It is impossible to control and adjust an oil and gas field development without determining the flow intervals of production wells. For that it is preferable to get production profiles by using the downhole flowmeter. There are, however, some main restrictions for wide-spread application of them on the offshore of Vietnam as follows:

  • –

    The flowmeter spinner velocity cannot indicate correctly in the open hole wells having a ununiform diameter.

  • –

    It is unable to carry out in the case when the tubing shoe is lower than top formation on 300 - 500m.

In this paper, the authors present a summary of temperature profile method to determine the flowing and intaking intervals of wells drilled in basement of the White Tiger Field on Vietnam offshore.

For last 2 years more than 30 wells were surveyed by this method in the above mentioned conditions.

This paper presents the theory and practic of well temperature profile surveys, the concrete examples of data interpretation using the software "Oiltest".
