Specifying annual catch limits for artisanal fisheries, low economic value stocks, or bycatch species is problematic due to data limitations. Many empirical management procedures (MPs) have been developed that provide catch advice based on achieving a stable catch or a historical target (i.e., instead of maximum sustainable yield). However, a thorough comparison of derived yield streams between empirical MPs and stock assessment models has not been explored. We first evaluate trade-offs in conservation and yield metrics for data-limited approaches through management strategy evaluation (MSE) of seven data-rich reef fish species in the Gulf of Mexico. We then apply data-limited approaches for each species and compare how catch advice differs from current age-based assessment models. MSEs identified empirical MPs (e.g., using relative abundance) as a compromise between data requirements and the ability to consistently achieve management objectives (e.g., prevent overfishing). Catch advice differed greatly among data-limited approaches and current assessments, likely due to data inputs and assumptions. Adaptive MPs become clearly viable options that can achieve management objectives while incorporating auxiliary data beyond catch-only approaches.

Abstract Given the increased demands on the production of hydrocarbons and cost-effectiveness for the Operator's development wells, the industry is challenged to continually explore new technology and methodology to improve drilling performance and operational efficiency. In this paper, two recent case histories showcase the technology, drilling engineering, and real-time optimization that resulted in record drilling times. The wells are located on shallow water in the Gulf of Mexico, with numerous drilling challenges, which typically resulted in significant Non-Productive Time (NPT). Through close collaboration with the Operator, early planning with a clear understanding of offset wells challenges, well plan that minimize drilling in the Upper Cretaceous "Brecha" Formation were formulated. The well plan was also designed to reduce the risk of stuck pipe while meeting the requirements to penetrate the geological targets laterally to increase the area of contact in the reservoir section. This project encapsulates the successful application of the latest Push-the-Bit Rotary Steerable System (RSS) with borehole enlargement technology through a proven drilling engineering process to optimize the drilling bottomhole assembly, bit selection, drilling parameters, and real-time monitoring & optimization The records drilling times in the two case histories can be replicated and further improved. A list of lessons learned and recommendations for the future wells are discussed. These include the well trajectory planning, directional drilling BHA optimization, directional control plan, drilling parameters to optimize hole cleaning, and downhole shocks & vibrations management during drilling and underreaming operation to increase the drilling performance ultimately. Also, it includes a proposed drilling blueprint to continually push the limit of incremental drilling performance through the use of RSS with hydraulics drilling reamers through the Jurassic-age formations in shallow waters, Gulf of Mexico.

As oil exploration and production moves farther offshore, innovative technology is required to exploit energy resources in ever deeper waters. This paper covers two areas of deepwater production: offshore Brazil and the Gulf of Mexico. The types of wells and their capacity are described as well as the alternative platform designs, both fixed and semisubmersible, being used to recover both oil and gas from depths greater than 1500 ft. The paper outlines why these deepwater regions are of interest now and describes developments that are expected in the near future.

Abstract The characteristics of Pre-Salt carbonate reservoirs demand downhole chemical injection to prevent scale, asphaltene, and wax deposits, besides the need of H2S scavenger, and MEG, normally injected at Xmas tree (WCT). The poor performance of injection systems installed in Santos Basin, together with production risks associated to the lack of chemical injection, led the project team to re-evaluate design requirements, such as chemical products characteristics, production systems equipments, umbilicals, and chemical injection valves. In addition, umbilical failures are being observed in other deep-water fields, related to subsea control systems functions. This paper focuses on Company operational experience and lessons learned related to umbilicals and downhole chemical injection.


The rising expansion and diversification in the cybercrime arena have become difficult obstacles in order both to understand the extent of embedded risks and to define efficient policies of prevention for corporations, institutions, and agencies. The present study represents a comprehensive review of the origin, typologies, and developments of cybercrime and hacker subculture. This chapter confronts the issues by describing and discussing different criteria of classification in the field and by providing a broad list of definitions and an analysis of the cybercrime practices. A conceptual taxonomy of cybercrime is described as well. Common categories include the digital device is the target to commit the crime, the digital device is used as a tool to perpetrate the felony, or a digital device is an incidental condition to the execution of a crime. The authors complete their study by analyzing lessons learned and future actions that can be undertaken to tackle cybercrime and harden cybersecurity at all levels.

A climate change and health vulnerability and adaptation assessment was conducted in Dominica, a Caribbean small island developing state located in the Lesser Antilles. The assessment revealed that the country’s population is already experiencing many impacts on health and health systems from climate variability and change. Infectious diseases as well as food and waterborne diseases pose continued threats as climate change may exacerbate the related health risks. Threats to food security were also identified, with particular concern for food production systems. The findings of the assessment included near-term and long-term adaptation options that can inform actions of health sector decision-makers in addressing health vulnerabilities and building resilience to climate change. Key challenges include the need for enhanced financial and human resources to build awareness of key health risks and increase adaptive capacity. Other small island developing states interested in pursuing a vulnerability and adaptation assessment may find this assessment approach, key findings, analysis, and lessons learned useful.

ABSTRACT In May of 2003 a drilling riser break at a BP development well in 6015 feet (1875 m) of water in the Gulf of Mexico initiated a dialog between BP responders and NOAA/HAZMAT modelers about the potential consequences of a deep well blowout. Human health and safety issues were the key concern for BP responders, particularly those planning potential on water operations. Where might the gas surface? Would the natural gas (propane and methane) at the water's surface pose an explosion or asphyxiation hazard? Was there a potential for the gas bubbles to sink any of the response vessels? These discussions did not have as cut-and-dry answers as either BP or NOAA would have preferred. During the planning for BP's attempt to bring the well back into operation, the General NOAA Oil Modeling Environment (GNOME) with the Clarkson Deep Oil and Gas model (CDOG, Zheng et al 2003, Chen and Yapa 2003 and Yapa and Cheng 2004) were run. The data required for modeling a deep spill is more extensive then for a surface oil trajectory and was the subject of much discussion between BP responders and NOAA/HAZMAT. As a result, NOAA/HAZMAT created a data summary request sheet (Appendix 1) to guide the BP responders in what data was needed, and provided a point of discussion for implications of missing data.
