System and method for automatically correlating geologic tops

A method for automatically correlating geologic tops using at least one processor, the method comprising:

• receiving a first well log and at least a second well log;
• receiving at least one seed pick designating a particular sequence of data in the first well log as a well top;
• adding, by the processor, the at least one seed pick to a confidence priority queue, wherein the confidence priority queue is configured to assign a priority based on a confidence value and wherein at least one seed pick is assigned a maximum priority and wherein the confidence value of the pick is a non-increasing function of path length from the at least one seed and a non-increasing function of a quality of the pick;
• determining, by the processor, at least one neighbor for each well log;
• defining, by the processor, a highest confidence series of well top picks by traversing the confidence priority queue until the queue is empty by retrieving a first element from the confidence priority queue and removing the first element from the queue, determining a new pick by performing correlation on each neighbor of the first element, assigning the new pick a pick quality value, adding the new pick to the confidence priority queue according to the confidence value and generating the highest confidence series of well top picks;
• and
• displaying, on a display connected to the processor, a result of generating the highest confidence series of well top picks.

An apparatus, comprising:

• a computer system having at least one processor, memory and display, wherein the processor is configured to:
• receive a first well log of a first well bore and at least a second well log of a second well bore;
• receive at least one seed pick designating a particular sequence of data in the first well log as a well top;
• determine at least one neighbor for each well log;
• and
• define a highest confidence series of well top picks by retrieving a highest confidence pick wherein the confidence of the pick is a non-increasing function of path length from the at least one seed and a non-increasing function of a quality of the pick, determining a new pick by performing correlation on each neighbor of the well log, assigning the new pick a pick quality value and generating the highest confidence series of well top picks;
• and
• the display displaying a result of generating the highest confidence series of well top picks.
