(04)How we work
How
Geospectra works.
01
Sampled in the field
Bottom-hole, surface, gas, water and soil sampling, with chain of custody from the wellhead.
02
Tested and evaluated
PVT, chromatography, crude assay and specification tests, with every result evaluated before it leaves the lab.
03
Reported to your standard
A signed report, in the format your engineers and regulators work with.
(05)Industries
Every part of the industry.
Operators, gas processors, refiners, power producers, terminals and regulators — tested by the same laboratory and field teams.
Gas & LNG. Gas composition, LNG, LPG and CNG quality, dew point and calorific value.
(06)Locations
Where we work.
Offices and laboratories in Port Harcourt, Benin City, Lagos and Equatorial Guinea — serving projects across West Africa and internationally.
(07)Crude oil fingerprinting
Crude oil fingerprinting.
GC-FID and GC-MSD chromatography identify where a crude came from — used for source identification, contamination tracking, blend differentiation and spill cases.
