[00:00:01.180]Hello, I'm Kazi Albab Hussain, a PhD student
[00:00:04.160]in the department of Civil and Environmental Engineering
[00:00:06.960]at University of Nebraska Lincoln.
[00:00:09.290]I'm working with Professor Dr. Yusong Li.
[00:00:11.610]Today, I'm gonna talk about Nanoparticle Induced,
[00:00:14.110]Enhanced treated oil recovery
[00:00:16.260]and Effect of Nanoscale Surface, Roughness
[00:00:17.948]and Surface Composition
[00:00:19.620]on nanoparticular induced, enhanced oil recovery.
[00:00:23.880]For this project, I really appreciate the help
[00:00:26.410]from professor Dr. Mathias Schubert and Eva Schubert,
[00:00:30.400]and the other student Ufuk Kilic and Matthew Hilfiker.
[00:00:35.660]Throughout this presentation, I'll be discussing about
[00:00:38.680]what are the different types of oil recovery?
[00:00:41.983]What are the different types
[00:00:43.270]of conventional oil recovery methods?
[00:00:45.310]What are their disadvantage?
[00:00:46.720]And how nanoparticle can help overcome those challenges
[00:00:51.960]of this conventional oil recovery techniques,
[00:00:54.960]and how the presence of nanoscale surface, roughness
[00:00:59.320]and also the nanoscale surface composition
[00:01:02.110]would affect the nanoparticle induced, enhanced
[00:01:05.090]oil recovery mechanisms.
[00:01:07.650]There are primarily three types
[00:01:09.400]of enhanced oil recovery methods,
[00:01:11.100]primary recovery, secondary recovery,
[00:01:13.029]and enhance oil recovery.
[00:01:15.320]After a primary and secondary oil recovery,
[00:01:18.258]there is still 60 to 70% original oil remains in place.
[00:01:23.630]Throughout this presentation, I'll be turned 60 to 70% oil,
[00:01:27.500]which remains in place after primary
[00:01:29.530]and secondary recovery as residual oil.
[00:01:33.550]In order to recover those 60 to 70% of the oil,
[00:01:37.467]the enhanced oil recovery methods comes into play.
[00:01:41.410]The enhanced oil recovery methods
[00:01:43.320]involves the injection of fluid or thermal energy
[00:01:46.680]which interacts with the Rockwell systems
[00:01:49.120]and contributes to the enhancement of oil recovery.
[00:01:54.560]There are three types of conventional oil recovery methods
[00:01:57.540]Thermal methods, Chemical methods and Gas methods.
[00:02:00.448]Those methods has its disadvantage
[00:02:04.480]like high energy cost,
[00:02:06.900]and the Chemical methods decreases it's efficiency
[00:02:10.190]of other failure and the Gas methods
[00:02:12.480]causes viscous fingering.
[00:02:14.000]Also, the gravity override.
[00:02:16.980]How about when nanoparticle is used
[00:02:19.420]together with those conventional oil recovery methods.
[00:02:22.710]There's provides us some advantage,
[00:02:24.790]like introduces the interfacial tension,
[00:02:28.140]is change the wettability of the rock surface
[00:02:31.840]from the well wet to the water wet,
[00:02:33.440]and prevents the viscous fingering for example
[00:02:36.490]in this picture, we can see, when the free gas was used
[00:02:40.451]there was viscous fingering.
[00:02:43.200]However, when what it was used with nanoparticles,
[00:02:46.410]it improved his mobility
[00:02:48.340]and solved the problem of the viscous fingering.
[00:02:52.440]And when nanoparticular is used
[00:02:54.040]it provides additional 50% of enhancement
[00:02:57.753]in the oil recovery.
[00:02:59.830]And then in a particle contributes
[00:03:01.560]to the enhanced oil recovery
[00:03:03.240]by the following method mechanisms,
[00:03:05.210]like disjoining pressure, blocking the pore channels,
[00:03:10.390]preventing the asphaltene precipitation, or also
[00:03:12.990]changing the wettability of the rock surface.
[00:03:16.540]But the question is, when-which methods is coming into play?
[00:03:19.870]This is not clear in order to successfully
[00:03:23.270]apply those methods in the pedestal application.
[00:03:25.790]It is really important to understand,
[00:03:28.070]how this mechanisms is going to change
[00:03:31.530]due to the surface characteristics.
