Discover why PLAXIS is essential for oil, gas and offshore energy

Due to PLAXIS’ broad range of capabilities across the oil, gas and offshore industry chain and its efficient workflow, it removes the need to maintain several different software packages, improving productivity and reducing project and software maintenance costs. PLAXIS offers a full solution for the oil and gas industry ranging from geomechanical to geotechnical analysis. Geomechanical applications include reservoir and wellbore scale analysis of borehole stability or reservoir depletion. 

Geotechnical applications include stability and settlement analysis as well as seismic design of industry infrastructure. PLAXIS offers all these capabilities in just two separate finite element programs for two-dimensional and three-dimensional analysis, with options to integrate the software into existing workflows and couple it to your essential software infrastructure. PLAXIS also offers solutions for analyses involving very large displacements and material flow, which cannot be tackled by the traditional finite element approach.


PLAXIS for offshore wind

PLAXIS MoDeTo (Monopile Design Tool) employs results of the PISA joint industry research project, towards an improved design methodology for monopile foundations of offshore wind turbines. It enables a significant reduction in the amount of steel required for each monopile and, therefore, in fabrication, transportation and installation costs.

PLAXIS MoDeTo reaches its full potential when used in connection with PLAXIS 3D, which enables the automatic calibration of the soil reaction curves to the specific characteristics of the site. In addition, PLAXIS 3D offers a complete, well proven and robust finite element solution for any type of offshore or onshore structure. With its broad range of capabilities, multi-core calculations and 64-bit architecture, PLAXIS 3D along with its add-on modules, 3D PlaxFlow and 3D Dynamics, can deal with the largest and most complex geotechnical models, including jackets, tripods and suction anchors.

PLAXIS for oil and gas infrastructure

PLAXIS can also be used to perform settlement and bearing capacity analysis for onshore infrastructure like petrochemical plants or LNG tanks. Advanced material models in PLAXIS automatically account for different loading conditions of the soil encountered in excavation and foundation works. Plate elements and anchors elements can be used to model any necessary on-site excavations and pile fields for foundations can be easily constructed with embedded beams and the array tool. Loads from the superstructure can be modelled as well via point, line or surface loads. Via the staged construction mode, the building process can be simulated in a realistic way. With the design approaches facility SLS and ULS analyses can be performed by using the partial factors approach, adhering to for example EUROCODE or other partial factor based design codes. PLAXIS can also be applied in onshore and offshore pipeline movement and stability under various applied loading conditions.

PLAXIS for reservoir geomechanics

PLAXIS can be used for the analysis of wellbore stability, and for two and three dimensional reservoir depletion scenarios to assess surface settlements, but also stress redistribution in and around the reservoir which could potentially affect sealing properties of faults bounding the reservoir. Constitutive models in PLAXIS benefit from a full poroelastic formulation with Biot alpha factor, and range from simple linear elastic models to advanced non-linear models, for example the Visco-elasto-plastic model, which allow for accurate prediction of these stress changes and settlements

PLAXIS for offshore geotechnics

In offshore geotechnics, most problems benefit from three dimensional analyses as it fully captures the complex interplay between the soil and structures under various loading conditions, and its effect on change in stresses and pore pressures. PLAXIS offers several constitutive models dealing with undrained soil behaviour encountered in offshore engineering, to accurately model these processes, for example the NGI-ADP model and the soft-soil or soft soil creep model.
