Drilling Optimization Using Software Algorizms and Mathmatical model Simulating Block 8 – Dindir – Sudan Drilling Operation

Abstract

The overall health of oil industry depend on reducing the cost of the drilling operation and enhance its performance. For attaining this, more experiences and awareness is needed. The target of this study is to optimize drilling operation and enhance its performance in one of the Sudanese field - Dindir area that suffer of very low rate of penetration by using three tools (land Mark Well Plan soft ware, Z. Aswad Model and Drilling Optimization Simulator soft ware). The study starts by collecting and evaluating the data for three explortion wells in dindir area. These data were introduced in to land mark well plan to achieve optimum hydraulics and flow properties then the output of land mark plus some parameters (like differential pressure, bit dullness, …) were applied in Z. Aswad drilling rate equation to achieve the optimum weight on bit and rotary speed. Pay zone simulator used to simulate actual drilling operation (history matching) then using the optimum parameters that was imported from Land mark and Z. Aswad model as a new scenario (optimum scenario). By Visualizing and comparing between the two field/modified scenarios the results showed the reduction in time/cost was in an average of 30%. That can be consider as the basic for drilling operations in this area
