Campbell, A E

This apparatus supplies foam for use as a circulating fluid in a well. A foam generator is connected to a source of gas and a source of liquid foamable solution. The generator includes a tubular member having a gas- foamable solution entry formed at one end and a foam exit formed at the other end. A helical insert is located within the tubular member to provide a swirling action and to cause the gas-foamable solution to be intimately mixed to form a stable foam at the exit end thereof. The exit end of the tubular member is connected to either a tubing string or to a well annulus for circulating the foam in a well. (3 claims)
