Wireline conveyed casing test plug with a burst disk and pressure test tool assembly

A casing pressure test tool assembly, comprising:

• a well extending from a top end to a downhole end, the well having a receptacle formed by a shoulder protruding inward into the well, a diameter of the receptacle is smaller than a diameter of the well directly above the shoulder, the receptacle positioned between the top end and the downhole end;
• a wireline setting tool configured to be run into the well;
• a casing test plug positioned downhole of the wireline setting tool, the casing test plug having a plug body with an exterior surface extending from a first end to a second end, a bore extending at least partially into the plug body, and a burst disk secured within the bore;
• and
• a wireline setting tool adapter connecting the wireline setting tool and the casing test plug, the wireline setting tool adapter releasably attached to the casing test plug within the bore;
• wherein the casing test plug is configured to release from the wireline setting tool adapter upon application of a separation force between the wireline setting tool adapter and the casing test plug;
• wherein the casing test plug is configured to seal within the receptacle of the well;
• wherein the exterior surface of the plug body and the receptacle are configured to come into contact to create the seal within the receptacle without utilizing any articulating sealing or locking components;
• and
• wherein after the casing test plug is sealed within the receptacle, the burst disk is configured to withstand pressure up to a rupture burst pressure, such that pressure can be applied from the well surface to test casing integrity.
