Correlation Issues Gamma Ccl Log Top Gun Oilfield Training Center In this video, we delve into some of the common scenarios where your casing collar log (ccl) depth might not align perfectly with the gamma ray log depth, or vice versa. we'll explore a few. Gamma ray and collar logs are used to correlate our depth measurements back to the original open hole and cased hole logs that were run during well completion. it is imperative that we have a copy in the field during our test. one serious trap to avoid is the "here's the last log we ran" syndrome.
Correlation Issues Pdf Dependent And Independent Variables The casing collar locator (ccl) is an important tool because it is used for depth control. when combined with a gamma ray log, it allows depth correlation of a cased hole logging run with the openhole logs and, therefore, reservoir units or zones. The two primary cased hole logging tools used for deoth control are the gamma ray (gr) and the collar locator (ccl). the gr can be correlated with previous open hole logs to tie into the reservoir zone of interest. It describes using gamma ray and casing collar logs to correlate depths and ensure perforations are at the desired intervals. proper job preparation, running tools in hole while logging, tying into correct collars above and below the zone, and verifying stop depths are essential to prevent off target perforations. In this video, we delve into some of the common scenarios where your casing collar log (ccl) depth might not align perfectly with the gamma ray log depth, or vice versa. we'll explore a few potential reasons for this discrepancy.

A procedure to automatically correlate well logs measured in boreholes that are located in continental siliciclastic basins by using two different methods is shown. Unlike the sp log, which is used in a single linear relationship between its response and shale volume, the gamma ray has several nonlinear empirical responses as well as a linear response. The th k and th u ratios were also plotted as logs together with the gamma ray trace and a graphic lithology log from the description of drill cuttings. the simultaneous consideration of these data throughout the sequence reveals striking and readily interpretable patterns. The weatherford telemetry gamma ray and ccl is a combined gamma ray and ccl tool with a telemetry control unit which provides a passive measurement of gamma radiation by means of a sodium iodine scintillation detector and identifies changes of metal thickness by means of a collar locator.
