(2018-05-01)Space laundry is non-existent onboard the ISS. Astronauts are forced to wear the same clothing for up to 3-5 days. After the clothing becomes soiled, it is discarded in resupply cargo ships. The discardment of soiled ...
-
(2018-03-28)In this research we present a numerical substitute for laboratory experiments through simulating a core sample fully bounded by the wetting phase to represent cocurrent and countercurrent spontaneous imbibition (SI) ...
-
(2017-10-26)Unconventional reservoirs are getting an increase in attention in the oil and gas industry. This is because of the high energy demands from all over the world, which cannot be satisfied by conventional resources alone. ...
-
(2012-07-16)Carbonate reservoirs are heterogeneous; therefore, proper acid placement/diversion is required to make matrix acid treatments effective. Viscoelastic surfactants (VES) are used as diverting agents in carbonate matrix ...
-
(2017-08-10)Removing submicrometer-sized oil droplets from water is still one of the leading challenges in the separation of emulsions. In the oil and gas industry, emulsions are handled in one of two distinctive ways: the stabilization ...
-
(2022-04-13)This study investigates how the structure of surfactant molecules interacts with the crude oil/rock/brine system characteristic of unconventional liquid reservoirs. In most cases, the interaction results in the improvement ...
-
(2013-05-02)Injection of low-salinity water showed high potentials in improving oil recovery when compared to high-salinity water. However, the optimum water salinity and conditions are uncertain, due to the lack of understanding the ...
-
(2013-12-04)Aqueous fluids introduced by different stimulation treatments cause water blockage in the near-wellbore region of wells. This water blockage acts the same as formation damage when the well is put back on production. One ...
-
(2017-08-16)The objective of this study was to develop an understanding of the relative permeability of oil-water systems in fractures. Presently, two-phase flow behavior through propped and unpropped fractures is poorly understood, ...
-
(2013-02-26)Surfactant flooding in carbonate matrix acidizing treatment has been widely used for changing the wettability of the rock and to achieve low IFT values. Optimizing the type of surfactant and concentration for the specific ...
-
(2014-08-20)Steam-assisted gravity drainage (SAGD) is an in-situ bitumen extraction technique that significantly increases ultimate oil recovery from oil sand reservoirs. Because SAGD is one of the newest proven thermal oil recovery ...
-
(2015-12-14)Over the past fifty years, Improved Oil Recovery (IOR)/Enhanced Oil Recovery (EOR) technologies have been modified to include the effects of salinity of injected brine on oil recovery. Water-Alternating-Gas (WAG) is one ...
-
(2017-06-29)Improving oil recovery from unconventional liquid reservoirs (ULR) is a major challenge, and knowledge of recovery mechanisms and interaction of completion fluid additives with the rock is fundamental in tackling the ...
-
(2019-07-15)Enhanced Oil Recovery (EOR) has been a popular topic as of lately with numerous field cases showing a higher recovery is achievable with the addition of certain chemical additives. This EOR refers to any method of trying ...
