Probe arrays for monitoring wellbore fluid composition and methods of using the same

A method comprising:

• (a) measuring one or more fluid properties of a wellbore fluid in a container containing the wellbore fluid using a probe, array comprising a flotation device and an acquisition module positioned below the flotation device wherein the acquisition module remains submerged in the wellbore fluid and includes probes for measuring dissolved oxygen, pH, turbidity, or conductivity;
• (b) maintaining the probe array adjacent to a surface of the wellbore fluid and determining a change in the one or more fluid properties of the wellbore fluid over a time interval from the measured fluid properties;
• and
• (c) performing a remedial action to change the one or more fluid properties.

A probe array system for monitoring one or more properties of a wellbore fluid comprising:

• a buoyant flotation device configured to maintain the probe at the surface of the wellbore fluid in a pit or tank being monitored wherein the probe array consists of multiple probes for measuring or monitoring the wellbore fluid;
• an acquisition module secured to the flotation device such that the acquisition module is positioned below the surface of the wellbore fluid and is capable of functioning in the measurement or monitoring of a physical property of the wellbore fluid;
• a protective cage surrounding the flotation device functioning to provide impact protection to the flotation device and acquisition module while allowing wellbore fluid into the flotation device and acquisition module;
• a transmitter configured to receive data acquired from the acquisition module and transmit the data to a computer system configured to receive the data from the transmitter and configured to perform the steps of:
• processing the data to determine one or more wellbore fluid properties, and
• displaying the one or more wellbore fluid properties;
• and
• one or more cables capable of transferring data from the acquisition module to the computer system.
