aASTM D2887 | Boiling Range Distribution of Petroleum Fractions by Gas Chromatography

bASTM D93 | Flash Point by Pensky-Martens Closed Cup Tester

Elevance HFS® are patent-protected unsaturated

ester solvents produced from plant oil feedstocks that

improve solvency and boosts performance in various

oil field applications such as cement spacer and

wellbore cleanout spacer.

Typical Elevance HFS® Application Areas

• Oil field applications targeting replacement of terpenes, BTEX and other polar organic solvents

• Cement spacer and wellbore cleanout spacer

Why Choose Elevance HFS®?

• Improved Environment, Health and Safety (EHS) profile over d-Limonene and dipentene

• VOC exempt in the US

• Free of Benzene, Toluene, Ethylbenzene, Xylene (BTEX)

• Readily biodegradable and derived from plant oils

• Stable pricing and reliable sourcing compared to d-Limonene

Elevance HFS® Solvents Form Stable Water-borne Microemulsions

Dynamic light scattering of an Elevance HFS® microemulsion (0.5 gpt) revealed small uniform solvent droplets with an average particle diameter of 119 nm and a polydispersity index of 0.122 (Figure 1). Small particle sizes can improve reservoir capillary delivery, demulsification and solvency. Figure 1 confirms the water white appearance of a typical Elevance HFS® microemulsion. The Elevance logo on the back of the bottle is clearly visible, consistent with submicron particles of solvent on average dispersed in water.

Application — Cement Spacer and Wellbore Cleanout Spacer

Elevance HFS® Flushes and Cleans Oil-Based Drilling Muds Better.

Elevance HFS® containing mud cleaner removed more oil-based drilling mud better than d-Limonene. Pre-weighed metal foil test strips were submerged in oil-based drilling mud for 5 seconds, then weighed again. The mud coated foil was submerged in 4 ml cleaning fluid (10% vol Elevance HFS® microemulsion in water) while connected to an overhead stirrer for 2 minutes. The microemulsion in this study was prepared by mixing 24% HFS, 60% BIO-SOFT® 91–6, and 16% Dowanol™ DPM. The foil was air dried for 2 minutes, then weighed. The procedure was performed at room temperature.

LEVERAGE THE SUPERIOR CLEANING PERFORMANCE OF ELEVANCE HFS® TO BUILD YOUR BUSINESS.

A microemulsion containing Elevance HFS® 1012 and one containing d-Limonene was designed for a cement spacer application tested for oil-based mud removal. The mud was coated onto a viscometer and was run at different RPMs to compare cleaning performance. The Elevance HFS® 1012 microemulsion cleaned 2X better than the d-Limonene microemulsion at various speeds.

Figure 3. Elevance HFS® microemulsion outperforms d-Limonene microemulsion in cement spacer applications.
