With our Solution Analysis tool you can test any rig against one of our generic wells or your own custom made well, and apply emission reduction systems like energy software, hybrid systems, closed bus, drilling efficiency equipment, alternative fuels and exhaust gas cleaning to name a few.
In addition, you can add fuel cost and emission taxes and the tool will give you a brief economic summary, including system cost.
Our Emissions Analytics and Contract Analytics tool displays a user defined selection from a single rig to the world fleet, from history to future projected emissions.
In addition, the Emissions Forecasting tool will help you compare present years’ emissions to next years’.
With emission profiles you can benchmark rigs against the same baseline
Drilling programme emissions give you the opportunity to select emission favourable rigs and plan your future drilling campaigns on a sustainable basis
Custom well profiles let you build your own well according to your own specifications and test emissions based on this
With the Solution Analysis tool, you can explore emission reduction initiatives and pay-back times

Whether you work for a bank, financial institution, investment fund, insurance company, consultancy, oil and gas operator, or drilling rig owner, rig emissions are a critical aspect of the offshore rig market. Emissions will be part of the foundation for any decision, whether it is portfolio, investments, access to capital, contracting, supply/service planning, reporting, strategy and more.
The system is divided into three modules:
We use the well program parameters for each section to calculate the duration of each section. Each section is divided into activities (drilling, tripping, cementing etc.) and we use the parameters from the well program such as ROP (rate of penetration), tripping speed, section length to calculate the time for each activity based on rig specific parameters.
The model outputs the time for each section and activity within the sections which then is summarized for the total well. WOW (waiting on weather), NPT (non-productive time) and a time efficiency factor are then added to the total well time to give a more accurate representation of the total time.
For the purpose of this model, 3 different types of wells have been pre-defined for each relevant geographical area. The 3 different types defined are development, exploration and P&A which can then be used to benchmark different rigs against each other.
In addition, the Greenpact Rigs model is fully transparent allowing for customized wells with specific parameters as decided by the client. This will allow for a more accurate representation for a specific well when benchmarking different rigs.
There is a specific amount of energy required to perform the work to drill a well such as lifting a certain amount of drill pipe/casing, pumping a certain volume of mud with certain pressure, rotating the drill string with a certain torque and so on. This information is used to calculate the power required for the drilling related equipment for each activity within each section using standard power calculation formulas for motors and pumps.
The power required for each equipment is then averaged for each section and the average power usage for each equipment is then used for the power consumption for each activity.
Based on data gathered from rig designs we can estimate the amount of power each rig design requires in auxiliary systems. The power usage for auxiliaries have been calibrated based on actual power consumption data from the field and are being constantly evaluated to be as accurate as possible. Auxiliary loads include marine systems (cooling and compressors loads), HVAC, LQ as well as winterization if applicable.
When designing a rig for dynamic positioning, it’s important to know the maximum expected load on the thrusters to be able to size the thrusters according to defined maximum weather criteria. The force on the thrusters is depending on the hull geometry for wave and current loads and the topside structures for the wind load.
For each semi-submersible and drillship design, force coefficients for the wave, current and wind loads are defined based on previous design experience (including model tests and CFD (computational fluid dynamics) analysis). These coefficients are then used with six representative data points from weather data for different locations to calculate the thruster force for each data point. The forces are then summarized in accordance with the frequency of occurrence for each weather to give a representative average thruster force.
The thruster force is then converted to thrust using the ABS (American Bureau of Shipping) bollard pull formula including efficiency and thruster interference factors based on design experience.
Since the drilling loads are based on the well itself, the total work required to drill a well is the same for all the rigs. However, since different rigs have different auxiliary loads, different types of drilling equipment and drill wells with different efficiency the fuel consumption per day is different. As an example, if one rig takes 40 days to drill a well and another rig takes 45 days to drill the same well the amount of power usage for drilling is the same but the rig that takes longer will have a lower power consumption per day.
There are different types of equipment/systems that could be installed on a rig to make it more energy efficient. These are equipment like energy saving systems (ESS) for peak shaving of the load curve on the rig, super capacitor packs to take the load from the draw-works when tripping, heat recovery from exhaust etc. The different energy saving systems are implemented in the model by defining an energy saving percentage for each module (Drilling, Aux and DP) as different systems will impact the rig differently (as an example, super capacitors could only impact drilling equipment and as such no energy would be saved on the rest of the rig).
By using this method to define the energy saving percentages the energy efficiency module is highly customizable which will allow the user to make the energy saving calculations as accurate as possible.
