Lactate as a Regulator of Cancer Inflammation and Immunity
Authors: Santos Nuno , Pereira-Nunes Andreia , Baltazar Fátima , Granja Sara 
Published: October 2019

Abstract
Resistance to anti-cancer therapies is a consequence of adaptation of cancer cells but also of maladaptation of tumor-infiltrating immune cells. The opposing roles acquired by the immune system have to be faced in order to fight tumor growth and therapy resistance. Effector immune cells are recruited and activated but they are blocked by the strong immunosuppressive nature of the tumor microenvironment (TME). Immune evasion and deregulation of energy metabolism are two hallmarks of cancer that may be functionally linked. Malignant cells which present a high glycolytic phenotype, besides creating metabolic demanding environments that encroach on the function of tumor-infiltrating immune cells, also release immunosuppressive metabolites and by-products, such as lactate, forming a metabolic symbiosis with immune cells. This acidic TME has a strong impact in the profile of tumor-infiltrating immune cells, being instrumental for immunosuppression. Therefore, in this review, we focus on key molecular mechanisms by which lactate metabolically modulates immune cell response during tumor development and progression.
Criminalization as a main threat to economic security

Published: October 2019

In modern Russia, the criminalization of the economy has become one of the most acute problems, a nationwide negative factor that undermines the authority of the authorities, destroys the foundations of statehood, and, as a result, creates a threat to the country's economic security. These circumstances dictate the need to quickly make optimal decisions that can protect the national economy from the negative effects of an illegal and criminal economy, as well as corruption as the basis of the shadow economy of Russia. Today we can say that the economic foundations of corruption, organized crime and terrorism are a kind of an independent sector of the economy. Corruption is beginning to seriously affect the decline in economic growth, the decline in the potential of civil society institutions, the violation of human rights, and other negative effects on the legal system. To achieve the goals, criminal structures use all means at their disposal: influence through government bodies and at the diplomatic level, special services, organized criminal communities, terrorist organizations, banking structures, non-profit and non-governmental organizations, subjects of criminal and shadow economy, etc. Analysis of market relations, the Russian economy gives the right to understand that the national economy in the position in which it is located cannot get out of the state of criminalization without reviewing and forming new relationship mechanisms.

Published: October 2019

Abstract
The gas influxes occur frequently during the exploration in the South China Sea, which can pose severe risks to well control strategies. The traditional detection method is to analyze the mud-log of mud tanks, which is slow and there is always a time-lag between the gas influxes occurrence time and the influxes detection time. In this work, a methodology is proposed that allows for real-time gas influxes detection using artificial intelligence and data analytics.
To develop the methodology, mud-log (12 parameters) are collected for 208 influxes incidents for 62 drilled wells. Data analysis through artificial neural network is carried out to develop gas influxes warning system model. Then, a new comprehensive method using mud-log, is proposed for real-time gas influxes detection.
This is one of the first attempts for real time gas influxes detection utilizing data analysis of mud logging and artificial intelligence. This methodology is successfully applied to gas field in South China Sea with accuracies up to 95% achieved.

