Abstract
Once a drilling system is established, there are only few parameters that can be altered or changed due to the system constraints and limitations. However; with the variation in encountered formation characteristics the optimum value of drilling parameters changes and during drilling only few operational parameters can be changed to their optimum values. The real time data is used to re-evaluate the optimum values of such parameters (RPM, WOB etc) by using simple analysis technique. With the help of this simple program the operator can change the characteristics to their respective optimum values and get maximum rate of penetration within allowable constraints. Thus, an increase in rate of penetration will ultimately reduce the drilling cost. These result in an economic, cost effective and efficient drilling operation.
The paper elaborates the above discussion, shows how simple program can analyze the on going drilling process and suggests recommendations to acquire better results.
