| Summary: | The drilling process in petroleum industry is directly proportional with economics and if even a small
problems encounters on any point during drilling will might results a commercial loss (i.e. economics and time
factor). This study is based on the study of all those hindrances/problems often encounters during vertical
drilling and ways to combat against those problems. Now, these days although the drilling have been an
advanced practice but the problems are still of same nature like (bore-hole instability, loss-circulation, drill pipe
sticking, gas cuts in a shallow formation, salt dome, kick and back flow). This study focuses above problems
which are not natural but it is due to human error or may be the improper handling of the tool during the
operation but these are critical with reference to the time factor and also budgeting is there. So, if these occur
then the possible remedial actions in order to save the time factor as well as the economics are kept and handled
accordingly. This may involve, the proper design of drilling components regarding given geophysical data of
formation, proper usage of drilling fluid to avoid bit balling, formation sloughing, maintaining hydrostatic
pressure and proper usage of blow out preventor to control abnormal pressures, so that a good drilling
performance will be taken into account by setting up a benchmarking process that is termed to be as “a
necessity for survival”. |
