The use of graphene as a drilling mud additive may form mud cake as a filtration barrier, and the use of magnesium oxide (MgO) may increase the viscosity value. Therefore, research has been conducted on additives that can be used for water-based mud, making it equal or even superior in quality to oil-based mud. Previous research on drilling mud concludes that oil-based mud is the best drilling fluid, but is not recommended because it is unsustainable and environmentally unfriendly. 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. 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”.
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). Trying to find the balance, from Pressure and Friction issues. Straggly against the uncertainties by Drilling and Completion originates. Especially in directional drilling wells. Nowadays, the high demand by Operators to drill more wells, faster, safety and costly profitable, has become essential. 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.
