Casing and cementing design as well as mud planning are required to be done prior to drilling a well. This concern is closely related to the success and attainment of effective and efficient drilling operation. The present final project examines those issues for Well Matoa-7R. <br /> <br /> <br /> Well Matoa-7R is a substitution well for previous Well Matoa-7 that used to use an electric submersible pump (ESP). It was discovered that when the pump is needed to be repaired, it could not be pulled out of the hole even after a fishing job. This was because the well collapsed at a depth of 6046 ft. The well was then abandoned. Consequently, a well must be drilled near Matoa-7 since the well is believed to still have high potential of production. The substituted Well Matoa-7R was drilled at a location of only 10-meter away from Matoa-7. <br /> <br /> <br /> Specific characteristic of Well Matoa-7R, e.g. high temperature (2200F) with total depth of 9650 ft, have challenged the operator to carefully plan the next drilling operations. Evaluation on casing and cementing design as well as mud planning of Well Matoa-7R is then essential. Results of this evaluation were compared to the actual drilling operation completed for Well Matoa-7R. New designs for the three issues were the final result of the present study
