Godchaux Well No. 1, Vermilion Parish, Louisiana: completion and testing. Final report
The Godchaux Well No. 1 was originally drilled too a total depth of 16,000 feet in January, 1981 by C and K Petroleum, Inc. and was temporarily abandoned. The well was re-entered by Eaton on 6 August 1981 in an effort to clean out the original open hole below the 7-5/8 inch liner and test a section of the Planulina sand at a depth ranging from 15,584 to 15,692 feet. The reservoir pressure was estimated to be 14,480 psi, and the temperature of the formation water was expected to be 298/sup 0/F. The water salinity was predicted to be 70,000 ppM. The well was expected to produce up to 20,000 BWPD, was a gas content of 44 SCF per barrel. An optional test of a zone from 14,905 to 15,006 feet was also proposed in the detailed completion prognosis, which preceded the attempted test. In the process of drilling the cement plug set by the original operators, the drill string became side-tracked from the original hole. While drilling at 14,510 feet a severe loss of circulation of drilling fluid occurred through a hole in the intermediate casing. The reduction in hydrostatic head resulting from lost circulation caused the open hole to close around and stick the drill string. Efforts to repair the intermediate casing and return to normal operations were estimated to be prohibitively expensive in view of the expected poor probability of success; accordingly, the decision to plug and abandon was carried out on September 12, 1981.
