Wellbore Trajectory Optimization Using Rate of Penetration and Wellbore Stability Analysis

SPE International Heavy Oil Conference and Exhibition, 2018
Abstract Drilling deviated wells is a frequently used approach in the oil and gas industry to increase the productivity of wells in reservoirs with a small thickness. Drilling these wells has been a challenge due to the low rate of penetration (ROP) and severe wellbore instability issues.

Modeling Thermal Effects on Wellbore Stability

Proceedings of Trinidad and Tobago Energy Resources Conference, 2010
Abstract Field evidence indicates that the thermal regime in wellbore considerably affects the wellbore stability in directional and horizontal wells. However, the temperature effects have not been investigated thoroughly in existing literature, and the effects of drilling fluid flow and various heat sources on the behavior of formation ...

Wellbore Stability Evaluation for Mishrif Formation

SPE Middle East Oil & Gas Show and Conference, 2017
Abstract During drilling operations for the E oilfield in the Mishrif formation in southern Iraq, stuck pipe has been identified as a significant geomechanical problem for several wells. In this study, a 1-D mechanical earth model (MEM) of the Mishrif formation is compiled based on its state of stress and rock strength parameters and is ...

Wellbore Stability in Fractured Rock

IADC/SPE Drilling Conference and Exhibition, 2010
AbstractNumerous wellbore instability problems related to drilling through potentially fractured formations have been reported. Often, these rocks are characterized by the abundance of macro and micro scale bedding planes and/or networks of natural fractures.

Guidelines for efficient wellbore stability analysis

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1997
Abstract The key factors which contribute to wellbore instability problems in oil and gas fields can be grouped as non-changeable and changeable. Non-changeable factors include the in-situ stress regime, pore pressures and the mechanical and strength properties of the formation and its bedding planes.

Wellbore-Stability Performance of Water-Based Mud Additives

SPE Drilling & Completion, 2008
Abstract A critical property for many water-based muds is the ability to prevent near-wellbore pore pressure increase in shales. By slowing or preventing this pressure increase, a true overbalance pressure is maintained, which promotes wellbore stability.
