Question 1

Who supplies oilfield production chemicals to PDO and OQ contractors in Oman?

Accepted Answer

Global Chemicals LLC is JSRS-certified for supply to Petroleum Development Oman (PDO), OQ, OPAL and their approved contractors. Our production chemicals range covers corrosion inhibitors, scale inhibitors, H2S scavengers, demulsifiers and reverse demulsifiers, oxygen scavengers, biocides, defoamers, THT gas odorant, methanol and MEG for hydrate control, and drilling additives (bentonite, barite, CMC). Deliveries run on scheduled interior routes to Marmul, Nimr, Qarn Alam and Fahud with hazmat-trained drivers, and every batch carries CoA and GHS SDS.

Question 2

How are demulsifiers selected and dosed for crude oil treatment?

Accepted Answer

Demulsifier selection is bottle-test driven: candidate chemistries are screened against a fresh wellhead emulsion sample for water drop-out speed, interface quality, and dehydrated-crude BS&W. Typical continuous injection is 10–100 ppm upstream of the FWKO or desalter, adjusted seasonally as water cut changes. For produced-water clean-up the mirror problem — oil dispersed in water — takes a reverse demulsifier at 2–20 ppm ahead of flotation or hydrocyclones to meet oil-in-water discharge or reinjection specs. We supply both chemistries and support field bottle testing.

Question 3

What is THT and how is natural gas odorized in Oman and the GCC?

Accepted Answer

THT (tetrahydrothiophene) is the sulphur odorant injected into odourless natural gas so leaks are detectable by smell — the safety requirement for city-gas grids, industrial distribution, and CNG networks. Typical injection is 10–25 mg/m³ of gas, dosed by proportional injection pumps at the city-gate or distribution station. THT is favoured over mercaptan blends where oxidation stability and low soil-adsorption matter, holding its odour intensity further down the network. We supply THT in sealed drums with Class 3 handling documentation and injection-rate guidance.

Question 4

Which scale and corrosion inhibitors work for high-salinity produced water?

Accepted Answer

Oman's produced waters commonly run high in chloride, calcium and sulphate, driving both CaCO3/CaSO4 scaling and accelerated steel corrosion. Phosphonate scale inhibitors (dosed 3–10 ppm continuous) handle carbonate and sulphate scale up to moderate supersaturation; for harsher brines, polymer-blend inhibitors are squeezed or continuously injected. Corrosion control pairs film-forming imidazoline inhibitors (10–50 ppm continuous, or batch between pig runs) with oxygen scavengers on any system open to air ingress. Send your water analysis and our technical team will specify the programme and doses.
