Inventor: AUZERAIS FRANCOIS M
IPC: E21B21/06
Filed: 2012-12-13
Abstract: Compositions of lost circulation materials are provided that are useful for identifying the location of fluid loss in a wellbore. The compositions include additives which enhance a property of the composition such that they can be detected by an LWD  or MWD  tool capable of measuring the property when the composition is deployed in a region of loss, and can be distinguished by the LWD or MWD tool from the formation and mud fluid.  Methods are also provided for using the composition to detect the location of fluid loss and for controlling the loss of fluid from the wellbore. The methods involve deploying the compositions in loss regions by adding the compositions to drilling mud, and measuring a property of the compositions using an LWD or MWD tool.

Abstract: The present technology relates to an encoding device and a encoding method as well as a decoding device and a decoding method which are capable of suppressing the amount of information without degrading the image quality of an image of a view used when securing compatibility in a case when performing encoding for a multi-view image. A compatibility-use encoder encodes an image A1 which is a compatible image to generate a compatible stream. An image conversion unit decimates an image B1 and an image C1 which are auxiliary images. An auxiliary encoder encodes the decimated auxiliary images to generate an encoded stream of the auxiliary images. A frame packing unit transmits the compatible stream and the encoded stream of the auxiliary images. The present technology can be applied, for example, to an encoding device for encoding a 3D image in a multi-view method.
