... Abstract Chevron has applied an increasingly robust approach to wellbore geohazards assessment over the Tahiti Field life. We discuss here how hazards assessment has evolved over nearly 2 decades. The last ~5 years we have applied a standardized approach to identify conditions of concern...

...), which requires toxicological data for hazard assessment. FIFRA is administered by the EPA, which has several situation-dependent methods of ecological risk assessment.2 While FIFRA establishes whether a certain biocide can be used and at what concentration it can be used in a certain application...

Introduction Classical risk management includes three main phases: 1) a hazard assessment including a hazard analysis (hazard characterization and frequency analysis...

... of the measured swabbing pressures. A procedure for shallow gas hazard assessment is proposed. This procedure serves as input for risk management for riser- less drilling and associated logging, sampling and testing. Introduction Shallow gas in marine soils is a hazard for open-hole or riser-less borehole...

... to hazard assessment in the Gulf of Mexico. Introduction Fault-related hazard in the Gulf of Mexico is related to movement on both deep-seated crustal faults, and shallow gravity driven growth faults. The hazard presented by deep faults is primarily the effects of shaking caused by strong ground motion...

... also have been used to evaluate the hazard posed by both intrusive and extrusive volcanic events [3], [4], [5]. More recently, probabilisitic methodologies, which were developed in conjuction with seismic hazard assessments for the proposed nuclear waste repository at Yucca Mountain, Nevada [6], [7...

... investigation then developed a proposal to incorporate new technology such as high-resolution 3D seismic data reprocessed for shallow hazards assessment. The primary intent of their suggestions was to cover new deepwater geohazard challenges, such as shallow waterflow and gas hydrates, and the improved...
