Rosneft Research Institute in Ufa held the annual scientific and technical conference “Oil and Gas Production and Transportation. New Technologies and Solutions”. The event brought together more than 200 industry experts from all over Russia. The Company’s scientists presented innovative technologies and digital solutions to improve the efficiency of field pipelines and wells.
Specialists from the Ufa Institute announced the development of a “virtual flow meter” algorithm for online monitoring of field production. The machine learning-based algorithm will compare well production rates with their potential in real time and create a list of wells whose production can be increased. The technology is planned to be implemented as part of the Digital Field project at Bashneft fields (part of Rosneft). The “virtual flow meter” algorithm is implemented in the RN-VEGA corporate software package and is already used by oil workers when interpreting field data.
The conference participants were presented with a new software product “RN-STIM” for modeling and designing the bottomhole formation zone. The simulator takes into account the characteristics of the rock, chemicals and the features of their interaction. This gives oil workers the opportunity to choose the most effective parameters of the well operation and increase production at the well. The functionality of the software was clearly demonstrated on real production projects during the organized master class.
Another unique development of the institute is the technology of welding bimetallic pipes*. Specialists have found a way to solve the problem of increased hardness and brittleness of the transition layer during one-sided welding of this type of pipes. Instead of the generally accepted technology of making the entire weld with stainless materials, Rosneft scientists proposed using a certain combination of stainless and low-alloy welding materials in combination with the redistribution of the force of the welding arc on the weld. Mechanical tests have shown that this technology increases the strength characteristics of welded joints, while the cost of welding materials is reduced by 3-7 times.
The conference participants showed particular interest in the application of successful practices at production enterprises. With the participation of specialists from the Ufa corporate institute, a technology for treating the bottomhole zone of a well using an acid-hydrocarbon emulsion was introduced. The composition provides an effective impact on the bottomhole zone of wells, due to the dissolution of asphaltene-resin-paraffin deposits and carbonate minerals of the rock. The technology was tested at Rosneft fields – the result was an increase in the growth of well flow rates by 15-20%.
*Bimetallic pipes are pipes consisting of two firmly connected layers of steel of different types
