CLEVELAND - Rezul -- Delphin Logger Automates Data Collection & Pump Shutdown

CAS DataLoggers provided the data acquisition solution for MTS Solutions (https://www.mts-stim.com/), an oil field service company headquartered in Bakersfield, California. MTS has been providing well stimulation services in California for over 30 years, maximizing production for clients using both traditional and green products.

After sourcing Delphin data acquisition systems, Kevin developed a program using ProfiSignal software for MTS's oil well stimulation services and operations. His program auto-transmits job data over WiFi in real-time to well owners, documents the entire job, remotely shuts off pumps if necessary, and calculates productivity. In this way, Delphin performs Data Acquisition, Monitoring, and Automation—all in a single system.

Multi-Parameter Monitoring in Real-Time

In late 2016, MTS Solutions sourced three Delphin Expert Loggers from CAS DataLoggers. These Model 100 loggers have a 4GB internal memory to store data along with a WiFi interface. MTS also opted for the Klicks software option enabling automation capability along with runtime monitoring.

In this application, the Expert Loggers are installed on different service trucks which travel to job sites, each monitoring multiple measurement values including Pump Pressure, Flow, Volume (in gallons), Runtime, and Productivity.

To collect the data, users have connected the loggers' universal analog inputs (mV mA, TC, RTD) with different sensor types such as 4-20mA pressure sensors and New-Flow™ flow meters. The Expert Loggers have been set up to sample data from each connected sensor once per second.

Wireless Data Transfer

Data collection is performed automatically over Wireless Ethernet. MTS uses WiFi hotspots for wireless connectivity and fast data transfer so that well Engineers, Field Operators and MTS management can all view data in real-time, using their PCs or mobile devices. The Expert Logger provides the data every second which provides a clear picture of operations on well stimulation services.

Electronic Documentation

Operators start and end their job with a button press that creates a datafile in CSV format containing an In/Out timestamp along with location name, well name, and operator name. During the shift, the ProfiSignal program automatically documents all operator actions taken, including pumping time and chemical switch-outs. This datafile is then exported as an ASCII2 file and timestamped.

Alarm Capability

The program also has multiple two-tier alarms set. Four alarms provide over-watch on pump pressure and wellhead pressure. England explains, "We have a preset maximum value set for well pressure, given to us by the customer and then set in the program on our side by the Operator. Operators also have a digital alarm set with their rig PLCs."
