An integrated approach for the planning and completion of horizontal and multilateral wells

The rules and the criteria required for selection of horizontal and multilateral wells were developed. The selection criteria for junction levels and for lateral-section completion were also formulated. These criteria were illustrated with logical flowcharts and a single matrix. These flowcharts and matrix were used to establish a systematic procedure for the planning and completion of horizontal and multilateral wells. This comprehensive process is illustrated by case studies. The final outcome is the design of fit-for-purpose horizontal and multilateral wells, with intelligent flow capabilities. itical factors affecting the selection of horizontal and multilateral well completion were identified. The decision to drill a horizontal lateral is affected by the coning potential and by the flow-capacity value. The selection of multilateral schemes is a complex function of both fluid and reservoir properties. The selection of the lateral-section completion equipment depends greatly on sand control requirements. The junction-level selection depends to a great extent on junction stability and on fluid flow control requirements.
