La  necesidad  de  obtener  agua  en  cantidades  económicamente  explotables ha originado la perforación de aproximadamente 140 000 pozos. En un futuro próximo muchos de estos pozos requerirán de mantenimiento y rehabilitación y, en otros casos, al terminar su vida útil, serán clausurados o simplemente abandonados.

In a near future many of these wells will require maintenance and rehabilitation and, in other cases, at the end of their useful life, will be closed or simply abandoned.
