An important factor in the viability of mature oilfields projects is the application of alternative technology that helps to optimize the process; operating time is perhaps the most important factor to take into account when referring to a project for this type of field. Technology such as that provided by echometer with its Total Well Management (TWM) software makes it possible to apply well tests in a fast and efficient way, since for this process it is not necessary to carry out Workover jobs, thus avoiding production losses due to well intervention, this is because it is equipment that is installed on the surface and is connected to the wellhead. This equipment determines the fluid column and consequently the bottom hole pressure (BHP), as well as an approximation of the reservoir pressure, formation damage (skin damage) and permeability. The application of technological alternatives is a successful way of knowing reservoir behavior.
