The increasing oil demand around the world along with the depletion of onshore and shallow water oil reserves have forced the oil companies moving into the development of deepwater subsea hydrocarbon reservoirs. Drilling fluids play a key role in all drilling operations, but they get a greater relevance in deepwater environments where the technological challenges of drilling at these extreme conditions generate significant operational risks as well as very high costs during the development of this kind of fields. The operational issues and concerns related to the drilling fluid design and application for deepwater fields are generally well known: narrow pore/fracture pressure gradient margins, wellbore stability, clay swelling, gas hydrates formation, formation damage, salt formations, lost circulation, stuck pipe, cuttings transport and environmental and safety aspects. Therefore, the present chapter aims to give an overview on the main challenges and research related to drilling fluid design and application for deepwater fields through the revision of the state of the art of the current and innovative technological solutions reported in literature.

“…distance between the drill collar and the wellbore wall was assumedz. With the acceleration of 80 g, the time for the string to cover this 2 in.-distance is given by: d= 0.5 atz (7) where d is the distance and t the time. Solving the atxwe equation for time yields: t2 = 2 X 0.05 rn/ 784 IU/S2 = 12.94 x lo"f S2 t= 1.13 x 10"2seconds…”

A conceptual model and simple method to quantifj the energy associated with the main events during drilling are proposed here. However, evaluation of the consequences in terms of damage to the reek requires qxeially designed tests to determine the response of the reek in terms of energy. This approach can explain the failure mechanisms usually observed in laboratory tests and most of the problems faced in the field. In view of this new approach, adequate solutions to effectively alleviate current instability problems are discussed, Successful field cases are described demonstrating the validity of the suggested failure mechanisms.

“…These tests give completely different results that are often far from reality. Immersion tests give a visual confirmation of the effect of different types of fluid on rock structure (Rabe et al 2002;Santos et al 1997). Immersion tests are used to evaluate the suitability of different drilling fluids for a particular shale formation.…”

“…Immersion tests are used to evaluate the suitability of different drilling fluids for a particular shale formation. However, the absence of the confining pressure is a major limitation to the method (Santos et al 1997). In this study, the interaction of wellbore fluids with shale was studied as a function of polymer concentration and salt type and concentration.…”

This paper presents qualitative techniques for evaluating shale-fluid interaction. Undesirable shale-fluid interactions lead to wellbore instability, formation damage and other problems that cost the petroleum industry millions of dollars annually. A simple desktop test method, such as immersion testing, can help production engineers choose the appropriate shale inhibitors such as salt, tetramethylammonium chloride (TMAC) and polymers that can effectively reduce the impact of oilfield fluids invading shale and causing it to swell or disperse. The swelling tendency of shale is highly dependent on clay mineralogy and other properties, such as porosity and permeability. A series of immersions tests was performed to study the combined and isolated effects of salt, TMAC, and polyacrylamide on preventing shale from becoming unstable. The merit of each fluid system in shale inhibition is probed for Woodford, Chattanooga and Pride Mountain shale. Rheology of bentonite slurries is studied with different salts and TMAC to probe their efficiency in preventing the swelling of bentonite clay. Additionally, rheology of bentonite with anionic and cationic polyacrylamide and salt is investigated.
