The injection process will be in cycles with spesisified period. Previously, intermittent gas lift is modeled using nodal analysis method, which is intersection between inflow performance relationship (IPR) and tubing performance relationship (TPR) and mechanistic method. Both solutions required a hard-working numerical approach to solve the model. In this paper, a new-simple-effective analytical approach is introduced to solve a set of equations that was derived from Transport Reynolds Theorem. The work is slightly different from the Liao and Bordalo model. A complex equation that represents movement of the gas-column, the slug, and the film from surface to sub-surface is presented. Gas column is formed during the injection time and the injected gas will push the oil to the surface. The dynamics of the gas column greatly affect the success of the process of oil production with gas injection method intermittently. The gas-column pressure, surface injection pressure and rate, gas column density, and surface gas injection density are successfully obtained using this approach. The gas-column pressure in the tubing is strongly influenced by the surface gas injection rate. By controlling the surface gas injection rate then the column-gas pressure in the tubing will be stable. The stable gas-column pressure leads to the stable oil production. This research is genuinely believed to be the first analytical approach of determining intermittent gas lift parameters. The results are give huge advantageous and applicable either for the educational as well as industrial purposes.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Analytical approach,Gas columns,Gas injection rate,Inflow performance relationships,Nodal analysis method,Numerical approaches,Surface injections,Tubing performance relationships[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Analytical approach,Gas column pressure,Gas injection rate,Intermittent gas lift[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.2118/176211-ms[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
