Light hydrocarbons accumulated in subsurface soil by long-term microseepage could favor the anomalous growth of indigenous hydrocarbon-oxidizing microorganisms, which could be crucial indicators of underlying petroleum reservoirs. Here, Illumina MiSeq sequencing of the 16S rRNA gene was conducted to determine the bacterial community structures in soil samples collected from three typical oil an...

The β-proteobacterium Aromatoleum aromaticum degrades the aromatic ketone acetophenone, a key intermediate of anaerobic ethylbenzene metabolism, either aerobically or anaerobically via a complex ATP-dependent acetophenone carboxylase and a benzoylacetate-CoA ligase. The genes coding for these enzymes (apcABCDE and bal) are organized in an apparent operon and are expressed in the presence of the...

We study a controlled corporate experiment in which loan officers were compensated to engage in loan prospecting in addition to the traditional loan screening. Loan prospecting led to larger loan sizes (+15%) and higher origination rates (+31%) while keeping the traditional credit quality threshold and interest rate intact. Loan officers attempt to influence the decision making process: loan of...

Reliable geothermal data are required for basin and petroleum system modeling. The essential shortcomings of the methods results previous investigations lead to a necessity reappraise on thermal properties heat flow. A new, advanced experimental basis was used provide reliable vertical variations in formation flow area surrounding prospecting borehole drilled through an unconventional hydrocarb...
