METHOD OF CONSTRUCTING AN ISOBAR MAP FOR OIL AND GAS CONDENSATE FIELDS Russian patent published in 2020 - IPC E21B47/06 E21B49/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry and can be used in construction of isobars map for developed oil and gas condensate deposits (OGCD). Proposed method comprises using data of wells registered in ICS OGCD data base (DB). Simultaneously, the information-control system (ICS OGCD) controls the means of the well gas wells telemetering system monitoring the wellhead pressure P_w, wellhead temperature T_w, gas flow Q_i, and writes them to its DB. Based on results of these measurements, ICS OGCD checks each operated well for absence of emergency situations in its operation. In case of emergency situation detection in well ICS OGCD excludes results of made measurements for construction of isobars map on this date and uses average daily design value of reservoir pressure, which was determined at this well immediately before detection of emergency situation. Simultaneously ICS OGCD issues appropriate message to service personnel for immediate measures to eliminate emergency situation.

EFFECT: high accuracy of real-time construction of an isobar map in automatic mode using an information-control system (ICS OGCD) for any given date at the request of maintenance personnel.
