A method and apparatus for completing a horizontal hydrocarbon well includes cementing a casing string in the well and creating passages through the casing string adjacent float equipment near the casing toe by slowly dissolving a plug with completion fluid used to pump cement into an annulus between the casing string and bore hole. By the time the cement sets up, the plug dissolves leaving passages in the casing string through which a first frac job may be pumped or which allows pumping perforating equipment into the horizontal leg without requiring a coiled tubing run. The technique can also be used in vertical wells to save a perforating gun run. |
