Well placement optimization for offshore oilfield based on Theil index and differential evolution algorithm

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
Proper well placement should match the heterogeneity of reservoir and development schedule, in which case the displacement is balanced. A balanced displacement process can achieve a good development performance of reservoir.

Correcting Breaks in Temperature and Humidity Observations: Implications for Climate Variability Analysis in Austria

open access: yesInternational Journal of Climatology, EarlyView.
A 2‐h shift in the timing of evening observations in 1971 resulted in a discontinuity in the estimation of daily means of air temperature and humidity across all climate stations in Austria. This study employs hourly observations to, for the first time, comprehensively quantify and correct this break.

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...
