Asphaltene Deposition during CO2 Flooding in Ultralow Permeability Reservoirs: A Case Study from Changqing Oil Field

open access: yesGeofluids, 2021
Asphaltene deposition is a common phenomenon during CO2 flooding in ultralow permeability reservoirs. The deposited asphaltene occupies the pore volume and decreases permeability, resulting in serious formation damage and pore well productivity.

Asphaltene precipitation trend and controlling its deposition mechanism

open access: yesNatural Gas Industry B, 2022
The B oilfield is a large integrated oilfield in the Middle East. Asphaltene precipitates from crude oil and deposits on solid surfaces, affording considerable blockages of the formation, wellbore, and production equipment.

Lubricant-Impregnated Surfaces for Mitigating Asphaltene Deposition [PDF]

open access: yesACS Applied Materials & Interfaces, 2020
Asphaltenes are heavy aromatic components of crude oil. Their complex chemical makeup-an aromatic core surrounded by aliphatic side chains-enables them to adhere to most surfaces. Their buildup in pipes can result in clogging and lead to interruption of production operations and expensive mechanical cleaning.

Numerical Validation of Asphaltene Precipitation and Deposition during CO2 miscible flooding

open access: yesPetroleum Research, 2020
Asphaltene precipitation, flocculation, and deposition can significantly reduce oil production by impacting wellbores, flowlines, and more importantly, formations’ pore space around the well.

Comparative Analysis of CO2, N2, and Gas Mixture Injection on Asphaltene Deposition Pressure in Reservoir Conditions

open access: yesEnergies, 2018
CO2 and N2 injection is an effective enhanced oil recovery technology in the oilfield especially for low-permeability and extra low-permeability reservoirs. However, these processes can induce an asphaltene deposition during oil production.
