Troubles during drilling the well are often occurred although it is supposed to be made proper drilling plan. On the other hand we can get newly gained knowledge from those troubles. Lessons learned from troubles must be sheared and conveyed for future drilling operations. The most important thing in any troubles in some situation is to make our own efforts to phlegmatically decide what to do, making the most of our knowledge or obtainable information about undergrand situation, as well as commanding our experience of troubles. Our own attitude that shows strong intention to solve problems is equally important.
JAPEX would like to introduce two cases of troubles especially during liner hanger setting operation. First is the liner setting tool assembly stuck after conducting 7″liner cementing job. Second is malfunction in releasing the liner setting tool from liner hanger.
