Peculiarities of planning and running pulse test without well shutdown

Information on the structure of the deposit and pressure communication between wells is required to control development and plan geological and engineering operations. Pressure transient test using the pulse-code is traditionally used to record the generated pressure pulse in shutdown observation wells, which leads to reduced rates of oil production. Pulse-code test method has not been applied in operational wells in the world practice. The article considers the main problems arising in the process of pulse-code testing on the operational well stock, as well as provides possible solutions to the potential problems occurring in the process of the study and factors that interfere with the successful conduct of the work.
