An important challenge in the oil industry is to transport crude oils through pipelines while minimising potential transport issues like formation damage and plugging of wellbores, production facilities, and pipelines due to asphaltenes agglomeration.
Asphaltenes agglomeration occurs when the equilibrium of the asphaltene and resins is altered due to the changing flow conditions during transportation. Since the viscosity of crude oil, which is a key governing parameter in fluid transportation in pipelines, and asphaltenes content are both closely related – any fluctuation in the temperature, pressure, and oil composition in the pipelines can easily trigger an industrial debacle.
The company is seeking chemical flow improvers i.e. surfactants, polymers, small molecules, etc., as well as analytical/computational methods to study the mechanism of asphaltenes agglomeration.
Chemical Flow Improvers
The transportation of highly viscous reservoir fluids is a demanding industrial task and chemicals like flow improvers are often added to tackle this issue. Here, the company is keen to explore viscosity-reducing chemical-based technology for super heavy oil. The chemical solution should have at least one of these capabilities:
Analytical or Computational Methods
Due to the complexity of petroleum, any thermodynamic modeling of the asphaltene precipitation requires many approximations and assumptions which is a challenge to provide a reliable predictive model. The company is keen to explore analytical and predictive technologies to understand agglomeration/dispersion mechanism in specific oil conditions with a focus on:
1. Analysis of the stability of asphaltene fraction in the production fluid matrix
2. Analysis of the agglomeration and dispersion of asphaltene in crude oil
3. Asphaltene deposition on / adherence to surfaces
Mechanical technologies i.e. pigging/scrapping tools, pipeline coating/materials
