Plug breaker

A plug breaker system (100) comprising:

• a plug breaker (10) comprising a breaker body (11), a pressure catcher (12) arranged on the breaker body (11), a breaker object (15);
• and
• a plug assembly (30) comprising a plug (31), supported by a seat (32);
• and
• a breaker tubular (20) comprising an upstream tubular portion (21) and a downstream tubular portion (22), wherein the upstream tubular portion (21) is located upstream of the plug (31) and the downstream tubular portion (22) is located downstream of the plug (31);
• a channel (18) and a channel block (19);
• wherein the channel (18) is in fluid communication with the channel block (19);
• wherein the plug assembly (30) and the plug breaker (10) are arranged in a housing (23) within the breaker tubular (20);
• wherein the channel block (19) has an open position and closed position, and the channel block (19) is arranged such that:
• there is no fluid communication through the channel block (19) and into channel (18) in the closed position, and
• there is fluid communication through the channel block (19) and into the channel (18) in the open position;
• wherein the channel block (19) is arranged to move from the closed position to the open position when the release mechanism (13) releases, and
• wherein fluid in the channel (11) is arranged to move the breaker body (11) when the channel block (19) is in the open position.

A plug breaker system (100) comprising:

• a plug breaker (10) comprising a breaker body (11), a pressure catcher (12) arranged on the breaker body (11), a release element (13), a breaker object (15);
• and
• a plug assembly (30) comprising a plug (31), supported by a seat (32);
• and
• a breaker tubular (20) comprising an upstream tubular portion (21) and a downstream tubular portion (22), wherein the upstream tubular portion (21) is located upstream of the plug (31) and the downstream tubular portion (22) is located downstream of the plug (31);
• wherein the breaker body (11) and breaker object (15) are separate unaffixed elements;
• wherein the plug assembly (30) and the plug breaker (10) are arranged in a housing (23) within the breaker tubular (20);
• wherein the plug (31) is downstream from the breaker body (11);
• wherein the plug breaker system (100) is arranged to have a first position and a second position:
• in the first position, the release element (13) is arranged such that the breaker body (11) is stationary and the plug assembly (30) is stationary with respect to the breaker tubular (20), and
• in the second position, the breaker body (11) is arranged such that when the release element (13) releases, the breaker body (11) moves downhole, and the breaker object (15) breaks the plug (31).
