A new prospect is planned to be drilled by Kenmac Petroleum Corporation on a new licensed Molly field located in the North Sea on Block 14a/b. The tasks involved in well planning are as follows: (a) the estimation and evaluation of pore and fracture pressure and their impact on well planning, (b) a lithology study of the different formations and the steps taken to minimize the occurrence of drilling problems through all different formations, (c) a casing scheme design, (d) a mud programme design for the given well, and (e) a cement type suitable for the application in the given well.
