New challenge to optimize wells drilling using the geomechanical model design

Abstract:

The objective of this project is to develop a geomechanical model based on porosity oil well logging from selected wells in ESPOL (Escuela Superior Politécnica del Litoral) field and to study the stability of the wells in Block 57 of the North Oriente Basin, in order to optimize future drilling in the Paleogene in the intervals of the Oligocene and Eocene with the aid of an optimum operational drilling window, focused on the TIYUYACU formation due to the high content of arcillosity it presents. The methodology of this project is based on: 1) Information selection, 2) Geological analysis, 3) Estimation of pore pressures, fracture and main well stresses, 4) Estimation of the mechanical properties of the formation, 5) Fault analysis with the Mohr Coulomb criterion, 6) Determination of the optimal operational window. This information will be useful for calibrating and optimizing the operational window for drilling muds, for future vertical and directional wells, both in the field of study and in neighboring oil fields.
