An integrated laboratory experiment of realistic diagenesis,perforation and sand production using a large artificial sandstone specimen

引用

Journal of Rock Mechanics and Geotechnical Engineering 2021年第1期13卷 154-166页

作者： Ashirgul Kozhagulova Ainash Shabdirova Nguyen Hop Minh Yong Zhao School of Engineering and Digital Sciences Nazarbayev University53 Kabanbay Batyr AvenueNur-SultanKazakhstan Fulbright University Vietnam 105 Ton Dat TienHo Chi Minh CityViet Nam

Sand production is,a challenging issue in petroleum industry,mainly associated with weak unconsolidated formations.A novel testing procedure and a new apparatus were developed to conduct an integrated experiment of diagenesis,perforation and sand production on a single large cylindrical artificial sandstone specimen,where solid and fluid pressures can be independently controlled such that realistic reservoir historical conditions can be well simulated in the *** injection can be performed in both radial and vertical directions,where both single-and two-phase flows can be implemented for study of sand production behaviors at different reservoir’s maturity *** equipment consists of an intensive instrumentation system to monitor pressures,displacements and material states *** produced sand particles were filtered and monitored in real-time for the study of time-dependent *** experimental results showed similar patterns to that observed in the field and provided valuable insight for the development of prediction methods for sand production of similar materials.

Accidents during Tanker Accident in Confined Spaces

引用

Journal of Shipping and Ocean Engineering 2017年第5期7卷 203-209页

作者： Omar Mohamed Fouad Farid Maritime Safety Institute AAST & MT Alexandria 1029 Egypt

One of the major hazards when working onboard Tankers is working in confined spaces, improving the procedures in working in such spaces is obvious, but developing the equipments used in rescue operation is rare to happen, that＇s why this paper is focusing on differentiating between the manual ＆ more developed equipments used specially in rescuing the crew in such an adequate time, to save the workers＇ life. The manual way is called ＂MUCKY CRANE＂ which is used for rescue purposes onboard tankers, in any of the confined spaces, should be replaced by excel crane which is air or hydraulic driven machine, to achieve better results. As safety precautions measures taken in such tasks are not enough for the required objective achievement. Such safety procedures have been discussed and critical situations have been pointed out.
