...) and inclination (INC) of the wellbore trajectory, controllable drilling parameters, unconfined compressive strength (UCS), formation pore pressure, and in-situ stresses of the studied area were included as inputs. The second step was by optimizing the process using a genetic algorithm (GA), as a class...

... Abstract The drilling of shallow horizontal wells in unconsolidated sand formations faces the particular challenge of achieving proper well trajectory, needed that minimizes dog leg severity and if not accomplished can increase well intervention frequency. These well complexity challenges may...

... of SAGD technology. Wellbore trajectory excursions or undulations- unintentionally generated trajectory deviations due to suboptimal drilling operations- are some of the complications that lead to non-uniform steam chamber conformance, high cumulative Steam-Oil Ratio (cSOR) and low bitumen recovery...

... from bottom since drilling the lateral section, which was not the response of base of 1B sand. So it was recommended to go down in stratigraphy in order to place the trajectory at the bottom part of 1B sand. In order to minimize wellbore stability issue along the lateral section, Bakerhughes...

... with slotted liner. Pre-job coordination meetings, Daily briefings, usage of Rotary Steerable System, Geo-Steering and Mid-course correction of trajectory based on Real Time Data Monitoring resulted in well placement in sweet spot. Well by well, rig days got reduced, lateral lengths increased, tangent...
