The key operating device of the Intelligent Well Management System (IWMS) is the Intelligent Well Controller (IWC), which is an electronic device, with a new technology to obtain control of the well based on surface and downhole dynamometric registers, the result of associated parameters and calculations, and the behavior of the electric motor.The purpose of this paper is to share our experience on the IWMS implementation and its contribution to: reduce the frequency of well interventions, accelerate the detection of well failures and decrease associated Downtime (DT), a quicker response detection at the waterflood affected wells, faster production optimization with new wells, save on energy demand, redesign the field operators' daily routine, define well selection criteria, and relocate current controllers. Taking advantage of the benefits of IWMS, we feel we are getting closer to excellence in the hydrocarbon producing field operations.

Conventional technology on downhole sensors allowed the development of standard equipment capable to work in wells up to 150°C and some cases 175°C permanently. If higher temperature is required, existing technology offers sensors that can operate up to 260°C without electronics downhole. Such sensors use separate encased multicore cables. But cost and deployment are limitations making instrumentation not feasible for high WC wells. Thus, confining these products to specific application such SAGD. Using Defense and Aerospace technology, an affordable downhole sensor was developed for Panamerican Energy to withstand 225°C permanently and have excursions on 250°C. This sensor does not require an additional cable. Communication is achieved by over imposing the digital signal in the existing power cable, reducing cost and installation complexity. This paper shows the development of the product, specifications, and lab tests, field examples that helped to maximize production and protect the artificial lift equipment.
