Since early 1980, BP has been developing the conceptual design of a Single-Well Oil Production System or SWOPS. This paper outlines the concept and discusses the design and the operational criteria that have been applied in this early work. It further examines some of the innovative areas of technology that have been included in this new approach and outlines the work of the detail design phase, which has just started.

This paper reviews key production process for crude palm oil and highlights factors that highly influence the production of crude palm oil. This paper proposes a generic conceptual model for crude palm production process considering these factors. The conceptual model could be modified to consider other factors not included in this paper. The future research would be to construct a simulation model based on the conceptual model proposed in this paper and analyse the effect of these factors on the performance of crude palm oil production system.

It aimed to dynamic change of oilfield productivity, maked sure that the progressing cavity pump is working in a highly efficient region. It combined variable frequency conversion technology and dynamic liquid level height control technology, the closed-loop control of oil production system with progressing cavity pump is made up of rotation-speed and torsion sensor, stepless motor, frequency converter, PLC and progressing cavity pump. The result show that the system can control the pump submergence depth by adjusting the rotation-speed and torsion of polish rod, and make sure the pump working in a highly efficient region finally. This system also can increase recovery efficiency and pump service life.

Abstract The underwater hydraulic connector is one of the most important components of an underwater oil production system. The equipment is mainly used to transport oil, chemical reagents, and other high-pressure fluids. We developed a novel underwater hydraulic multi-way quick connector system (MQCS) that is able to realize simultaneous, rapid, and precise plugging and unplugging of 10 underwater pipelines. It can be widely used for connection between subsea oil production equipment. The MQCS consists of a fixed plate assembly that is fixed to the oil production equipment and a free plate assembly that is connected to the pipelines on the drilling platform. This study describes the structure and working principle of the MQCS in detail. In addition, the process of the elastic collet clamping the mandrel was studied. Based on the finite element analysis software Abaqus, we investigated how the key geometric parameters of the elastic collet influence the axial force that needs to be provided by the underwater robot. A prototype was built based on the simulation results. To verify the performance of MQCS, a high-pressure chamber test was conducted. The results show that MQCS can accurately connect 10 high-pressure lines (about 69 MPa) in a high-pressure chamber and there is no pressure drop for 3 h after docking.
