Oil & Gas

Monitoring natural water bodies surrounding oil and gas drilling activities like hydraulic fracturing is a key issue in environmental monitoring and regulatory compliance.

Hydrolab multiparameter sondes can measure a variety of parameters pertaining to energy operations including conductivity and specific conductance, total dissolved solids, salinity, pH & Redox potential (ORP), chloride, dissolved oxygen, and turbidity. Both OTT and Hydrolab sensors can be setup with telemetry options to trigger alarm messages if certain parameter thresholds are breached.

OTT groundwater level sensors can measure current water levels around oil & gas operations and are involved in remediation monitoring, typically using conductivity as a surrogate measurement.
