Like any mature industry that has been around for decades; each with their tried and true technologies; the ESP industry also has its standard technologies which have been applied in varying degrees over the years. The level of success to which these technologies have reached has clearly been seen in the immense growth seen in the ESP industry. This is not to say that there have not been improvements to stage design (e.g. radial vs. mixed flow vs. axial, vane geometries), motor and motor seal design (E.g. induction motor technology and SAGD designs) and deployment methods, but these improvements have been slight deviations from what had been accepted as "standard".
Historically, ESP stages have been Type 1 or Type 4 Ni-resist and despite the changes in designs as mentioned, the stage materials have essentially remained the same. A change in the stage material and processing paradigm has drastically widened the historic application window.
This paper will elaborate on how a new stage technology combined with Permanent Magnet Motor technology deliver a unique solution providing a wider range of efficient operations (ROR), greater gas and sand handling capability without specific gas handling equipment and a shorter overall package.
The technology will be described, specifically how it is radically different than the case stages typically used today and the results of field trials demonstrating this wider range and its ability to handle produced sand.
