Preface

This proceeding includes original and peer-reviewed research papers from 2019 International Conference on Oil & Gas Engineering and Geological Sciences (OGEGS 2019). OGEGS 2019 was held in Dalian, China on September 28-29, 2019. OGEGS aims to bring together leading academic scientists, researchers and research scholars to exchange and share their experiences and research results on all aspects of Oil & Gas Engineering and Geological Sciences. It also provides a platform for academic scientists, researchers and research scholars, doctors, doctoral students and related professionals to present and discuss the most recent innovations, trends, and concerns as well as practical challenges encountered and solutions adopted in the fields of Oil & Gas Engineering and Geological Sciences. All authors and participants are kindly encouraged to contribute to and help shape the conference through submissions of their research abstracts, papers and posters. OGEGS 2018 received 785 manuscripts, and 234 submissions had been accepted by our reviewers. By submitting a paper to OGEGS 2019, the authors agreed to the review process and understood that papers undergo a peer-review process. Manuscripts were reviewed by appropriately qualified experts in the field selected by the conference committees, who gave detailed comments and-if the submission was accepted the authors would submit a revised version that took into account this feedback. All papers were reviewed using a double-blind review process: authors declared their names and affiliations in the manuscript for the reviewers to see, but reviewers did not know each other’s identities, nor did the authors receive information about who had reviewed their manuscript. The Committees of OGEGS 2019 invested great efforts in reviewing the papers submitted to the conference and organizing the sessions to enable the participants to gain maximum benefit. Hopefully, all participants and other interested readers will benefit scientifically from the proceedings and also find it stimulating in the process. With our warmest regards, Zhibin You Conference Organizing Chair Wuhan, China
