“…The flow back of the synthetic brine in LSSE is to mimic the flow of production fluid out of the reservoir formation. During this process, the production fluid would be in contact with the retained inhibitor and gradually release the retained inhibitor back into aqueous production fluid for the scale control (an inhibitor return process) [ 13 , 14 , 15 , 16 ]. An inhibitor return curve can be established by plotting the effluent inhibitor concentration versus the number of PVs of the brine returned during an LSSE.…”

“…Although squeeze treatment has been the standard operation in the oilfield to control scale threats downhole and in the well, there are a number of drawbacks associated with conventional squeeze treatment. One of the most pronounced drawbacks is that often more than one-third of the delivered inhibitor will flow out of the formation, together with the production fluid, during the very early stage of inhibitor return due to a poor attachment of inhibitor on the surfaces of formation materials, leading to a considerable waste of inhibitor and hence a reduced squeeze lifetime [ 9 , 14 , 16 ]. To address the shortcomings of conventional squeeze treatment, scale inhibitor colloidal materials have been prepared as an alternative to the conventional chemical inhibitor to be deployed during squeeze treatment.…”

Mineral scale refers to the hard crystalline inorganic solid deposit from the water phase. Although scale formation is very common in the natural environment, deposited scale particles can seriously threaten the integrity and safety of various industries, particularly oilfield productions. Scale deposition is one of the three most serious water-related production chemistry threats in the petroleum industry. The most commonly adopted engineering approach to control the scale threat is chemical inhibition by applying scale inhibitor chemicals. Aminophosphonates and polymeric inhibitors are the two major groups of scale inhibitors. To address the drawbacks of conventional inhibitors, scale inhibitor colloidal materials have been prepared as an alternative delivery vehicle of inhibitors for scale control. Quite a few studies have reported on the laboratory synthesis and testing of scale inhibitor colloidal materials composed mainly of pre-precipitated metal-aminophosphonate solids. However, limited research has been conducted on the preparation of polymeric inhibitor-based colloidal materials. This study reports the synthesis approach and laboratory testing of novel polystyrene sulfonate (PSS) based inhibitor colloidal material. PSS was selected in this study due to its high thermal stability and calcium tolerance with no phosphorus in its molecule. Both precipitation and surfactant surface modification methods were employed to prepare a barium-PSS colloidal inhibitor (BaPCI) material with an average diameter of several hundred nanometers. Experimental results indicate that the prepared BaPCI material has a decent migration capacity in the formation medium, and this material is superior to the conventional PSS inhibitor in terms of inhibitor return performance. The prepared novel BaPCI material has a great potential to be adopted for field scale control where environmentally friendly, thermal stable, and/or calcium tolerating requirements should be satisfied. This study further expands and promotes our capacity to fabricate and utilize functional colloidal materials for mineral scale control.

“…3 and Table 2, we can conclude that: (1) NSCA outperformed SCA for all test functions, except for F3. (2) In comparison to other algorithms, NSCA exhibited better performance on most functions, especially on composite functions, where it achieved the best results overall. (3) NSCA achieved more "+" symbols than "=" and "-" symbols, indicating that it significantly outperformed the other algorithms.…”

“…Global optimization problems are common in real-world applications, and finding effective methods to solve them is a popular research topic. Traditional methods, like the gradient descent [1] and Newton's methods [2], have been used extensively to solve various optimization problems. However, these techniques may not be effective for complex objective functions that are discontinuous, non-differentiable, multimodal, or high-dimensional.…”

The sine cosine algorithm (SCA) is a simple and efficient optimization algorithm that utilizes sine and cosine trigonometric functions to update solutions. The SCA may suffer from premature convergence to local optima due to its insufficient utilization of population information and lack of mechanism to escape from local optima. Therefore, this study proposes an improved version of the SCA called the novel sine cosine algorithm (NSCA). NSCA incorporates a new solution update equation, a greedy selection mechanism, and a disturbance mechanism to improve population diversity and prevent search stagnation. Experimental results on the Congress on Evolutionary Computation (CEC) 2017 benchmark function set and six point cloud registration problems demonstrate the effectiveness and robustness of NSCA compared to other algorithms.

The evolution of logistics operations has been viewed from different perspectives, starting with its initially heuristic approach and transforming into a set of advanced regulations and practices. The main objective of the research is to analyze the most influential publications, authors, institutions, and nations in the field of logistics operations, explore current research trends, and analyze the knowledge evolution in this area. To achieve this, a systematic literature review of Scopus data from 2002 to 2022 was conducted, with a focus on organizing, observing, and systematizing data. The results revealed that research on Cross-Docking, order picking, and warehouse planning emphasizes the need to optimize logistic processes to enhance efficiency, reduce costs, and maintain competitiveness in an ever-changing business environment. These studies reflect the ongoing quest for effective solutions to address current logistical challenges and underscore the importance of innovation and optimization in supply chain and logistics management.
