Electric Submersible Pump

With the rapid development of the offshore oil industry, electric submersible pumps have become more and more important. They are the main pumping equipment in oil well production and have huge advantages in terms of displacement and production costs. Due to the complex structure of the electric submersible pump, the bad working environment will cause failures. The failure of tubing string leakage is a common failure in oilfields; tubing string leakage of the electric submersible pump will reduce oil production. In order to reduce the economic loss of oil well production. This paper uses PCA and Mahalanobis distance to make the tubing Fault diagnosis of leakage. The feasibility of the algorithm is verified through experiments. The result shows that it can diagnose the failure time of pipe string leakage in advance and hence help us to reduce the maintenance cost of offshore oilfields.

This paper presents an application of a stabilizing model predictive control (IHMPC) strategy with the underlying guarantee of feasibility to an oil production well system with Electric Submersible Pump (ESP) installation. The proposed controller is compared with a conventional finite-horizon MPC which provides some unfeasible solutions in the presence of an unmeasured disturbance, due to the typical conflict among the ESP-lifted oil well system constraints. The results show IHMPC as a viable choice to improve ESP-lifted well production since it can incorporate the desired requirements and provides stabilizing control actions.

Abstract The advantage of cable deployed electric submersible pump (CDESP) systems are beginning to be understood and realized as experience has been gained with the deployment and retrieval of these systems. Cable deployed ESP systems have at times been touted as a temporary system for failed conventional ESP systems. Long-term successes have demonstrated the value of permanently installed CDESP systems, which provide the benefit of reduced production deferral, less costly change-out, and reduced HSE risk. The decision to change from conventional ESP to a rigless CDESP system is not necessarily a simple conclusion. The decision must consider technical, economic, and operational considerations to gain the full benefit from the technology. The learnings developed over multiple deployments and retrievals will benefit decision makers in the evaluation of the technology use. The technology application presented in the paper sheds the light on a journey to develop and bring alternative ESP deployment from concept to reality, overcoming technical and operational challenges. The current CDESP requires a rig to initially construct the permanent completion to accept the rigless CDESP system. Production rates requirements determine the ESP size, and in turn the tubing and wellhead size. Pressure control equipment is installed on top of the Christmas tree. Rigless installation and retrieval of the CDESP is performed on an elevated tower with the wellhead in place. The tower design has been improved to allow the production flowline to remain in place. A minimum of two well barriers, with one barrier well kill fluid, are in place at all times. A key learning of the killed well CDESP system is the need to understand the potential changes to the reservoir after sustained production in planning the replacement of a failed ESP. Kill fluid losses can be higher than expected with restorative well cleanup and production. Actual deployment or retrieval time can be improved with successive change-outs. Long-term operational robustness of the CDESP is proven with a system continuing to operate after 5 years of cumulative operations. This paper shares the lessons learned from an early technology adopter with multiple deployment and retrievals in various well environments including highly fractured reservoirs and high hydrogen sulfide wells.

<em>In thisresearch the application of permanent magnet motor and asynchronous motor in X Well was evaluated. The permanent magnet motor and asynchronous motor used in this research are PM51 – NFO 150 FLT @50hz and</em> <em>AM51 – NFO 150 FLT @50hz, respectively. Several parameters are compared such energy losses, energy consumption, motor heating, and production rate. Based on the data analysis, there are some advantages by using permanent magnet motor which can help to improve efficiency and consume less energy, therefore can give more profit within the same period of production. These advantages consist of durability for motor, consume less electricity energy to maintain</em> <em>the operation of ESP string, give bigger production rate, and longer expected life time than an asynchronous motor. The implementation of permanent magnet motor is recommended in oil well that has high fluctuation in production flow rate, since the setting flow rate of the motor is adjustable.</em> <em>This advantage can be useful to give longer lifetime and hence to reduce the pump replacement program</em>

ESP (Electric Submersible Pump) pumps are one of many methods of artificial lift used in the world. By optimizing the operation of the pump, a balance is achieved between the inflow of fluid from the reservoir and the equipment, which prolongs the run life of the equipment and increases production. Remote monitoring of the ESP system and its parameters in real time enables the evaluation of the pump's performance trend, as well as the prediction of potential equipment failure, which leaves room to take measures that would prevent well workover. The level of technology, in addition to monitoring, also offers remote and automatic control of the ESP system. Intelligent control stations of the ESP system use mathematical algorithms to draw and analyze the pump performance curve and, based on them, automatically change their operating parameters so that they are the most optimal. Another great advantage of this system is that it allows virtual measurement of well production via an algorithm based on IPR (Inflow Performance Relationship) analysis.

Electric Submersible Pump

When the pressure of an oil well is not too large to do Natural Flow, Artificial Lift is one of the methods that can be used to replace it, artificial lift usually using ESP (Electric Submersible Pump). ESP oil pump in petroleum is equipped with VSD (Variable Speed Drive) component to adjust motor speed as softstarter and oil rate regulator and as pump motor protection. For ESP construction with a motor tandem system installed on wells with different characteristics and depths that are different from ESP single motors. However, submersible pumps are augmented by increasing the number of pump stages according to the depth of the well by coupling, submersible electric motors can be mechanically coupled and electrically on a spindle between upper motor and center motor.
