Exploration

Reliable level measurement and control of trip and mud tanks/silos are achieved by using the robust TDR type Levelflex. The guided radar runs an electromagnetic pulse along a cable or rod and is unaffected by build-up, dust or changing dielectric constants. Two Levelflex instruments can be installed close together for redundant measurement. The Promass F mass flow meter is involved in the online mixing and blending of expensive mud (WBM and OBM) as well as in custody transfer measurement at the point of transfer to supply ships and mud tanks on site. The online measurement of density and viscosity keeps the mud parameters constant. The world's first digital pH measurement with Memosens allows for the precalibration of pH sensors in the mud logger cabin.

To ensure excellent cement quality for the batch, the Promass Coriolis mass flow meter monitors the flow rate online as well as the pumped cement density. The fast action Levelflex controls the level in the very small mixing pit on the truck. Every drop of a chemical additive is quantified with Promass A, available at a diameter of 1 mm.

Online blending of frac jell is implemented with Promass for mass flow, density and online viscosity measurement. Cerabar S and Deltabar S pressure transmitters allow process operation of up to 1,000 bar/15,000 psi. These smart pressure transmitters have an integrated thermocouple and store all adjustments and settings in an integrated memory chip. Additionally, the last 25 hours of process operation are recorded.  All data from all the fracing units involved in the process are visualized and recorded in a paperless Memograph recorder. This unit is also able to monitor setpoints, calculations and act as an independent PLC and communication unit.

Many activities in oil field exploration and production involve open and closed tanks for water, mud, fuel, etc. For all these applications, the level device that fits best must be selected providing simple operation, re-liability and most of all, cost effective level measurement. A solution is always available from the large portfolio of Endress+Hauser, including Levelflex guided radar, Liquicap capacitive, Prosonic ultrasonic, Micropilot radar, Deltabar DP-level and many other alternatives. Most appreciated by well servicing operators are Levelflex and Prosonic for their easy commissioning and reliable operation regardless of whether their operations are at the arctic circle or in the hot and humid tropics.
