A case study is described in which facilities design is shown to play an important role in providing sources of carbon dioxide (CO2) for the gas-handling process. The challenges associated with bulk CO2 storage, compression, transportation, and injection are also discussed, and an evaluation of existing technologies for CO2-handling facilities is conducted.
Introduction
A company initiated its first pilot project of CO2 injection as a tertiary recovery mechanism in mid-2015. The target reservoir was one of the largest oil fields in the area. The objective of this project was to assess the feasibility of CO2 injection into a carbonate formation and estimate potential additional recoverable oil. The company intended, on the basis of the project outcomes, to set its future strategy for CO2 injection as a tertiary recovery mechanism.
