ABSTRACT We examine whether chief executive officer compensation aligned with stakeholders' interests is associated enhanced corporate carbon transparency. Using an international sample obtained from the CDP, we find that transparency—as measured by both propensity to voluntarily disclose information and quality comprehensiveness of disclosure—is greater when managers' contracts are better stakeholder interests. Further analyses indicate this positive relationship stronger in countries or...
Summary To address the significant scaling challenges within near-wellbore formation of ultradeep natural gas reservoirs characterized by high temperature and salinity, we developed a dynamic prediction model. This model is specifically designed for in gas-water two-phase seepage fractured-matrix dual-porosity reservoirs. It accounts concentration effects resulting from evaporation water on ions. Our discretely solved using finite volume method. We also conducted on-site simulations wells,...
ABSTRACT We analyze the relationship between financial transparency and carbon based on ethical opportunistic perspectives. Our sample comprises 10,341 firm-year observations from firms in 55 countries or regions CDP (previously Carbon Disclosure Project) during period 2003–2015. measure both managerial propensity to publicly disclose information level comprehensiveness of voluntary disclosure. operationalize firms' earnings management (EM). find that our proxies are negatively associated...
Using acrylic acid advanced ester and styrene as raw materials, the long-chain polyester polymer, polyacrylic ester-styrene pour point depressant (P-PPD), was synthesized by molecular design, its structure characterized infrared spectroscopy nuclear magnetic resonance. In addition, this study experimentally investigated effect of P-PPD on phase equilibrium induction time natural gas hydrate inhibitors in deionized water (DW) crude oil/water (O/W) systems, respectively. Polyvinylpyrrolidone...
This study empirically investigates the role of political connections in corporate environmental spending. It employs a sample listed Chinese firms from polluting industries within 2010–2013 period. Our empirical results show that having politicians as directors reduces magnitude discharge fees. We also find such reductions are more pronounced with higher ratio politically connected (i.e., privately controlled). negative relationship is robust to various model specifications (e.g., after...
the interrelations among environmental performance, disclosure and corporate value, are basic issues of firm behavior. There different arguments in prior literatures. Based on investigation 145 listed chemical firms China, we obtain results (1) disclosures level is significantly associated with performance; (2) can not impact value significantly.
Acidic fracturing flowback fluid (AFFF) has the characteristics of low pH value, high chemical oxygen demand (COD), corrosiveness and complex components. Surface discharge without treatment may contaminate environment. However, wastewater after centralized transportation potential safety risks requires costs. In this study, we confirmed that calcium magnesium could affect cross-linking property prepared by fluid, conducted a three-step process, two-stage filtration, precipitation,...
Chinese merchant groups are commercial organizations that have developed over thousands of years. Given the importance private firms to China’s sustainable development, this study investigates impact traditional concept on corporate social responsibility (CSR) performance and cost debt, using listed during 2008–2020. We measure group culture based company’s geographic location. Ordinary least squares regression models used test hypotheses. According results, CSR from five is better than...
With increasing emphasis being placed on corporate social responsibility, the number of companies furnishing responsibility (CSR) reports is increasing. This study investigates impact abnormal positive tone in CSR analysts’ earnings forecast bias. The textual analysis Chinese listed between 2006 and 2016 reveals that an significantly positively relates to optimistic bias forecasts. effect pronounced among with poor financial transparency those operating regions where culture...
Abstract Gas injection has become an important means of enhancing oil recovery (EOR) in clastic reservoirs, the Donghe Oilfield, Tarim, been undergoing gas to enhanced recovery. During injection, dynamic justification was most severe challenges, which needed monitor pressure profile, temperature profile and profile. Therefore, monitoring becoming part drive reservoirs. Oilfield characterized by ultra-deep (>6000m), high (>140°C) content carbon dioxide, conventional manometer...
DeepContact is a deep learning software for high-throughput quantification of membrane contact site (MCS) in 2D electron microscopy images. This protocol will guide users through incorporating available models Amira's artificial intelligence module, thereby allowing invoking functions organelle segmentation and quantifying MCS with user-friendly graphical user interface Amira software. For complete details on the use execution this protocol, please refer to Liu et al. (2022).
In recent years, the high temperature and pressure gas wells production in Kuqa mountain front zone were severely restricted due to blockage of wellbore, which affected efficient development field group front. The Dina Keshen blocks main fields wellbore problem was more severe. mainly concentrated Keshen2 block. More than 50% had that problem, leaded millions square meters loss compared with full production. As for field, severer 80% problems, resulted reducing by half, even shutting down...
Abstract Dabei and Dina 2 gas fields located in Tarim Oilfield are HTHP high production condensate fields. The formation temperature is 136°C, the pressure 105MPa, of single well 40×104m3/d~100×104m3/d, 35t/d~86t/d. After started production, oil continues to fluctuate decline due wellbore plugging. By 2019, more than 80% wells have plugging problem, some reduced over 50%, a few even shut in, normal seriously affected. In field, organic substances obtained wellhead nearby pipes during passing...
This paper develops a game model to depict the process of determining trading price and volume at equilibrium Chinese carbon emission allowance market. Assuming that cost for reduction is normally distributed random variable, enterprises are risk-neutral, total quantity emissions allowances whole market given, exogenous linear function, shows CO2 both affected by magnitude variance in costs borne companies targets government. More specifically, ratio between variances associated with speed...
Surfactant-grafted Polyacrylamide (S-PAM) serves as a novel oil displacement agent in oilfield. Its toxicity and the impact on occupational safety are unclear. The analysis composition chemical structure of S-PAM shows that due to its instability harmful ammonia gas may be generated during operation or high temperature. evaluation were analyzed, suggestions protection proposed. It can provide safe healthy working environment for operators with enormous social economic benefits.
