WebGas coning occurs when the pressure drop at the perforations exceeds the pressure head resulting from the difference in densities between the overlying gas and the oil times the oil column height allowing gas to be pulled downward into the perforations. From: Well Integrity for Workovers and Recompletions, 2024. WebNumerous methods have been presented to avoid gas breakthrough because of coning. These approaches include: keeping oil production rates beneath a certain value, forming a gas-blocking region nearby the well by inserting crosslinking gels or creating

WebVarious critical-rate correlations for horizontal wells are listed in Table 8-7. [4], [12] [15] In a reservoir with bottom water or top gas, rising water and downward movement of the gas cap can be controlled to obtain the best possible sweep of the reservoir. As shown in Figure 8-1, this is also called water cresting. WebConing is a term used to describe the mechanism underlying the upward movement of water and/or the down movement of gas into the perforations of a producing well. Coning can seriously impact the well productivity and influence the degree of depletion and the overall recovery efficiency of the oil reservoirs. The specific problems of water and ...
