pairs, with one well utilized for injection and the other for production. A set of 
wells is widely employed for both injection and production in shale/tight 
reservoirs. This method is known as a huff-n-puff (HNP) process, and it is 
more successful in systems with highly heterogeneous permeability, such as 
multi-fractured horizontal wells (MFHWs) with a stimulated reservoir volume 
(SRV) based on investigations. (Jacobs, 2022) An injection period (huff), a 
soaking period, and a production period (puff) are all parts of the HNP 
process, which may be repeated several times. In the injection procedure, a 
variety of gases might be employed. However, due to its lower minimum 
miscibility pressure (MMP) than other injection gases, 
𝐶𝑂
has been 
demonstrated to be a better injection gas via experimental and modelling 
study. However, one of the key reasons for assessing the usage of generated 
natural gases for field applications is the related expense of collecting and 
injecting 
𝐶𝑂
. MMP is the minimum amount of pressure that it is possible to 
have miscibility in terms of both multi and first contact. (Jacobs, 2022) (Wang, 
2022) (Hamdi, et al., 2022)
For a single well, Huff-n-Puff is more workable and practical considering 
the low cost with a high return feature with the faster response than other 
methods
. 
Huff-n-Puff is not displacement process, for this reason, it is 
effective especially for tight reservoirs, as gas is mixing with oil to swell it 
here the possible maximum mixing of injected gas with the oil is more 
important. (Wang, 2022)
