Casing wear and pipe defect determination using digital images

A system, comprising:

• a data transceiver, capable of receiving input parameters including downhole conditions and at least one visual frame of a drill string, wherein the at least one visual frame is received from one or more image devices located at a surface location of a borehole undergoing a drilling operation, where the one or more image devices are not in contact with the drill string, the drill string is coupled to a surface equipment of the borehole, and the drill string is undergoing a trip in operation or a trip out operation at the borehole;
• a result transceiver, capable of communicating a casing wear parameter;
• and
• a casing wear processor, capable of using the input parameters to generate the casing wear parameter by calculating a metal wear on a section of casing, wherein each visual frame is analyzed by the processor for a surface change in a surface of the drill string, where the metal wear is determined utilizing the surface change, the section of casing is identified by correlating the drill string location in the borehole during an active drilling portion of the drilling operation and the drill string was in contact with the section of casing, the casing wear parameter is determined by correlating the surface change of the drill string to the section of casing, and the casing wear parameter is used to replace the section of casing or to modify a weight-on-bit, a drill string rotation rate, a drill string size, a mud density, a mud rheology, a mud velocity, or a pipe eccentricity.

A computer program product having a series of operating instructions stored on a non-transitory computer-readable medium that directs a data processing apparatus when executed thereby to perform operations, the operations comprising:

• receiving input parameters at a casing wear processor that include downhole conditions of a borehole and at least one visual frame representing a digital image of a first drilling pipe segment of a drill pipe undergoing a trip out operation from the borehole subsequent to a drilling job, wherein the at least one visual frame is captured at a surface location of the borehole and a device capturing the visual frame is not in contact with the first drill pipe segment;
• determining a depth range of the first drilling pipe segment, wherein the depth range corresponds to a location of the first drilling pipe segment in the borehole during the drilling job;
• determining a surface change of a surface of the first drilling pipe segment by analyzing the at least one visual frame;
• identifying a section of casing located in the borehole, that was in contact with the first drilling pipe segment, utilizing the depth range;
• determining a casing wear parameter by correlating the surface change to the section of casing utilizing the downhole conditions, a wear classification of the surface change, and a metal wear of the first drilling pipe segment determined using the surface change;
• and
• replacing the section of casing or modifying at least one borehole operation of the borehole utilizing the casing wear parameter by using one or more of adjusting a weight-on-bit, a drill string rotation rate, a drill string size, a mud density, a mud rheology, a mud velocity, or a pipe eccentricity.
