This paper examines the corrosion-inhibiting properties of several edible stems at downhole conditions with high concentrations of hydrochloric acid. The objective is to present an alternative variety of corrosion inhibitors that are environmentally friendly and nontoxic.

The authors of this paper find that elongation, reduction in area, and time to failure of Fe17Cr5.5Ni-based alloys were greater than those of Fe13Cr5Ni-based alloys in high-pressure/high-temperature carbon dioxide environments, indicative of better stress corrosion cracking resistance.

S13Cr tubing specimens experienced stress corrosion cracking with phosphate-based completion fluids contaminated with mud and oxygen, whereas formate-based completion fluid is compatible with the tubing.

Monitoring of corrosion in process pipelines has always been of paramount importance in ensuring plant-asset integrity. Similarly, steam traps play an important role in ensuring steam quality and, thus, the integrity of critical assets in the plant.

Saudi Aramco’s papers on new well technology offer glimpses at the challenges of developing its unconventional gas resources.
-
FLITE Material Sciences says that its unique lasering process can be used on just about any type of material to make it either repel or attract water and oil. For an industry that deals with a lot of both, the technology has many potential use cases.
-
The complete paper highlights examples of nonmetallic materials selection and qualification for upstream water-injection and producer and hydrocarbon wells and presents suggestions for future progress.
-
The complete paper presents the results of evaluation of laboratory and demonstration trials of HDPE liner to mitigate premature failures and prolong the run life of production tubing.

Material selection is a first line of defense against corrosion. This article reviews how to recognize pitting and crevice corrosion, as well as how to optimize tubing material selections for marine oil and gas applications based on the material’s PREN value.
