A Method And A System For Determining Height Of Fluid In An Annulus Of An Oil Well

Abstract: The present invention discloses a method and a system for determining the height of the fluid in an annulus of an oil well. The method involves receiving invariant values for one or more first parameters associated with characteristics of the oil well, and receiving first and second values for one or more second parameters defining the oil well's characteristics at distinct time intervals after the well is shut in. By analyzing variations between these values, the method defines changes in the characteristics of the oil well. A height of the fluid in the annulus is then determined at a third time interval using a predetermined relationship based on these values. This method enables accurate assessment and determination of the fluid level, enhancing decision-making for oil well management and optimization. Figure 3 is the representative figure.
