Abstract An Automatic Well Planner (AWP) is used to efficiently adjust pre-determined well paths honor near-well properties and increase overall production. AWP replicates modern geosteering decision-making where adjustments pre-programmed are driven by continuous integration of data obtained from logging-while-drilling look-ahead technology. In this work, combined into a robust optimization sc...

The main oil layer of Grape Flower in X Oilfield has entered the late stage high-extra-high water cut, and remaining distribution is uneven, so as to ensure development effect purpose block. Based on theory fine sedimentology, sedimentation characteristics PІ1 1 PІ2 2 deposition time units were studied. Combined with sedimentary logging data meandering river delta, facies model was classified d...

Although the multiplication of bacteriophages (phages) has a substantial impact on the biosphere, comparatively little is known about how the external environment affects phage production. Here we report that sub-lethal concentrations of certain antibiotics can substantially stimulate the host bacterial cell’s production of some virulent phage. For example, a low dosage of cefotaxime, a cephalo...
