The aggregation behavior and thickening mechanism of both molecular categories is analyzed by SEM intuitively. Emulsification performances are investigated by analyzing the kinetic stability...

... used as a water-shutoff treatment in production wells when conventional solutions such as mechanical isolations are difficult to perform. Although this property has been well documented by different investigators, the performance of DPR treatments in field applications has varied between success...

... to unit cost. Although industry has been deploying this technology on a more widespread basis recently, they have not been as focused on the underlying mechanisms, physics and controlling parameters which ultimately govern the success of the stimulation event. This paper will present a comprehensive...

... During the last decade, the number of sour gas wells which have problems of iron sulfide deposition was increased. Great efforts have been made to understand the mechanisms and mitigation strategies of iron sulfide deposition in downhole tubulars. Corrosion and scale monitoring has played a key...

... used two very different driving mechanisms for the fluid displacement: centrifuge and flow-through. The data showed that carbonate and clastic rocks behaved differently over a wide range of flow mechanisms and water saturations, proving that mineralogy plays a crucial role in the fluid displacement...

... and understand the responsible mechanisms at scales ranging from nano-scale to field scale. The ionic formulation of the injected brine affects dramatically the crude oil/brine/rock interfaces, altering rock wettability and improving oil recovery efficiency. In this experimental work, a mechanistic study...

... Abstract Recently, we proposed a chemical mechanism for the role of clay in sandstone during low salinity water (LS water) flooding using acetate to simulate the oil-bound carboxylic acids with the reservoir ( Al-Saedi and Brady 2018 ). In this study, we propose to quantify the control...

... Abstract This paper describes a new approach to evaluating the effectiveness of the rotary steerable system (RSS) steering mechanism on wellbore tortuosity in horizontal wells. Wellbore tortuosity in drilling applications is defined as any unwanted deviation from the planned well trajectory...

... to failure. The problems of well cementing still persists despite advancements in technological development of cement and concrete materials. Moreover, changes in temperature and pressure during the life cycle of the well can give rise to several mechanisms of failure that could pose threat to the set cement...

... ). However, despite the success of these methods in inhibiting corrosion by HCl, it would be unwise to assume that the same methods can be applied with similar success to inhibit corrosion by chelating agents. Understanding the degree and mechanism of corrosion associated with the use of chelating agents...

... ( Hoffman et al., 2016 ). One of the main reasons might be due to the wrong prediction for CO2 diffusion mechanism in these types of reservoirs. A detailed study for determining the level of CO2 diffusivitity in the real field conditions have been conducted in this work. Identification the CO2 difffusivity...

... On the other hand, antiplasticization is another relevant phenomenon that affects long term performance of membrane gas searation process. It is commonly used to refer to the mechanism of membrane performance degradation in the presence of aggressive feed streams ( Lee, Madden, and Koros 2010...

..., these analytical techniques have ignored the capillary trapping mechanism, which is important to the carbon sequestration in aquifers. In this paper, a new analytical method to evaluate the saturation profile and CO 2 trapped quantity was derived. First, the fractional theory (Buckley–Leverett type model...

... Abstract Gas transport in extremely low-permeability shale formations is a multi-mechanisms-coupling process that includes gas adsorption-desorption, Knudsen diffusion, and slip flow. Incorporating these mechanisms into a unified mathematical model is crucial to obtain a more accurate shale gas...
