... production. However, operators lack a proactive method to determine acid stimulation candidates. Currently, wells are not stimulated until scale buildup causes flow to cease entirely. Through the analysis of 32 acidized wells in the Spraberry Driver Unit, this paper defines a stimulation screening method...

..., Richardson, TX 75083-3836, U.S.A., fax 01-972-952-9435. Abstract In mature, multi layered reservoirs with commingled, dual string, and gravel packed completions, selecting reliable acid stimulation candidates has always been a challenge. Achieving a high success ratio under these conditions requires a risk...
