... ( Guangbin et al., 2021 ), and production profile predictions considering factors like wellbore friction, completion parameters, well trajectory, and permeability distribution ( Abdulwahid et al., 2014 ). Abstract Distributed temperature sensing (DTS) has been widely adopted in the real-time well...

... software was used to evaluate the risk magnitude and the observations were used to prepare a mitigation plan. All the well trajectories for both reservoirs were mapped inside the 3D reservoir structure. As a first case, a potential strike zone (PSZ) with a radius equal to the frac half-length was generated...

... for the first time in South East Asia region. Via integrated workflow, a thorough study integrating the data from multiple domains i.e. drilling data, well trajectory, petrophysical evaluation, pore pressure, cementing design and execution, effective mud removal, centralizers’ performance evaluation and cement...

..., the Reservoir Mapping While Drilling LWD (DDEM) tool, in combination with standard triple combo LWD (Logging While Drilling) tools, was deployed. This is to ensure that the well trajectory stays within the targeted sands and the bed boundaries are detected long before the drill bit exits the sand body. Unlike...

... and observed properties. Once drilling targets are risk-assessed on the basis of structural, fluid contacts, and properties uncertainties, the final well trajectories are designed by the drilling team. This study identified and ranked multiple undrained and appraisal areas. A full infill redevelopment...

... A mandatory step of any well placement process is to have a prejob modeling to simulate log response based on formation model and the planned well trajectory ( Griffiths, R. 2009 . Well Placement Fundamentals ). The formation model incorporates both the structural information...

... drilling has been achieved using conventional well placement method for the first time in this field. Well Placement workflow involves real time well trajectory designing while drilling based on layer earth model updation using LWD Image and Log data. The high resolution LWD images in real time have been...

... that integrate in-situ stresses, reservoir pressure and its depletion trend, rock strength, well trajectory, completion type and planned drawdown. Use of grossly empirical, often unreliable, methods to infer sand production risk could result in either unnecessary an upfront sand control cost or sand management...

Model Characteristics The reservoir was modeled using two layers with a Darcy model (average reservoir pressure, fluid and rock properties, and skin per layer). The planned dragon well trajectory...

... of the geological feature, and the dynamics within the horizontal wellbore, it is very challenging to reproduce the actual production profile in the simulation model. For example, an unfavorable combination of a sump (variation in depth) in the well trajectory and fluid holdups may prevent the toe from producing...

Based on the offset wells data, rotary steerable system with 4¾" size tool was expected to achieve at the minimum of 50% increase in daily drilling ROP i.e. 150 m/day while achieving...

... and actual well trajectories were continuously updated while drilling. The geological model was updated based on the comparison between real-time and modeled logs. Instructions regarding mid course corrections were conveyed to the drilling engineer at the rig. The technology helped to optimize the well path...
