In-situ high pressure PH measurement and biofilm sampling device

A method for testing properties of a pressurized multiphase fluid sample containing at least hydrocarbons and water. The pressurized multiphase fluid sample is placed into a first pressurized chamber of a testing device. The water is separated from the hydrocarbons. At least part of the separated wa...

Beschreibung
Zusammenfassung:	A method for testing properties of a pressurized multiphase fluid sample containing at least hydrocarbons and water. The pressurized multiphase fluid sample is placed into a first pressurized chamber of a testing device. The water is separated from the hydrocarbons. At least part of the separated water is flowed through a first outlet in the first pressurized chamber and into a second pressurized chamber. The second pressurized chamber is optionally isolated from the first pressurized chamber. A pH level of the separated water is tested in the second pressurized chamber. Microbial activity and growth is tested for in the pressurized multiphase fluid in the first pressurized chamber. A pressure of the pressurized multiphase fluid is substantially maintained throughout the placing, separating, flowing, isolating, and testing steps.
