Frequently asked questions
What grade of barite does OJEX supply in Nigeria?
We supply API 13A specification barite at 4.10–4.20 specific gravity, screened for residue and moisture, with a certificate of analysis per batch. Packaging options are 50 kg sacks, 1.0 MT and 1.5 MT big bags, or bulk vessel/truck delivery to Port Harcourt, Warri, Onne and Onshore rig locations.
Can you supply calcium bromide and clear completion brines to a required density?
Yes. We supply calcium bromide, calcium chloride, sodium chloride and sodium bromide as solids or pre-blended clear brine at your target density (up to 14.2 ppg with CaBr₂), filtered to 2 NTU where the completion programme requires it. Provide the density, crystallisation temperature limit and volume, and we return a quote with the blend sheet.
What is HEC liquid used for?
HEC (hydroxyethyl cellulose) is a non-damaging viscosifier used in gravel-pack carrier fluids, sand-control completions and workover pills. It builds viscosity in brines without leaving a permanent filter cake, so it can be broken and cleaned up after the job. We stock both HEC liquid and HEC powder.
Do your chemicals ship with certificates of analysis?
Every batch ships with a manufacturer certificate of analysis and, where applicable, an SDS in GHS format. On request we arrange third-party sampling and independent lab verification before release.
What are the minimum order quantities and lead times?
Stocked drilling chemicals such as barite, bentonite, CaCO₃ and mica typically ship within 24–72 hours from our Port Harcourt supply base. Imported specialty production chemicals run 2–4 weeks depending on volume and packaging. There is no fixed minimum for stocked lines; specialty blends are quoted per drum, IBC or ISO tank.
Can you deliver directly to rig site?
Yes. We deliver to rig site, jetty, or client warehouse across Rivers, Delta, Bayelsa, Akwa Ibom and Lagos, including offshore transfer via supply vessel where the operator provides the logistics window.
