Special cements are available to prevent annular gas flow, but if a leak still occurs, there are other methods for controlling the problem. This article discusses the leak prevention methods. If a production liner is to be run, and the pay zone near the bottom is known to have annular gs flow potential, then consideration could be given to cementing around the bottom of the liner while rotating or reciprocating. The liner top could then be squeezed with an anti-gs migration cement if gas shows up in the mud when circulating bottoms up. If there is no gas feeding in, then the top could be squeezed with regular low water loss content. (Gas migration could be determined by monitoring gas in the mud with a gas detector while waiting on cement. As discussed in an earlier article, the drill pipe should not be pulled out of the hole for six to eight hours after the primary job in the event that gas gets through the cement and the well kicks.