[00:03:34.870]So in order to do that, the objective
[00:03:36.980]of our project is to study the effect
[00:03:40.650]of nanoscale surface, roughness, and surface composition
[00:03:43.760]on the enhance oil recovery mechanisms.
[00:03:47.720]In order to do that, we have synthesized,
[00:03:50.320]we have fabricated that S.I. slandered columnar thin-film
[00:03:55.770]using the glancing angle deposition technique.
[00:03:58.860]After, synthesizing Si-SCTF structure,
[00:04:02.830]We have fabricated those structure using
[00:04:07.030]Atomic layer deposition technique either using Aluminium
[00:04:11.560]or SiO2 coating.
[00:04:14.920]So, after fabricating those slandered columnar
[00:04:19.060]thin-film we have characterized those thin-film
[00:04:21.610]using the Ellipsometric technique or SEM imaging.
[00:04:27.170]Here in this picture,
[00:04:28.060]we can see a SEM imaging of a SCTF structure.
[00:04:34.030]Once those structure are fabricated
[00:04:36.010]then we have double-up the the residual oil.
[00:04:38.260]In order to do that,
[00:04:39.340]we have flowed n-Decane through the QCMD cell,
[00:04:44.330]then the DI water was flowed for a long time,
[00:04:47.220]approximately one and half hour then whatever developed,
[00:04:52.860]whatever the oil percentage has remained
[00:04:54.580]on the QCMD sensor is stand as residual oil.
[00:04:58.120]So afterwards we have characterized the QCMD sensor
[00:05:02.080]using the Ellipsometric technique and we found
[00:05:05.410]that approximately 10% of the oil remained in place.
[00:05:09.570]So we can see, like, here is the word friction.
[00:05:12.400]And few of the word friction is occupied
[00:05:15.500]with those oil percentage.
[00:05:19.687]Then the nanoparticle was prepared
[00:05:22.810]for the enhanced oil recovery application.
[00:05:24.717]And it was also characterized using
[00:05:26.850]the ZetaPALS meter and found that it has a 15 nanometer
[00:05:33.170]of hydrodynamic diameter and the general potential
[00:05:35.950]is minus 15 minimum miniVol.
[00:05:40.290]There for the oil recovery application,
[00:05:42.810]Then, the, after the residual oil development
[00:05:46.290]the 10 PPM titanium dioxide nanoparticle solution
[00:05:49.570]was flowed, then it was characterized externally
[00:05:52.860]using the Ellipsometric technique.
[00:05:55.800]And we found that after the Ellipsometric,
[00:06:01.960]when the nanoparticle was used originally there was 10%
[00:06:08.690]oil in place after the water flooding.
[00:06:12.400]Harbor, when we have a flooded it
[00:06:15.310]with the titanium oxide nanoparticles
[00:06:18.300]now only 6% of the original oil remain in place.
[00:06:21.850]Which means the application of the nanoparticle
[00:06:25.540]increased the oil recovery by around 4%.
[00:06:32.210]And we can see that some titanium oxide
[00:06:35.640]nanoparticle is deposited on the surface.
[00:06:39.840]Then we have change the surface
[00:06:42.770]from the aluminum coating to Sio2 or to coating.
[00:06:47.060]So, when we have changed the coating,
[00:06:48.980]we still see the use of the nanoparticle
[00:06:52.580]has enhanced that oil recovery per bar.
[00:06:57.760]At this time, we did not see any nanoparticle deposition.
[00:07:02.480]Which means that the change of the structure properties
[00:07:06.470]has changed the principle mechanism
[00:07:11.740]of nanoparticle induced enhanced oil recovery.
[00:07:16.937]So in conclusion, we can say,
[00:07:20.810]use of nanoparticle contributed
[00:07:22.700]to the enhanced oil recovery and the mechanism
[00:07:26.960]of enhancements oil recovery is largely dependent
[00:07:29.680]on the surface property of the pores media.
[00:07:34.220]When Al2o3-aluminium is present the nanoparticle
[00:07:40.880]could be attached, absorb to the surface
[00:07:46.420]and in the presence of silicon dioxide
[00:07:49.140]the nanoparticle does not absorb to the surface.
[00:07:52.870]Instead, the disjoining pressure watch
[00:07:55.830]as the principle mechanism of the oil recovery
[00:07:59.200]I thank the support from the American Chemical Society
[00:08:03.190]for supporting this project.
[00:08:05.590]Thank you.
