Effect of Phase Redistribution on Pressure Build-Up Curves
Abstract/Contents
- Abstract
- The interpretation of pressure build-up data by conventional means is sometimes difficult due to deviations from theoretical behavior. Anamolous pressure build-up behavior in the form of humps (an initial rise followed by a decline in pressure) has been noted. The principal causes of teh departure can be attributed to well bore storage, well bore damage or stimulation. In some instances the method of completion and fluid redistribution within the borehole also affect pressure behavior.In this paper the results of a laboratory investigation on phase redistribution in a well bore are presented. The effect of the velocity of the bubble rise, total volume of gas in the system, and the location of the point of gas entry have been investigated. Experimental observations indicated that, the pressure build-up due to bubble rise is directly proportional to the total volume of bubbles in the well bore and inversely proportional to the initial top gas volume above the liquid column. Results also indicate that, the time to reach the hump is directly proportional to the upward velocity of the bubbles and to the depth of the pay zone from the surface.
