Modular workover and drilling platform rigs have played an important role in the development of existing oil and gas fields since the 1960’s. The past decade has seen tremendous design improvements in both workover and drilling operations. Improvements range from effective utilization of top drives for sidetracking and extended reach programs to minimizing weight and space distribution of the rig to accommodate minimal space platforms. Case history studies will illustrate how technological developments in modular rig design have increased an Operator’s invested return on their offshore platforms and hired drilling/workover rigs.
