A gel plug of vegetable oil, fatty acid, a particulate filler such as calcium carbonate, and an optional base and/or polymer. The gel plug can be employed during construction of an offshore pipeline to separate a gas-filled portion of the pipeline from a waterflooded portion, and to facilitate control and movement of a gas/gel plug/water interface as desired to assist in construction operations. Furthermore the gel plug can be used for sealing the ends of a towable pipe section. |
