Crustáceos decápodos da costa do Maranhão, Brasil

This paper presents a list of crustacean decapods occuring in the State of Maranhão coast, Brazil, based on the study of collections of the Departamento de Oceanografia (Universidade Federal de Pernambuco) and Laboratório de Hidrobiologia (Fundação Universidade do Maranhão) and on litterature records. There are recorded 149 species (37 species of Natantia and 112 species of Reptantia)

Results of July 15, 2010 IADC Stick-Slip Mitigation Workshop

Abstract: This paper presents the results from a workshop on stick-slip mitigation held in Houston on July 15, 2010. This workshop, sponsored by the IADC ART Future Technology Subcommittee, brought technology leaders and engineers together to discuss issues related to Stick-Slip mitigation. Led by specialists with operating and technology companies, its goal was to educate the industry regarding existing technologies available to address this issue as well as identify the need for possible future technologies. In addition to presenting technical results, the paper describes the unique structure of the workshop: (1) opening, non-commercial presentations wherein the science of stick slip and the business case for its mitigation were reviewed; (2) a series of short presentations by various providers with technologies to identify or mitigate stick-slip; (3) a round table discussion, involving both the presenters and the audience, to assess the effectiveness of these technologies and assess areas where further technology, education, or process improvement is needed. This was all condensed into an afternoon so as to accommodate the demanding schedules of the participants and audience. This workshop is the first of a series of planned workshops to address technology needs which were identified in an industry survey conducted by the IADC Advanced Rig Technology committee last year and reported in SPE 128953.</jats:p
