Delivering high quality, onsite fluids analysis with Expro's ELITE composition

Delivering high quality, onsite fluids analysis with Expro’s ELITE composition

Customer challenges

Expro’s client needed to obtain reservoir compositional and contaminant data as part of a high profile E&A campaign in Southern Europe
Good quality samples were a key objective of the campaign, and the operator required assurance that the samples were captured correctly and there were no nonconformities
With no PVT laboratory in the area, samples would need to be exported for analysis, and their quality would not be known until they had reached the lab
Decisions on whether to proceed with next steps of the operation required input from sample analysis
If samples were not representative, no further opportunities would be available to re-sample

Expro Excellence

Expro’s proposed solution delivered on the rig data, providing confidence in sample quality, as well as initial composition and contaminant data to confirm the value of the reservoir fluids
TurboPVT transfers were used to validate samples during transfer from openhole tool to transport bottle, recording transfer progress and providing phase volumes, mud contamination levels, and pressurized density measurements
ELITE Composition delivered C36+ hydrocarbon composition of the reservoir fluids, including BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes), CO₂, and N₂, as well as GOR and stock tank liquid density
Further onsite analysis was conducted on the samples, including mercury and hydrogen sulfide in the hydrocarbons, and ionic composition of two water samples by MultiIon analyzer

Value to client

All samples were transferred, ensuring their integrity by restoring to reservoir conditions and maintaining single phase throughout
Operator was able to confirm samples contained target fluids, and no further sampling runs were required
Initial analysis of the samples confirmed the quality of the hydrocarbon discovery, and allowed the client to calibrate logs and improve the accuracy of their dynamic reservoir data
Client is able to move forward with the next project phase, commence reservoir modeling much sooner than had samples been sent to a conventional
lab, and bring forward decisionmaking by more than two months
Knowing contaminant levels enables earlier procurement of materials for upcoming projects in the area
