title: Metagenomic sequencing library of Shengli oilfield sample
design: The oil-sand sample was collected from Shengli oilfield (Shandong) on 18 October 2018 into bottles, which were transported to the laboratory where they were stored at 4 C. The sample was used as inoculum to perform enrichment with anaerobic medium in vials. After 253 days of enrichment, the genomic DNA was extracted.
