Publication number: 20210133367Abstract: System and methods for optimizing wellbore tubular design are provided. Design parameters for a wellbore tubular component are determined based on different types of axial loads expected during a downhole operation. The design parameters include load conditions at load points along the tubular component. An equivalent axial load is calculated for each load point, based on the corresponding load conditions. Design limits for the different types of axial loads are determined based on associated design parameters. A counter-load pressure is determined for at least one load point selected for each type of axial load, based on the corresponding equivalent axial load for each load point and a corresponding design limit for each type of axial load. At least one of the design limits is adjusted for the different types of axial loads, based on the counter-load pressure of the selected load point for each type of axial load.Type: ApplicationFiled: June 16, 2017Publication date: May 6, 2021Inventors: Zhengchun Liu, Robello Samuel, Adolfo Gonzales, Jenny Xie, Yongfeng Kang

Patent number: 10428639Abstract: Damage to a casing string in a wellbore resulting from a wellbore operation can be predicted. For example, a stiff string model can be used to determine a contact point between the casing string and a well tool positionable within the casing string for performing the wellbore operation. The stiff string model can be used to determine a force of the well tool against the casing string at the contact point. The force can be used to determine a volume of damage to the casing string proximate to the contact point. A depth of a groove formed in the casing string proximate to the contact point can be determined based on the volume of damage.Type: GrantFiled: September 15, 2016Date of Patent: October 1, 2019Assignee: Landmark Graphics CorporationInventors: Aniket, Adolfo Gonzales, Robello Samuel, Robert D.

Patent number: 10380281Abstract: Systems and methods for determining vector-ratio safety factors for wellbore tubular design are provided. Pressure and temperature data for at least one load point along a tubular component of a wellbore are obtained. An effective failure axial load expected at the load point is calculated during a downhole operation to be performed along one or more sections of the wellbore within a subsurface formation, based on the obtained data. An upper boundary and a lower boundary for the effective failure axial load are determined, based on physical properties of the tubular component at the load point. A midpoint of the effective failure axial load is calculated based on the upper and lower boundaries. A critical failure differential pressure is calculated, based on the midpoint of the effective failure axial load. A vector-ratio safety factor is calculated, based on the critical failure differential pressure relative to the effective failure axial load.Type: GrantFiled: November 22, 2016Date of Patent: August 13, 2019Assignee: LANDMARK GRAPHICS CORPORATIONInventors: Zhengchun Liu, Robello Samuel, Adolfo Gonzales, Yongfeng Kang
