The Permian Basin is an oil-and-gas-producing area located in West Texas and the adjoining area of southeastern New Mexico. The Permian Basin covers an area approximately 250 miles wide and 300 miles long and is composed of more than 7,000 fields (best represented in Railroad Commission of Texas production figures as districts 7C, 08, and 8A) in West Texas.1 The greater Permian Basin accounts for nearly 40 percent of all oil production in the United States and nearly 15 percent of its natural gas production.

Texas, has increased due to high demand. It is estimated that approximately 30 billion barrels of oil and 75 trillion cubic feet of natural gas of been produced from Permian wells since the 1920s. Due to global demand for oil and gas, Permian production is once again growing and is estimated to continue to break production records by 2027.
During oil and gas production, API 5CT L80 production tubing is commonly used. Due to the exposure to the production of oil, gas and produced water, and other chemicals the internal surface of the tubing experiences wear and corrosion.
Lately, L80 tubing failures due to various corrosion mechanisms were observed. This paper presents two case studies of L80 corrosion failures and associated corrosion mechanism(s) via lab failure analysis.

Martensitic Stainless Steel (SMSS) is widely used for downhole production tubing and liners in the Oil & Gas industry. Optimization of the tubular material chemistry, cleanliness and manufacturing route has delivered useful performance in H2S-containing environments (specifically SSC and stress corrosion cracking [SCC])3 resistance4,5,6. Some tubular accessories and most completion equipment require sizes not readily delivered by tubular product form. In these instances, bar stock material is a pragmatic choice.

Although organic corrosion inhibitors have been widely applied in the energy industry, many details regarding their protection mechanism remain unknown. For example, a corrosion inhibitor adsorbs on the clean steel/aqueous solution interface, driven by electrostatic interaction. With the corrosion product
layer formed, how would the inhibitor adsorption interact with the corrosion product nucleation and precipitation? What is the effect of pre-corrosion in inhibitor testing?

This paper reviews the corrosion management for a critical sour gas pipeline operated by Saudi Aramco. The 38-inch diameter pipeline transports untreated sour gas from Crude Processing Facility (CPF) to downstream Gas Plant and spans a total distance of 145 km. To prevent internal corrosion inside the pipeline, the wet sour gas is dehydrated using Tri-Ethylene Glycol (TEG) unit.
