Abstract: Systems and methods include techniques for determining whether to use underbalanced coiled tubing drilling (UBCTD) or conventional drilling with hydraulic fracturing to drill a new well in deep and tight reservoirs with slow rate of penetration issues. Estimates of geomechanical properties and image log processing for past-drilled wells are completed first, then three-dimensional (3D) property modeling and natural fracture prediction (NFP) for the domain are conducted. Then a 3D geomechanics model is generated. After this the rock properties and NFP along the planned well trajectory are extracted. The diagenetic rock typing is evaluated. Required breakdown pressure for hydraulic fracturing is calculated. A determination based on the diagenetic rock typing and required breakdown pressure is made whether UBCTD or conventional drilling with hydraulic fracturing should be used for a new well.
