... Abstract In current research authors look for and analyze an alternative to traditional production logging tools (PLT) and high-technological multisensor tools in horizontal wells. Trancient temperature profiles measurements using fiberoptic distributed stationary sensors (DST) are chosen...

... sensors for the optimal control of the oxygen injection in real-time. The framework was examined on a synthetic reservoir model with various producers and injectors. Each producer and injector contain various wireless high temperature sensors that are connected to each other. The framework then utilizes...

... ABSTRACT In this paper, we present a field test of temperature sensors, based on arrays of Fiber Bragg Gratings (FBG), on a co-generation steam turbine operating at the GE Oil&Gas Nuovo Pignone facility in Florence. This unit has been upgraded with new components and high efficiency stages...

... the most suitable tools and equipment that are available in the industry and most useful to this project at very shallow depths and in real-time monitoring. It was decided that the minor temperature variation against the contributing zone could be captured real-time by DTS (Distributed Temperature Sensors...

... with a defined well structure. Pressure, temperature and flow rate in the well system are calculated in the motherbore (main hole) and in the laterals. Then we use the inverse model to interpret the flow rate profiles from the temperature and pressure data measured by the downhole sensors. A gradient-based...

... equipments, it is very challenging to obtain specific injection rate for each perforated zone. Temperature variations in the well bore, outside the casing, are available using new technology such as distributed temperature sensor (DTS) fiber optic cables. The main objective of this study is to relate...

... instances, an alternative is required. This paper presents a new procedure based on multirate testing in combination with distributed temperature sensors (DTS), an electric submersible pump (ESP) fitted with a gauge in the commingled fluid stream, and conventional surface testing. The additional test rates...

.... Distributed Temperature Sensors (DTS) Physics The distributed temperature from the top of the well to the ultimate depth of the line is measured by sending 10 nanosecond bursts of laser light down the optical fiber within the slick-line cable. Light is scattered as the pulse travels through the fiber...

... ABSTRACT Brillouin-scattering-based fiber optic distributed strain and temperature sensors (DSTS) has been applied to measure the longitudinal and hoop strain in an internally pressurized 1.8 m long end-capped steel pipe with wall thinning defects. The preembedded defects, which constitute 50...

... technologies like wireline production logging commercially inefficient. Accordingly, BP has chosen to use a mixture of permanently installed distributed temperature sensor (DTS) monitoring supported by some PLT monitoring in preference to PLT monitoring alone. The reasons are detailed below: The platform...

... using a highly sensitive receiver. This procedure can pinpoint the location of blockages and other problems more quickly and inexpensively than traditional methods, which typically rely on the intrusive placement of temperature sensors. This procedure has been tested in a number of mature oil fields...

... Abstract We present an interpretation methodology for analysis of temperature profiles obtained in horizontal injectors with fiber optic distributed temperature sensors. We consider injection as a non-isothermal process, due to the contrast in the temperature of injected fluid and reservoir...

The precision-stabilized lengths are disposed at intervals along each fiber, with most of the rest being in the insulated container. The test rig is contained in an environmentally conditioned room: the insulated container internal temperature...
