Corrosion in an oil well can happen for several reasons, including:
Exposure to corrosive substances
Oil wells often contain substances that are corrosive, such as hydrogen sulfide, carbon dioxide, and other acidic gases, which can cause corrosion of the well casing and production tubing. These substances can react with the metal in the well, causing corrosion.

The Problem
In the oil and gas industry, the development and operation of an oilfield usually is affected by undesired microbial growth. The development and operation of a well is usually affected by unwanted microbial growth. The microbial contamination may occur when well is being drilled, when the well is being stimulated or when the well is in production phase.
Scale problem in oil production is a big issue. We have found an interesting article published at Petrowiki website. We transcribe below some excerpts of such article, related to scale formation and use of inhibitors.
FLOCGREEN™ is a new green and environmentally friendly aloe based product for use as flocculant in the treatment of the wastewater generated by hydraulic fracturing when performed at unconventional oil and gas drilling operations.
