According to Plews and Zhao, task-based language learning can suffer in practice from poorly informed implementation and adaptations that alter its fundamental nature. They say that lessons are frequently changed to be more like traditional teacher-led presentation-practice-production lessons than task-based lessons. [16]
The oil and gas industry spends only 0.4% of its net sales on research & development (R&D) which is in comparison with a range of other industries the lowest share. [36] Governments such as the United States government provide a heavy public subsidy to petroleum companies , with major tax breaks at various stages of oil exploration and ...
Free point: The highest point at which the drill pipe is "free" or not stuck. Free-point tools are designed to measure torque and stretch in tubing, casings, and drill pipes and to provide accurate free pipe indication. A common method which involves deploying a wireline device to estimate the depth at which the pipe string is stuck.

In the petrochemical industry pressure is controlled by maintaining a constant pressure in the upper gas space of a vessel. [1] [9] [4] A pressure controller (PIC) adjusts the setting on a pressure control valve (PCV) that feeds gas forward to the next stage of the process. A rising pressure in the vessel results in the PCV opening to feed more ...
Oil field in California, 1938. The modern history of petroleum began in the nineteenth century with the refining of paraffin from crude oil. The Scottish chemist James Young in 1847 noticed a natural petroleum seepage in the Riddings colliery at Alfreton, Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a thicker oil suitable for ...
Scale is a common term in the oil industry used to describe solid deposits that grow over time, blocking and hindering fluid flow through pipelines, valves, pumps etc. with significant reduction in production rates and equipment damages. [2] [3] Scaling represents a major challenge for flow assurance in the oil and gas
