1. Please state the client and field /
installation name.
2a. Please state the nature of the scaling
problem e.g. scale blocking pipeline, scale dropping out in the
separator.
2b. If scale has already formed, is a sample available
for analysis?
2c. Has a radioactive count been carried
out on the sample (if so, please state reading obtained)?
3. Is the scaling problem known to be a
carbonate or sulphate-scaling problem?
4. Is a full brine analysis including pH, total dissolved
solids (TDS), bicarbonate and sulphate levels available?
5. What is the temperature profile of the produced
fluids from production to processing i.e.
a) Reservoir
b) Bottom hole
c) Tubing head
d) Topside process
6. What are the system pressures i.e.
a) Bottom hole
b) Tubing head
c) Topside Process
7. What are typical production rates (please
state both oil and water production)
8. Is a scale inhibitor currently being used?
If yes,
9. What is the incumbent product?
10. What is the incumbent dose rate (L/day)?
11. Where is the incumbent injected?
12. Is there a dedicated injection line for the
scale inhibitor?
13. Are samples of the separated crude oil available?
(1-5 L would be helpful for partitioning studies)
14. Is H2S present in the crude oil?
15. Do you require ecotox and biodegradation
information on our scale inhibitors?
