PEREZ, JULIO et al. DEVELOPMENT AND IMPLEMENTATION OF A METHODOLOGY FOR INTEGRITY EVALUATION IN WELLS WITH ELECTRIC HEATING. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.154, pp.101-111. ISSN 0012-7353.

The integrity of actives in the petroleum industry is highly important for safety reasons, compliance of environmental regulations, reduction of maintenance cost and prevention of unexpected production shut-down. The objective of this article is to establish a methodology to evaluate the integrity of wells that use electric heating as enhanced oil recovery method, in such a way that can be established if the wells in study are under appropriate mechanic - metallurgic conditions to implement this method. The proposed methodology can be divided in the following stages: planning, evaluation approaches and analysis of results. The planning is directed toward the elaboration of a working plan that will be carried out in the system with the purpose of gathering historical information of inspection, maintenance and rate of corrosion calculations; to evaluate the current conditions an evaluation womb is used in order that determines the applicability of the method of electric heating in the wells in function of the parameters that define the ambient of the system and the coating material. After analyzing the results it is determined if the well is capable for the application of the recovery method. Finally the article shows two examples of application of the methodology to the wells of the HOCOL`s Hocha field from Huila - Colombia. The major contribution of this article is the development of a methodology that allows to evaluate different structural and operation parameters to give a diagnosis of the well before designing and implementing the electric heating as recovery method, avoiding this way economic losses.
