Downhole corrosion of sucker-rod thread joints can be effectively controlled using an inhibited thread lubricant. This standard materials requirement provides a method of selecting effective sucker-rod thread lubricants for use by oilfield production operators.
This standard was originally prepared in 1974 by NACE Task Group T-1 D-11 on Selecting Inhibitors for Use as Sucker Rod Thread Lubricants, in response to a request from the American Petroleum Institute (APl). It was reaffirmed in 1988 and again in 1995 (with editorial changes) by Unit Committee T-1 Don Corrosion Monitoring and Control of Corrosion Environments in Petroleum Production Operations. It is issued by NACE International under the auspices of Group Committee
T-1 on Corrosion Control in Petroleum Production.
1.1 Proper selection and use of corrosion inhibitors provides extended protection of sucker-rod threads and box cavities against the effects of corrosive well fluids that may move in and out of these box cavities, and protects the threads from galling.1
1.2 This standard defines requirements for inhibited lubricants and suggests types of tests that may be used to select such materials.
1.3 This standard is not a test method. Suggested procedures for testing inhibitors in simulated environments in which they are to be used are described in Section 3.
The tests may be run in simulated sweet, sour, aerated, or combination environments with simulated well fluids or actual field fluids. . Historical Document 1995
