System and method for compensating for attenuation of seismic energy

A computer system, comprising:

• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions that when executed by the one or more processors cause the system to:
• a. receive, at the one or more processors, a seismic dataset D(s, r;
• t) representative of a subsurface volume of interest;
• b. calculate pre-migration attenuated travel time t(s, r;
• t);
• c. perform a first migration on D(s, r;
• t) to generate common image point (CIP) gathers G(x, h) wherein x is subsurface image point and h is angle or offset;
• d. perform a second migration on D(s, r;
• t)*t*(s, r;
• t) to generate weighted common image point (CIP) gathers Gt*(x, h);
• and
• e. calculate a conditioned ratio of the weighted CIP gathers Gt*(x, h) over the CIP gathers G(x, h) to get CIP gathers of attenuated traveltime t*(x, h) wherein the conditioning prevents division by zero.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device with one or more processors and memory, cause the device to:

• a. receive, at the one or more processors, a seismic dataset D(s, r;
• t) representative of a subsurface volume of interest;
• b. calculate pre-migration attenuated travel time t(s, r;
• t);
• c. perform a first migration on D(s, r;
• t) to generate common image point (CIP) gathers G(x, h) wherein x is subsurface image point and h is angle or offset;
• d. perform a second migration on D(s, r;
• t)*t*(s, r;
• t) to generate weighted common image point (CIP) gathers Gt*(x, h);
• and
• e. calculate a conditioned ratio of the weighted CIP gathers Gt*(x, h) over the CIP gathers G(x, h) to get CIP gathers of attenuated traveltime t*(x, h) wherein the conditioning prevents division by zero.
