Ways to Decrease Production Costs for Sucker-rod Pumping
Mainly due to its long history, sucker-rod pumping is a very popular means of artificial lift all over the world, roughly two-thirds of the producing oil wells are on this type of lift. To maximize profits from these wells in the ever-changing economic situation with rising costs of electric power, installation designs must ensure optimum conditions. In the paper, basic considerations on ensuri...
متن کاملStrength Sucker Rod Steel in High SO42- Environment
9 In some sour reservoirs and tertiary oil recovery blocks, SO42in solution can cause the corrosion 10 and corrosion fatigue of the sucker rods. In this paper, the corrosion behaviors of super-strength 11 sucker rod FG20 (16Mn2SiCrMoVTiA) steel in the well fluid are investigated by electrochemical 12 measurements, and electron probe micro-analyzer (EPMA) analysis. The results show that FG20 ste...
متن کاملLiquid Organic Fertilizers for Sustainable Agriculture: Nutrient Uptake of Organic versus Mineral Fertilizers in Citrus Trees
The main objective of this study was to compare the performance of two liquid organic fertilizers, an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. The source of the fertilizer (mineral or organic) had significant effect in the nutritional status of the organic and conventionally managed mandarins. Nutrient uptake, vegetative growth, carbohydrate synthesis and...
متن کاملRobust Adaptive Control of a Sucker-Rod Pumping System of Oil Wells
Several studies have shown that the satisfactory oil well operations with sucker-rod pumps is attributed to the techniques and methods which are able to control the performance of the well. However, the presence of uncertainties in the sucker-rod dynamical models or parameter variations may jeopardize the desired performance of the control system and the rod pump system productivity. These para...
متن کاملModelling and Identification of a Sucker-Rod Pumping System of Oil Wells
The aim of this paper is present an application of modelling and identification techniques in a sucker-rod pump system. The results show a dynamic system model and its relationship with the real process variables in this kind of artificial lift oil method. The model obtained from experiments with real data is representative and can be used for applications, such as for instance, a control syste...
