Ingevity introduces new line of biodegradable solvents for oilfield applications


US-based Ingevity has introduced a new line of biodegradable solvents known as EnvaSolv to be used in oilfield applications.

EnvaSolv products are terpene-based solvents that dissolve wax and asphaltene build-up in wellbore, surface and pipeline systems and prevent downtime.

The new product line has similar performance characteristics to d-limonene-based solvents and benzene, toluene, ethylbenzene, as well as xylene (BTEX) solvents.

However, the line serves as an environmentally friendly option with stable pricing when compared to d-limonene-based solvents as it is derived from pine chemicals and is easier and safer to handle compared to BTEX solvents.

"Historically, the oilfield industry has been forced to choose between using environmentally friendly products or products with more stable pricing."

Ingevity oilfield business development and innovation global director Todd Schroeder said: “Historically, the oilfield industry has been forced to choose between using environmentally friendly products or products with more stable pricing.

“We are excited to offer a product line that offers both of these characteristics.”

The company’s oilfield technologies team exhibited EnvaMul emulsifiers, EnvaDym dimers and EnvaCor corrosion inhibitor intermediates; EnvaBreak de-foamers and anti-foamers; and EnvaSolv dissolvers at the Society of Petroleum Engineers Annual Technical Conference and Exhibition held from 26-28 September at the Dubai World Trade Centre.

Ingevity’s specialty chemicals and carbon materials are used in various demanding applications, as well as in oil exploration and production.

The company operates from 25 locations worldwide.
