Wellbore Cleaning is very important in drilling operations as well as successful completion of the well. The filter cake that remains in the wellbore after the drilling operation can cause an unstable barrier between the cement and wellbore and prevents the cement from being robustly attached to the wellbore. This can cause major accidents in the drilling operation, especially if it is not taken care of appropriately. There are many factors and methods that go into the cleaning of the wellbores. Brushes and scrapers are well known but are not efficient since they are time consuming and costly. More research needs to be done to make the wellbore cleaning operation more practical and efficient. Cleaning a wellbore after each usage is critical to ensure well-maintained production of oil at a steady rate. Cleaning a well is essentially removing the cuttings that are produced from the drilling process. These cuttings must be removed from the well to the surface where they are disposed. This research presents an investigation on the performance of surfactants added to drilling fluids for wellbore cleaning in carbonate fields.
