Abstract
Currently, oil and gas companies around the world are paying close attention to the intellectualization of assets. This process is resource intensive, requiring increased requirements for the selection of implementation sites depending on the tasks assigned. In physical terms, the greatest effect of the integrated approach is realized when saving capital investments at the stage of choosing the strategy for developing new large fields. Considering that most of the existing fields are in the late stages of operation against the backdrop of high descending volatility in the cost of oil, the relevance of the positive results of the introduction of the concept of "Intelligent Field" on the underlying assets is increasing.
In this paper, the results of the intellectualization of a mature asset (a field in development since the late 1960s) are given as features: the depth of the oil-bearing horizon is more than 4.5 km, the high gas factor is more than 250 m3 / ton, the focal development system, restriction of the control capabilities of the pressure maintenance system, the proximity of the nature protection zone.
The presented characteristics of the field lead to a number of risks that are realized in the manifestation of the chain of complications, such as: uneven drop in reservoir pressure, the appearance of local zones of degassing, the breakthrough of injected water, an increase in the frequency of the change of submersible electric pump equipment, the fall of HDAS in BHZ and segments of the oil collector and pipes etc. Thus, the increase in the number of measures to prevent and eliminate associated complications leads to an increase in operating costs.
In the materials of the work the key areas of the concept "Intelligent Field" are highlighted, the complex implementation of which allows qualitatively improving the reliability of calculations and evaluating the effectiveness of the current system of development and productivity of the technological chain. These results clearly show the wide possibilities of using the implemented systems and the potential for achieving quantitative results, such as the reduction in daily fund downtime and monthly losses in oil production, improving the quality of the planned operational regime of the wells, targeted increase in the degree of influence on the reservoir system, increasing employee productivity in the analysis and forecasting of production and injection levels. Synergy effects allows to minimize the risk of additional transaction costs without compromising technological safety.
The presented work makes a certain contribution not only to strengthening the methodological knowledge of the oil industry community, but also to developing a set of examples with successful results of approbation of the approaches to intellectualization of the asset, useful as "benchmarking" in the oil and gas industry.
