Paper presented at the Carbon Management Technology Conference, July 15–18, 2019
Paper Number: CMTC-553897-MS
... Abstract Deep saline aquifer is deemed as an effective and promising site for carbon sequestration. A geological storage site must be operated safely; however, CO 2 may leak through several pathways, such as fractures, faults and/or improperly plugged wells. This study presents a new...

... impact on oil recovery, especially as the injection cycles progressed. The thermodynamic conditions were also found to impact the core integrity greatly, with some cores breaking at some conditions, and the natural fractures being stimulated as well. This research can help illustrate the impact...

Paper presented at the Carbon Management Technology Conference, July 17–20, 2017
Paper Number: CMTC-484390-MS
... Abstract The application of horizontal well drilling coupled with the multistage fracturing technology enables commercial development of shale gas formations, which launches the energy revolution from conventional resources to unconventional resources. With the progress of understanding...

Paper Number: CMTC-485111-MS
... that the intensity of natural fractures (the number of natural fractures per length unit in each direction, I-direction, J direction, and K direction) and the conductivity of oil pathways (the average conductivity for the entire oil molecules path, from its storage (matrix) to the wellbore) are the two main factors...

Paper Number: CMTC-485175-MS
... approaches have been integrated to investigate the feasibility of three different miscible-gases which are CO 2 , lean gases, and rich gases. Firstly, numerical simulation methods of compositional models have been incorporated with Local Grid Refinement (LGR) of hydraulic fractures to mimic the performance...

... sequestration sites. However, these analytical techniques have ignored the effect of fracture occurrences, which are important to the carbon sequestration in shale formation. In this paper, numerical simulation technology is applied to model different complex hydraulic fracture occurrences and evaluate the CO...

Paper presented at the Carbon Management Technology Conference, July 17–20, 2017
Paper Number: CMTC-486243-MS
... Abstract After implications of hydraulic fracturing operations, the commercial production of tight formations and shale plays were successfully achieved in past decades. Due to the rapid decline rate after primary depletion of fractured reservoirs, extracting the remaining liquid hydrocarbon...

Paper Number: CMTC-486335-MS
... Abstract The San Andres is a well-known dolomitic enhanced oil recovery target with low matrix permeability in the area of interest (Yoakum County, TX). A reservoir simulation study was undertaken to investigate the feasibility of using horizontal multi-fractured wells in low permeability...

... performance in field scale. This study found that the porosity and permeability of natural fractures in shale reservoirs are significantly changed with production time, which in turn, led to a clear gap between CO 2 performances in lab-conditions versus to what happened in field pilots. As a result...

Paper presented at the Carbon Management Technology Conference, February 7–9, 2012
Paper Number: CMTC-151480-MS
... Abstract CO2 sequestration in mature oil and gas reservoirs is attractive due to the possible cost offsets from enhanced oil recovery (EOR). In this work we develop a 3D reservoir model and fluid flow simulation of the fractured Tensleep Formation using geomechanical constraints in advance...
