A "burden of proof" is a party's duty to prove a disputed assertion or charge, and includes the burden of production (providing enough evidence on an issue so that the trier-of-fact decides it rather than in a peremptory ruling like a directed verdict) and the burden of persuasion (standard of proof such as preponderance of the evidence). [2 ...
The satisfaction of the evidential burden has sometimes been described as "shifting the burden of proof", a label which has been criticized because the burden placed on a defendant is not the legal burden of proof resting on the prosecution. [6] To satisfy the burden, there must be evidence which both supported the issue and which is ...
For many years, the world's longest borehole was the Kola Superdeep Borehole in Russia. From 2011 until August 2012 the record was held by the 12,345-metre (40,502 ft) long Sakhalin-I Odoptu OP-11 Well, offshore the Russian island Sakhalin. [11] The Chayvo Z-44 extended-reach well took the title of the world's longest borehole on 27 August 2012 ...
A caliper log is a well logging tool that provides a continuous measurement of the size and shape of a borehole along its depth [1] and is commonly used in hydrocarbon exploration. The measurements that are recorded can be an important indicator of wash-outs, cave ins or shale swelling in the borehole, which can affect the results of other well ...
There are various standards of evidence, standards showing how strong the evidence must be to meet the legal burden of proof in a given situation, ranging from reasonable suspicion to preponderance of the evidence, clear and convincing evidence, or beyond a reasonable doubt. There are several types of evidence, depending on the form or source.
In the oil industry, a deviation survey, [1] or simply a survey, is the measurement of a borehole's departure from the vertical, expressed in degrees (°).. When a well plan dictates the drilling of a straight borehole, surveys are periodically taken to ensure that it will hit its target and also to ensure that it does not trespass underneath different property lines.
The burden of production is a minimal burden to produce at least enough evidence for the trier of fact to consider a disputed claim. [ 27 ] : 16–17 After litigants have met the burden of production and their claim is being considered by a trier of fact, they have the burden of persuasion, that enough evidence has been presented to persuade ...
It is the borehole core recovery percentage incorporating only pieces of solid core that are longer than 100 mm in length measured along the centerline of the core. In this respect pieces of core that are not hard and sound should not be counted though they are 100 mm in length.
