Supercritical Co2 Foam Enhanced Oil Recovery: From Mechanistic Model Fit To Lab Experiments To Field-Scale Evaluation, Mohammad Izadi Sep 2019

Supercritical Co2 Foam Enhanced Oil Recovery: From Mechanistic Model Fit To Lab Experiments To Field-Scale Evaluation, Mohammad Izadi

LSU Doctoral Dissertations

This study investigates how a mechanistic foam modeling approach based on bubble population balance is applied to a series of laboratory experimental data of a supercritical CO2 foam in reservoir conditions to extract model parameters (topic 1). The model with model parameters determined from the fit is then used to estimate how far fine-textured strong foam can propagate into the reservoir, before turning into coarse-textured weak foam and before being segregated by gravity (topic 2). With the help of mechanistic model, a possible range of gas mobility for supercritical CO2 foam is calculated and the resulting gas-phase mobility …


Investigation Of Flow Mechanisms In Gas-Assisted Gravity Drainage Process, Iskandar Dzulkarnain Aug 2018

Investigation Of Flow Mechanisms In Gas-Assisted Gravity Drainage Process, Iskandar Dzulkarnain

LSU Doctoral Dissertations

In this study we investigate displacement mechanism for oil recovered using Gas- Assisted Gravity Drainage (GAGD) method. For a typical oil recovery under gravity drainage, the recovery profile can be characterized by an initial bulk flow which occurs rapidly and a later film flow that extends for a longer duration. It is the latter period where film spreading, the ability of oil to spread above water in the presence of gas, is identified as the displacement mechanism responsible for recovering the remaining oil in gravity drainage process. Literature survey indicates that mathematical models for gravity drainage do not account for …

Development Of Single-Well Gas Assisted Gravity Drainage Process For Enhanced Oil Recovery, Bikash Deep Saikia Jan 2016

Development Of Single-Well Gas Assisted Gravity Drainage Process For Enhanced Oil Recovery, Bikash Deep Saikia

LSU Doctoral Dissertations

EOR application in prolific deepwater Gulf of Mexico (DGOM) reservoirs has remained a challenge. Exorbitant well cost (>200M$) precludes having extensive injection patterns and very characteristics of the reservoirs themselves are partly to blame for negligible EOR activity in DGOM. We have been able to develop and demonstrate a novel design in the form of Single Well – Gas Assisted Gravity Drainage (SW-GAGD) process, which is potentially cost effective, at the same time ensuring very high oil recoveries. In this design, a single well acts as an injector as well as a producer, thereby minimizing well cost. The efficacy …