Published: October 2019

Abstract
This paper aims to highlight the benefits of using selective perforation as a method of risk reduction and optimization during perforating thin separated oil-bearing intervals going through selection criteria, job design, economic evaluation and precautions during the operation.
During the design of four perforation jobs in a campaign using the conventional through tubing perforation (TTP) technique, it was noticed that the number of runs were too much with consequent high intervention risk, thus alternatives were evaluated to mainly reduce intervention risk with a smart, reliable, cost effective and simple perforation technique within the pre-determined operation time frame. The other options included alternative deployment methods such as coiled tubing (CTU) perforation, extended reached perforation (ERP) and selective perforation techniques. A comparison between options has been made based on the following criteria: availability, simplicity, reliability, intervention risk and feasibility.
As a result of proper filtration and comparison between all different options, the selective perforation using addressable switches was selected to be the optimum solution for this case based on the comparison criteria mentioned above. Going through the design phase, multible loading sheets for guns laydown have been generated and optimized to reach the simplest operational procedures and minimum number of runs. Then, workshops have been made for engineers in both office and field to be familiar with the operation to reduce operational risks and consolidate the operational procedures. The design of service for the whole job including the final operational procedures, risk assessment and gun loading sheets was finalized and distributed to all disciplines to assure alignment during the operation. During job execution, operation has been followed step by step using single point of accountability (SPA) to accelerate and align decision making and plan modification during operational issues. Finally, a post job evaluation has been made to document the whole procedures of design and execution and the lessons learned during the operations. A final comparison between conventional and actual selective perforation job showed the reduction in number of runs and thus time and intervention risk by 33%. In addition, the incremental increase in cost was completely covered by the time saving from the utilization of supporting vessels (Rig & boats).
The major aim of this paper is to clarify in a step-by-step style the method of evaluating the well for addressable switches technique and how to properly prepare the people for the job and the design of service till execution followed by post job evaluation.
Use of Carbonated Slickwater for Fracturing Unconventional Formations

Published: October 2019

Abstract
Fracturing with slickwater has been widely adopted over the past couple of decades in the development of shale and tight formations. Horizontal wells utilize 0.5 to 1 million gallons of water per stage for upward of 40 stages per well. Reducing water usage in hydraulic fracturing treatments is of global interest due to various motives including water scarcity, government regulations, environmental concerns, and optimizing flowback and well productivity. The objective of this paper is to explore foamed slickwater as a potential alternative fluid to slickwater.
A circulating-loop foam rheometer having a helically coiled, 10 ft long tube was utilized in this study to compare the rheological behavior of slickwater and CO2-foamed slickwater at varying foam qualities. The rheological behavior of water and linear gel at varying foam qualities was also investigated. These fluids were tested under a wide range of conditions including pressures up to 5000 psi, temperatures up to 300°F, and shear rates up to 1500 1/s. In addition, SEM imaging and geomechanical testing on tight carbonate rock specimens were performed to investigate the effect of slickwater and supercritical CO2 on rock texture and tensile strength.
A growing body of literature has recently proven that injection of supercritical CO2 generates much more complex fracture network compared to slickwater-induced fractures in unconventional formations. CO2 alone has poor proppant carrying capacity. This paper presents a novel demonstration of carbonated slickwater as a potential fluid that maintains good proppant carrying capacity while achieving less fresh water consumption, faster and efficient flowback recovery, improved hydrocarbon recovery due to CO2 miscibility with reservoir fluids, and potentially a more extensive stimulated reservoir volume.

Abstract
Water flooding is an established method to increase oil production. In this research, we present a novel approach that uses data mining techniques on the operations data on a complex mature oil field located in the Gulf of Suez, currently being water flooded. We show how such methods help improve reservoir characterization for this specific field is particularly challenging because of its geological complexity and field performance.
The continuous recording of production and injection data presents a new opportunity to apply analytical approaches to reservoir management. Such approaches provide an alternative to the traditional history-match model update and prediction that is not only time-consuming but also carry forwards all subsurface uncertainties.
A combination of qualitative (cross-correlation analysis) and quantitative analysis (capacitance resistance model) is used to obtain an overall waterflood injection strategy for this Gulf of Suez field. In this manuscript, we focus on the analysis obtained from cross-correlation analysis. The presented analysis helps identify connectivity between wells in the reservoir during waterflood. The method presented is also adapted to specific characteristics of this field - water drive production in this model.
We present evidence of how salinity data can be used to further justify the linkages between the different wells obtained from the cross-correlation analysis. We also show comparison between results from this analytical technique and the streamline approach. This comparison with salinity and streamlines helps benchmark the model results especially in cases where such secondary data (salinity/streamlines) are not available. The results presented in this research can be adapted to any waterflooded field to optimize recovery at frequent intervals, where injection and production data is continuously available.

