Almost 400,000 petroleum wells have been drilled in Alberta to the end of 2012. Of those, approximately 150,000 have abandoned and of these, approximately 50,000 have yet to be certified as reclaimed. Prior to abandonment, wells may be suspended, which is also an important related challenge that may have financial implications for operating companies through the Licensee Liability Rating (LLR). In this period of low energy prices, more wells are being suspended, increasing financial strains on many producers and technology solutions and innovative solutions are required.
Multi Phase Pumping (MPP) is a multi-phase pumping system engineered by the Globotics Industries group to enhance and optimize the productivity of on-shore oil wells. The system is particularly suited to remote or isolated wells or in any case those with unsuitable eruptive pressure due to their position and the features of the pipeline they are connected to.
Major advantages of the technology are:
- Zero cost impact
- Increase oil & gas production for the oil & gas company
- Increased revenue
- Zero environmental impact
- Opportunities for further improvements as the technology matures
MPP is used to recover significant quantities of fluid from wells that would otherwise be unusable, both by a thrust action boosting the flow and by reducing the wellhead pressure and thus improving the normal productivity of the well. MPP is a modular, skid-mounted system that can be designed for installation in almost all functional on-shore extraction conditions, provided that the “physical-geological” features of the well ensure its effectiveness.
Following a scientifically validated and widely consolidated sizing process, the preliminary study of the well service parameters (feasibility study) qualifies the functional features of the most suitable pumping system to use in order to exploit the well in the best possible way. The wellhead pressure, the bottom hole pressure (BHP), the process fluid features (Oil, water and gas), the GVR and the nature of the oil itself are just some of the parameters analyzed in order to define the optimal operating range of the system, which is indispensable for ensuring full production efficiency according to the fluid-dynamic progress of the well over time.
The pumps are configured according to the flow rate and delivery pressure features required to ensure the optimal flow of the multiphase fluid into the pipeline, in single units or multiple configurations in series or in parallel. The pumps are supported by a sophisticated control system that controls the pump operation based on the feedback describing the well’s functional parameter trends, thus continuously adapting the suction methods to the optimal operating conditions of the fluid extraction process. The overall modularity and flexibility of the system represent an important factor for application: having completed its functional purposes for one or more wells, the MMP can rapidly be re-adapted, modifying the configuration of the processing equipment, adding or removing any new equipment, making it immediately available for installation in other wells.
In addition to illustrating the effectiveness of the MMP system in the above-described conditions, we will discuss the possibility to integrate the MMP with submersible pumps in series, also to exploit wells with no pressure or those with a prevailing percentage of gases over liquids.
