Abstract High-grade permafrost hydrate concentrations in shallow geological traps constitute primary hydrate natural gas exploration objectives. The hydrate in these deposits can be compared with authigenic mineral deposits because the concentrated gas was largely already in the geological traps before ...
Abstract Permafrost presents one of the key challenges to development of oil and gas reserves in both onshore and near-shore Arctic fields. The settlement due to permafrost thawing has been observed for warm foundations and pipelines. Such settlement is considered a severe threat to the integrity of ...
Abstract Every human activity in the offshore Arctic, or anywhere offshore for that matter, emits some level of sound into the marine environment. Depending on intensity, and to some extent frequency, underwater sound can be a nuisance or even physically harmful to marine life. The indigenous people ...
Abstract The scale of loss resulting from the Gulf oil spill and the formidable costs of liabilities has stimulated demands for rethinking our values and how they are integrated in key decision making. Recent experience in oil spill risk assessments will be presented to highlight the criticality of ...
Abstract Industry has experienced a significant increasing on the number of floating systems in the recent years. Current order book and potential projects under study indicate also that this number might increase even more significantly along the next 10 years. At some point in their lives, these facilities ...
Abstract Shipwrecks with wooden hulls are underrepresented in the archaeological record from shallow federal waters of the central and western Gulf of Mexico (defined as less than 600 feet deep), yet they tend to be older and arguably more abundant than shipwrecks with metal hulls. This paper quantifies ...
Abstract Deepwater project portfolios are complex and high risk with a lot of uncertainty. They present unique challenges and require capital intensity to initiate projects. Most authors argue that specific factors relevant for successful competitive performance vary from business to business and industry ...
Abstract Current technology offers the operators of well-intervention equipment little opportunity to receive accurate and real-time visual feedback from the borehole when the fluid contents are opaque. As a result, the majority of operations are performed 'blind' leading to extensive use of time and ...
Abstract The world wide market for LNG continues to grow rapidly. Traditionally, base load LNG plants have provided the majority of this LNG supply. As the industry has grown, base load plants have grown increasing larger and more difficult to site. Additionally, the number of fields with sufficient ...
Abstract It is generally understood that hydrocarbon exploration in the circumpolar Arctic will increase in the coming years to meet growing global energy demands. Concurrent with consumer demand is an equally important obligation to demonstrate adequate environmental understanding and risk-based operations planning ...
Abstract Disposal of produced fluids, during different well activities, has been one of the main challenges for field operators due to environmental and economical concerns. The limitations on the discharge of oily wastes in addition to other regional regulations have resulted in several efforts to ...
Abstract PTTEP Siam Limited (PTTEPS), a subsidiary of PTT Exploration and Production Public Company Limited (PTTEP), has pioneered a Clean Development Mechanism (CDM) project that takes aim at recovering and then using associated gas from the oil wells of Thailand's Sao Thian-A field. Situated ...
Abstract Effective removal of drilling-mud filter cake during well completion is essential to reduce the formation damage caused by drilling activities in many production and injection wells. This task is very difficult to achieve, especially in horizontal/multilateral wells. Harsh chemical treatments ...
Abstract Shell aspires to maximize unattended operations for all upstream E&P "green?? and "brown?? field assets using the appropriate level of automation. The benefits associated with down manned operations include the following: • Reducing staff exposure to travel hazards e.g., driving, sailing ...
Abstract This paper investigates an idea for chemical imbibition using surfactant formulations to stimulate oil recovery from oil shale. One goal of this research is to identify a formulation that promotes imbibition while minimizing clay swelling and formation damage. Experiments directed toward this ...
Abstract From 1998 to 2010, after years of decline, Russia's oil production increased by 66% from 6.2 million bbl/day to a post-Soviet record of 10.3 million bbl/day1. Significantly, this period also witnessed the creation of an independent oilfield services (OFS) sector as Russian operators adopted ...
Abstract There is a general uncertainty regarding the issues affecting shale stability in gas shale reservoirs. True swellable smectite is not present in most of the reservoirs currently being exploited. Illite and illite/smectite are the principal clay components, and they do have a distinct fixed ...
Abstract The goal of this work is to change the wettability of a carbonate rock from mixed-wet towards water-wet at high temperature and high salinity. Three types of surfactants in dilute concentrations (<0.2 wt%) were used. Initial surfactant screening was done on the basis of aqueous stability ...
Abstract The Intermountain West Oil and Gas BMP Project (BMP Project) is a collaborative effort of the Natural Resources Law Center and its partners, including the Environmentally Friendly Drilling Program. The BMP Project has developed a comprehensive, free-access, searchable, web-based database of ...
Abstract This paper discusses the prejob research and eventual use of a hydraulic workover (HWO)/snubbing unit for a subsea flowline intervention at the Nansen Spar in the Gulf of Mexico (GOM). Located in a water depth of 3,670 ft (1119 m), the Nansen Spar has been in production since 2002 (Fig. 1). ...
