Determination of Gas-Water Boundary in Gas Reservoir Using Dim Spot Technique—an example of Kekeya E2k gas reservoir

Abstract

Abstract: The seismic and geologic proof is concluded in this article, which can explain the dim spot existed at the deep Kekeya's E₂k gas reservoir, from studying the acoustic impedance and the surface reflection coefficient of Kekeya gas-bearing carbonate rock. On the basis of correct layer defined, and by means of color display in the computer, the dim spot is successfully identified and the border of gas and water as well as area of gas containing is finally confirmed.

Key words: Kekeya, gas reservoir, dim spot, reflection coefficient, acoustic impedance, amplitude, gas-water contact
