“…The policy of co-production of sand 9,10 was adopted in Haima reservoir as gravel packed wells were found to have very low productivity index. These wells were completed with PCP from the beginning as these pumps can efficiently handle large volume of solids 11,12 . In new horizontal wells PCP's are being preferentially used these can be installed in the tangent section and facilitates additional pressure drawdown.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractA large brown-field in South Oman showed decline in production despite moderate level of in-fill drilling over the last few years. The field has four major reservoirs distributed across three stratigraphic horizons and contains moderate to highly viscous oil (60 to 400 cp). The reservoirs comprise unconsolidated fluvial, fluvial deltaic and glacial sandstones of Palaeozoic age. The geologically complex field due to large number of faults and fractures has been on production for more than 25 years and has been developed using vertical and horizontal wells during different phases of development. Water-flooding is in operation in two of the major reservoirs for more than 5 years. Well and Reservoir Management in this field poses a formidable challenge due to:• Significant well-stock (more than 450 wells) of different types (vertical, horizontal, multi-lateral) • Problem associated with data acquisition as all the wells are completed with pumps (beam pump, progressive cavity pump and electrical submersible pump) and most of them are completed with some sand-control device • Water-flood management under very adverse mobility conditions in presence of faults and fractures often resulting in premature breakthrough of injected water • Logistical problems associated with large distance between the Well and Reservoir Management team at corporate office and the operational team at field location. The case study presented in this paper describes how a sustained well and reservoir management strategy implemented across the entire value chain starting from the planning to operation stage in this field could not only arrest but literally reverse the field production decline trend using the existing well stock. The paper clearly illustrates that success of reservoir management rests not only on the application of right technology but more on close integration among various disciplines in a cohesive work environment.

“…The manufacturing process of such a rubber screw pump is simple, but in a high-temperature environment, the rubber is easy to age. 5 In the field of oil mining, workers often adopt the mining method of heating the formation to reduce the viscosity of crude oil and artificially create a high-temperature environment to improve the recovery factor. 6 − 10 Therefore, the application of traditional rubber screw pumps is limited, and all-metal screw pumps came into being.…”

The stator and rotor of an all-metal screw pump are made of metal; so the matching method of the all-metal screw pump cannot be like that of the traditional rubber screw pump, and a certain gap must be reserved. If the gap is too small, it will affect the normal operation of the pump. If the gap is too large, the pump leakage will also become larger, affecting the efficiency of the pump. In this paper, the method of numerical simulation is used to optimize the gap of the pump. At the same time, it is found that the optimal gap of the pump is closely related to the viscosity of the fluid transported by the pump, and different viscosity fluids have different optimal speeds. The speed and clearance of the pump are optimized through numerical simulation to ensure high pump efficiency while taking into account energy saving and avoid the waste caused by excessively high speed. Finally, the relevant research results of numerical simulation are verified through experiments, and it is found that the experimental results are in good agreement with the simulation results, which also proves the accuracy of the numerical simulation results.

“…Hascakir et al (2008) investigates the improvement effect of electrical heating on heavy oil development, and evaluates the influence of electrical heating parameters on wellbore temperature and viscosity of producing fluid. Although electric submersible pump (Bortolin et al, 1992) and progressing cavity pump (Dunn et al, 1995) are no longer new technologies in heavy oil exploitation, there are less systematic reports on the application of integrated well pump, insulated tubing and heating sucker rod techniques in deepwater heavy oil testing. Pilot test shows that gel treatment is capable of stabilizing oil rate and controlling water production in heavy oil reservoirs of China offshore oilfield.…”

Heavy oil reservoirs have became a key and difficult point as exploration and development of oil and gas goes deeper. Since deepwater heavy oil reservoirs are characterized by adverse fluid property and poor flowability resulting from low seawater temperature, conventional well test usually fails to gain expected crude sample and real formation data, leading to some problems for subsequent development. In view of two difficult issues during the deepwater heavy oil reservoirs test -flow assurance concern and decision-making difficulty in testing system, application of appropriate test technologies and techniques are of great importance.Prior to the offshore test, an integrated approach to modeling and designing operating conditions was described. The feasibility of available technical solutions in relation to enhancing the low wellhead temperature conditions was discussed based on the wellbore temperature and pressure features derived from the analytical modeling, and a test technique (integrated progressing cavity pump (PCP), heating sucker rod and insulated tubing) applicable to deepwater heavy oil reservoir was recommended. Then, drilling-stem test (DST) was carried out to an exploration well with two oil layers and one gas layer which is located in southwest of Congo sea with the recommended test technique.Simulation results demonstrate that the advantages of the compound technology -electric heating, PCP and insulated tubing are far greater than using insulated tubing or heating sucker rod alone. Compound technology decreases the frictional pressure loss of the producing fluid due to its capability of maintaining high and uniform wellbore temperature. Interactive tubing conveyed perforating (TCP) and DST was conducted with a testing program of thrice flow well and twice shut-in well. Insulated tubing assembly was employed from progressing cavity pump stator to the wellbore and the setting depth of the heated sucker rod was down to about 10m above the pump. Productivity information, representative crude samples and pressure/temperature information of the testing zone were obtained successfully.The simulation technology and pilot test proved the feasibility of insulated tubing and electric heating PCP in deepwater heavy oil testing, providing technical guidance for further appraisal and development of deepwater heavy oil fields.
