Real-Time Data For Artificial Lift Optimization
The necessity for Exploration and Production companies to make smart, on the fly decisions has led to an industry seeking data driven solutions, capable of using real time information to optimize production and enhance artificial lift capabilities. Liberty Lift Solutions, recognized for innovative artificial lift technology improvements, has incorporated real-time downhole data acquisition into a simple, yet robust, instrumentation package. The real time data acquisition system provides our customers with accurate bottom-hole temperature and pressure necessary to maximize well productivity. Our real time data acquisition solution is a perfect addition to Liberty Lift’s innovative artificial lift solutions, including the HyRate® gas lift system.
How it works
DOWNHOLE
The Liberty Lift reservoir monitoring system allows data to be collected and transmitted in real-time using an industry leading robust and accurate piezo or quartz gauge. The gauge is deployed on a custom fit carrier and can be ported to read the tubing, annulus, or both. To enhance system reliability, a custom protector program is designed based on the deviation of the wellbore. LLS gauges can accommodate a wide range of wellbore conditions.
The gauge is powered and deployed into the well with TEC (tubing encapsulated cable). Data transmission with the gauge is established and monitored before, during, and after the install. Up to 8 gauges can be deployed on a single TEC cable. The TEC configuration is chosen based on the wellbore environment.
SURFACE
The TEC exits the wellhead using a special wellhead outlet (WHO) with metal to metal sealing to prevent leaks regardless of pressure
Surface Data Acquisition Cards are used to collect, store and transmit the downhole data. The SDA cards are equipped with Modbus outputs which allows data to be sent via SCADA, cell phone or satellite modem using the Cloud to a computer offsite for further interpretation and analysis. If the required 12 V power supply is not available at the wellsite, solar packages with battery backup can be readily supplied.
