private company dedicated to the exploration and exploitation of hydrocarbons. As part of their production plans, it was necessary to produce and treat formation water which will then be injected through injection wells for secondary recovery. The purpose of secondary recovery is to maintain reservoir pressure and facilitate the displacement of hydrocarbons to the HC producing well.

The specific challenge was not only to find a pipe material that could support the composition of the fluid, but also to solve the following situations:

– Both the workforce and the heavy equipment, in Santa Cruz (Argentina), are very expensive and represent a very significant portion of the total cost of putting a line of production to work.

– The line had to cross a field belonging to the businessman Benetton, in which sheep are raised to produce wool that is used for his clothes business. Benetton did not allow trenches to remain open during the night (for fear that the animals could fall inside). This situtation, forced to work on sections, opening the trench, installing the pipeline and refilling the trench on the same day.

The pipe options that were handled were steel, HDPE and PE-X.
