Abstract:

A flow back process usable on a well during a drilling operation includes the steps of flowing the commingled well fluids and solids into a surface-mounted flow back system under wellbore pressure. Alternatively, a flow back process includes the steps of connecting a surface-mounted flow back system to the well while the well is in an underbalanced condition. The operation of sequentially drilling through each of a plurality of isolation plugs is then initiated while flowing the well fluids and plug fragments into a surface-mounted flow back system. In yet another aspect, a large particle filter includes a filter section, a monitoring assembly, a bypass system and a purge assembly. The large particle filter can be connected to a Christmas tree and used to remove plug fragments from commingled flow leaving the well during a drilling operation.
