Effectiveness study on the system for gas gathering, treatment and transportations from gas production company
Journal Title: Технологический аудит и резервы производства - Year 2018, Vol 3, Issue 1
Abstract
<p><em>Results of the analysis of gathering and processing and transmission systems efficiency are presented in work for Opishnia, Kotelva and Zakhidna-Berezivska gas-condensate fields of the UkrGasVydobuvannya, Joint-Stock Company (</em><em>Kyiv, Ukraine)</em><em>. The main complications of gas-gathering system at the final stage of fields’ development are revealed and some meanings for estimation of their negative impact on volume of production are proposed.</em></p><p><em>At the first stage of the research, field measurements were made of the operating modes of the system in summer and winter. It has been experimentally established that during the winter period of operation the process of gas separation on separation equipment is performed more qualitatively than in summer operation. This is due to the effect of low temperatures on the process of precipitation of the liquid phase from natural gas.</em></p><p><em>The main idea of work lays in introduction of continuous monitoring of gas-gathering system operating with identification of changes of the thermobaric modes. Such changes can signal high probability of liquid accumulations that creates additional hydraulic resistance.</em></p><p><em>Results of monitoring of P–T profile, changes in dew points and natural gas composition allow to carry out complex analysis with acceptable accuracy to estimate a possibility of liquid accumulation in certain points of the piping system. This excludes need of confirmation of their existence by means of the instrument metering and additional human resources and reduces time needed for problem identification. </em></p><p><em>Such approach will be rather interesting also to the large international companies as reserves of natural gas are constantly decline, and recovery of residual reserves from the depleted fields in gas drive mechanism is the attractive purpose for the gas productions companies. Furthermore, application of easy ways of cleaning based on the analysis of hydraulic efficiency of pipelines allows to reduce significantly both timing, and material resources.</em></p>
