PROFESSIONAL EXPERIENCE

3/2014 – 12/2014

Shale Water Research Center, LLC Chemical Engineer Houston, TX

Resolved the Long Time Challenges of Production Flow Assurance from Friction Reducer (FR) Additives (Devon

Energy's Project)

Challenges:

o FRs, e.g., polyacrylamide (PAM), form aggregates that decrease the oil transportation efficiency and impair

the production

My Contribution/Achievements:

o Identified that FR polymer bridged with multivalent Fe3+ and Ca2+ ions is the root cause for the loss of oil

transportation efficiencies (through dissolution of field aggregates)

o Successfully reproduced FR aggregates using PAM and fracturing water in lab condition

o Developed the method of eliminating field FR aggregates using citric acid through chelation of metal ions;

field production was exponentially boosted after citric acid treatment

o Successfully prevented aggregate formation in field by applying cationic/ nonionic instead of anionic FRs

o Prepared and issued several detailed reports which had generated vast interest from shale oil companies in

Texas, e.g., Apache Corporation, Devon Energy

Barite (BaSO4) Scale Inhibition during Long Term Storage of Fracturing Water (Apache Corporation's Project)

Challenges:

o Barite scale negatively impacts the transportation efficiency and threatens safety due to accumulation of

Naturally Occurring Radioactive Materials (NORM).

My Contribution:

o Investigated efficiencies of varying scale inhibitors in novel laser test to screen the most effective one
