Frequently Asked Questions
What makes GasAssure unique?
GasAssure enables a user to plan the entire supply chain, from reservoir to the final market in one go and generates a solution in a fraction of time taken by current offerings. A user can track the hydrocarbon at any stage of the supply chain. By allowing for the changing field and operating conditions, GasAssure is suitable for short, medium and long-term planning.
GasAssure is market driven, enabling the user to prioritise markets, plan additional drilling of wells in the case of peak demand or maintenance shutdown, ensuring that gas contract obligations are met.
How is Gas Planning Currently Done in the Oil & Gas Industry?
While a large part of the Oil and Gas Industry still rely on Excel spreadsheet formulation for Gas Planning, software solutions are gaining ground due to their large data handling capacity, accuracy, easier bug identification and efficient reporting
Currently, different software packages are required to model reservoirs, wells, process plant, compressors, pipelines and the final market. Some companies offer software which can only model and simulate a specific part of the upstream supply chain, while others offer software which can be integrated to give a seamless upstream supply chain model.
What makes GasAssure so much faster than other solutions?
Can I integrate GasAssure with other software for data input?
How do you model 2 – 3 phase flows in a tank ( say gas and water productions from the same tank?) in GasAssure ?
There are different ways to handle Oil in GasAssure:
For gas and gas-condensate: One way is to deal with oil as their equivalent gas volume at surface condition. Due to program being fully compositional, Having defined the composition, products such as Condensate can be defined. Once it gets to the reporting side, condensate products are converted to liquid units such as BBls, m3 etc.. This can be done using tank models and type curves.
Another way is to deal with C5+ components as oil which in this case oil in liquid form will be carried in the network using the multiphase flow correlations.
Third way is to calculate the amount of condensate based on pressure and temperature at each point in the network which that is done by integration of GasAssure with PVTsim Nova. This will depend on the user to have PVTsim Nova installed on their computers.
For Oil reservoirs having solution gas or free gas: This can be modeled using Blackoil version of GasAssure called OilAssure. This can be done either on the tanks (coming in future versions) or as typecurves (Available in V1.6). OilAssure and GasAssure are integrated and user can join the Blackoil network to the compositional network (gas network/GasAssure) with a Flash table defined at the connection point. From the connection point to the market node, the model will be compositional.
Water production is modelled by adding H2O as a component in the network.