Abstract
ADNOC Offshore successfully revamped the field development plan of one of its reservoir in view of the newly acquired data during initial production phase from 5-Spot pattern drive to Semi-peripheral water injection strategy to ensure delay in water breakthrough and improved sweep efficiency. At the first stage, multi-disciplinary subsurface study was conducted utilizing and carefully analyzing all the available data. This lead to the development of the new model that was able to replicate the field current behavior.
Study of the several development strategies helped to analyze field behavior with different development schemes. The change in the development strategy from 5-Spot to Semi-peripheral resulted in an increase of plateau length for four years with an increase in recovery of 6% at economic cut-off limit.
Due to high productivity of the reservoir, wells were able to produce without any pressure support contrary to initially predicted performance that lead to the reduction in the water injectors and additional oil producers were incorporated in the development plan that would drain the reservoir more efficiently supported by gas lift. As part of further optimization, horizontal injectors were converted to slanted vertical injectors equipped with inflow control valves that provided full control and selectivity of the injected volume that would provide production assurance in such a high heterogeneous and differentially depleted reservoir. To support this change pilot test was performed that proved successful without jeopardizing the injectivity of the reservoir compared to horizontal well.
Implementation of the devised project is in progress that marks the importance of the initial production behavior of the field that could lead to a different development strategy. This project is unique in a sense that with all the additional constraints of surface limitations particularly in the offshore environment, this project is on its path of successful completion.
Impacts of Hydrogen Embrittlement on Oil and Gas Wells: Theories behind Premature Failures
Authors: Shadravan Arash , Amani Mahmood 
Published: October 2019

Abstract
Unleashing oil and gas resources would be greatly benefited with better understanding of the mechanisms behind hydrogen embrittlement. Carbon steel is the cost-effective materials of choice for pipelines and casings for sour service in the oil and gas industry. Hydrogen embrittlement weakens the interatomic bonds between grains of steel casing or offshore tools and causes premature failures. This phenomenon could pose a risk to the sustainability of the oil and gas projects.
Application of high strength steels has been an evolving field of research in the oil and gas industry. The utilization of high strength steels in increasingly more harsh environments has promoted manufacturing of new generations of highly ductile high-strength steels. Oil and gas wells could have hydrogen sulfide and therefore hydrogen embrittlement could be triggered. Emergent intricacy in designing downhole tools safely along with requirements to assure stiffness with less wall thickness has increased the use of high strength steels. Complex Phase steels were born once researchers discovered the benefits of partially replacing martensite by bainite. The diffusion of hydrogen through various types of materials have been a prime interest of engineers and scientists in miscellaneous fields. It is well known that when atomic hydrogen diffuses into steels with various microstructures, it could lead to hydrogen embrittlement, a phenomenon which its underlying mechanisms are yet to be precisely explained.
The purpose of this paper is to elucidate how hydrogen diffusion yields to hydrogen embrittlement. The mechanisms of hydrogen trapping, types of traps and the effects of lattice defects on hydrogen diffusion in addition to the classical hydrogen embrittlement theories are discussed in detail. Hydrogen diffusion in austenite, ferrite and cementite were compared and it was shown how thermal desorption analysis and permeation could determine a percolating threshold in preventing the passageway of hydrogen.

Management of Sustained Casing Pressure in Offshore Gas Wells by a Novel Casing-Surface Design that Suppress Gas Migration at the Casing-Cement Interface
Authors: Mwang'ande Alex William , Liao Hualin , Zeng Long 
Published: October 2019

Abstract
Sustained Casing Pressures (SCP) is still a serious problem that challenges the offshore producing gas wells. Despite existence of the many methods to mitigate it, SCP is still bringing severe health, safety and environmental (HSE) concerns necessitating the need for new methods. This article brings a new method of mitigating SCP caused by micro-annulus in offshore gas wells by designing a novel casing surface that will increase the length of casing-cement interface (CCI) for the same planned cement column length and thereby suppressing fluid migration through the CCI. Two new casing-surface designs were invented and tested by inputting the field data from offshore gas well X in conjunction with an existing SCP prediction model to verify the validity of the new method. The new developed method was found to have a great potential of controlling SCP and improve the production life time of the offshore gas wells by suppressing gas migration through micro-annulus.
