Abstract:
In some implementations, optical analysis systems use an integrated computational element (ICE) that includes a planar waveguide configured as an ICE core. In other implementations, the ICE used by the disclosed optical analysis systems includes a planar waveguide configured as a spectrograph, the spectrograph to be integrated with a conventional ICE.

APPARATUS, SYSTEMS, AND METHODS MAY OPERATE TO TRANSMIT ENERGY TO A NANOFIBER SAMPLING COIL AND/OR A NANOFIBER REFERENCE COIL. FURTHER ACTIVITY MAY INCLUDE RECEIVING THE ENERGY AS MODIFIED BY EVANESCENT INTERACTION WITH A SAMPLED MATERIAL LOCATED PROXIMATE TO THE SAMPLING COIL AND/OR AS MODIFIED BY PROPAGATION THROUGH THE REFERENCE COIL, AND COMPARING THE ENERGY MODIFIED BY EVANESCENT INTERACTION WITH THE ENERGY MODIFIED BY PROPAGATION THROUGH THE REFERENCE COIL TO DETERMINE A SPECTROSCOPIC PROPERTY OF THE SAMPLED MATERIAL. ADDITIONAL APPARATUS, SYSTEMS, AND METHODS, INCLUDING THE USE OF NANOFIBERS AND FLUORESCENCE INDUCED BY EVANESCENT RADIATION TO CONDUCT SPECTROSCOPIC ANALYSIS, ARE DISCLOSED.
Abstract:
Abstract A computer accepts dead-oil properties of a reservoir fluid sampled from a well. The dead-oil properties are the measured composition of the reservoir fluid after volatile components of the reservoir have substantially vaporized. The computer analyzes the dead-oil properties and a constraint 5 to produce estimated live-oil properties of the reservoir fluid. The live-oil properties are the composition of the reservoir before the volatile components have substantially vaporized. The computer uses the estimated live-oil properties to make a decision regarding the well.
Abstract:
In or near real-time monitoring of fluids can take place using an opticoanalyiical device that is configured for monitoring the fluid. Fluids can be monitored prior to or during their introduction into a subterranean formation using the opticoanalyiical devices. Produced fluids from a subterranean formation can be monitored in a like manner. The methods can comprise providing an acidizing fluid comprising a base fluid and at least one acid; introducing the acidizing fluid into a subterranean formation; allowing the acidizing fluid to perform an acidizing operation in the subterranean formation; and monitoring a characteristic of the acidizing fluid or a formation fluid using at least a first opticoanalyiical device within the subterranean formation, during a flow back of the acidizing fluid produced from the subterranean formation, or both.
Abstract:
fonte de luz. fontes de luz são fornecidas com emissão melhorada de baixa frequência (por exemplo, próxima do infravermelho). algumas modalidades reveladas incluem um filamento e pelo menos um elemento rerradiador. o filamento aquece o elemento rerradiador até uma a temperatura estável que é pelo menos um quarto da temperatura absoluta do filamento. como aqui revelado, uma área de superfície aumentada é fornecida pelo elemento rerradiador que fornece uma irradiação melhorada de infravermelho a partir da fonte de luz. padrões ou texturas da superfície podem ainda aumentar a área da superfície do elemento rerradiador. várias formas tais como discos, colares, tubos são ilustradas e podem ser combinadas para peculiarizar o perfil do espectro de emissão da fonte de luz. algumas modaliddes específicas empregam um revestimento sobre o bulbo como elemento rerradiador. o revestimento pode ser posicionado para ocluir a luz do filamento ou para aumentar a luz do filamento, dependendo da particular aplciação. os vários elementos rerradiadores podem ser posicionados por dentro ou por fora do bulbo.
Abstract:
Various embodiments include apparatus and methods to operate a tool downhole in a well, where the tool has an optical computation element to determine different properties of downhole structures. Such an optical computation element can be structured to provide optical analysis of fluid and material composition of the downhole environment associated with a drilling operation. The data measurements from the optical computation element can be used in a geosteering operation. Additional apparatus, systems, and methods are disclosed.
