Well engineering simulation (WellPlanTM) challenges and uncertainties in drilling engineering

Abstract

The report work on this laboratory simulation, will be simulated a Drilling Operation to identify the challenges that this operation carries, and how to mitigated them. Nowadays, the high demand by Operators to drill more wells, faster, safety and costly profitable, has become essential. Especially in directional drilling wells. Straggly against the uncertainties by Drilling and Completion originates. Trying to find the balance, from Pressure and Friction issues. Being a well know, a common problem “the Natural Fracture”, will results in lost of circulation, which will lead to reduction in mud column (h). The challenge and the hazard, is the high probability of either going bellow the collapse gradient or the pore pressure gradient, which might result in “Kick” or “Blow out”. To carry out a good simulation, Design the right drill string (DS) and bottomhole assembly shall allow us to reduce the uncertainties and establish efficiency mud window during the Drilling Program plan and his implementation.
