This paper reports on continuous planning and extensive downhole surveying that were vital for a relief well that intersected an underground blowout in Monagas state in northeast Venezuela. This relief well operation in 1989 was the first known application of anchored, oriented, tubing-conveyed perforating (TCP) used to force communication between two wells. The wild well, Tejero 2E (T-2E), was drilled to 17,003 ft total depth (TD) and was producing with a dual completion string from two zones: the lower Jabillos from 16,210 to 16,258 ft measured depth (MD) and the lower Naricual from 15,660 to 15,700 ft MD. It was determined that the upper producing horizon was blowing, but there was some uncertainty as to the status of the lower producing horizon.
