ENERGY TRANSITION | Carbon Capture (CCS/CCUS) Capabilities in OWD today
Digital Transformation ensures competitiveness of Oil and Gas, and enables the Energy Transition
Carbon capture, utilization and storage (CCUS) on a large scale will require technology development and expertise from both the Subsurface and Drilling domains. Oliasoft WellDesign (OWD) was developed in close collaboration with key partners in the oil industry and academia to create a modern and streamlined design tool for any type of well, production, injection or exploration. No matter the target, oil, gas, water, salt, coal or geothermal; Oliasoft has expanded OWD to contain industry specified features for CCUS well planning and design to aid analysing the following challenges:
- Storing and monitoring CO2 in offshore reservoirs
- CO2 wells technology
- Re-use of reservoirs and infrastructure
PROVEN CCUS CAPABILITIES IN OLIASOFT WELLDESIGN:
- Thermal simulator with capability to model injection of single state CO2 (with impurities) as liquid or gas state (includes thermal propagation)
- Multistring analysis with the option to add and remove fluids in any annuli
- Calculate formation vacuum in annuli when injecting fluids at any temperature
- Ability to mix fluids together in annuli, e.g. drilling mud and MEG
- Ability to simulate CO2 blowout
Oliasoft WellDesign enable the energy transition
Oliasoft make use of knowledge, expertise, and technology from oil & gas and software development to enable the energy transition in two ways:
1. Leveraging domain expertise
Oliasoft has collaborated strategically with research institutions and industry subject matter experts to develop unmatched functionality and usability for designing hydrocarbon wells. Taking advantage of the unique knowledge and insights to include functionality supporting planning and designing CCUS wells.
2. Modern software technology
Founded in 2015, Oliasoft has built OWD using modern software technology with the ambition to encourage and enable innovation. The technological foundation readily integrates new functionalities and requirements and now supports new use cases such as CCUS well design
Today, these two factors have made it possible for Oliasoft to integrate unique features for designing CCUS wells. The OWD tubing design module performs advanced thermal modelling and multistring analysis for any well configuration – handling production and injection of any fluid, both hydrocarbons and liquid CO2, with a range of impurities. The blowout and kill module perform stochastic blowout and dynamic kill calculations according to the latest industry guidelines. Further, this functionality also supports blowout simulation of liquid CO2 and subsequent kill operations.
New tools and technology need to evolve to fully plan and monitor CCUS wells. Oliasoft WellDesignTM is continuously being developed and refined to address this and the energy transition with applications based on the latest science, deployed through cloud-based technology, readily available to communicate with other systems, and negating the limitations and legacy issues of traditional native applications.
Digitalization entails transitioning from multiple “one purpose, one goal” applications to a structure of interconnected and flexible applications which integrate seamlessly to share data and provide valuable insight allowing for more outcome-centric operations.
Using Oliasoft WellDesign when planning Carbon Capture and Storage wells
Oliasoft WellDesign (OWD) is a modern integrated and seamless cloud engineering software application that connects every link in the well planning calculation chain and adheres to all regulatory requirements for well construction engineering. The OWD tubing design and blowout and kill modules contains unique industry specified features for CCS well planning and design.
The tubing design module can perform advanced thermal modelling and multistring analysis for any well configuration. Its thermal simulator has full capability to model injection of liquid CO2 with a range of impurities.
The blowout and kill module is the only commercial software that performs stochastic blowout and dynamic kill calculations according to the latest industry guidelines. The functionality also supports blowout simulation of liquid CO2 and subsequent kill operations.
Using Oliasoft WellDesign as a tool for designing CCS wells
Oliasoft WellDesign currently consists of six modules which cover all regulatory calculations needed to perform well planning. The software fully integrates the modules with data flowing freely between them – removing the need for reentry of data.
The application is built on top of an extensive library that, amongst others, contains predefined CO2 fluids, both pure and impure. The library also supports addition of custom fluid files, either by uploading an OLGA format tab file or by defining a custom fluid composition. Currently, the hydrocarbon equation of state is applied when defining a CO2 fluid in the hydrocarbon library.
When using the thermal simulator in the tubing design module, CO2 can be selected as the applied fluid for production and injection simulations. The chained simulation functionality further allows these results to be used as the initial condition when simulating waiting or shut-in operations. The thermal simulator has full capability to model liquid CO2, including the full phase envelope of CO2 and the Joule Thompson effect from gas expansion.
Multistring analysis includes annular fluid expansion and annular pressure build up. In addition to negative fluid expansion, the functionality supports addition and removal of volume from any annulus, both before and after a thermal change.
Oliasoft WellDesign is continuously being developed and refined, both internally and in collaboration with other companies. Implementation of the Span & Wagner model, a full equation of state specifically for CO2, and dual phase calculations are currently in the pipeline.
