Transcripción del resumen del autor: Water or gas coning can adversely affect oil production in oil reservoirs. In oil reservoirs, a large oilrate can cause upward coning of water or downward coning of gas into the well perforations. Once gas or water is produced, the oilrate decreases and the cost of water and/or gas handling is increased. There is a criticalrate below which the cone remains stable and does not break through to the wellbore. In the present work, a simple-to-use approach, which is easier than existing approaches, less complicated with fewer calculations, is formulated to arrive at an appropriate estimation of criticaloilrate for bottomwaterconing in anisotropic and homogeneousformations with the well completed from the top of the formation. This simple-to-use correlation can be of immense practical value for petroleum engineers to have a quick check on estimating the criticaloilrate for wide range of conditions without the necessity of any field test trials. In particular, petroleum engineers would find the proposed approach to be user friendly involving transparent calculations with no complex expressions for their calculations.
