Abstract: Oilfield and wellbore data may include geophone data (seismic) and airborne surveys such as microseep data, as well as fiber optic measurements collected utilizing a distributed sensing system. Continuous monitoring of various oilfield and wellbore properties, such as temperature, pressure, Bragg gradient, acoustic, and strain, and the like, may generate a large volume of data, possibly spanning into several terabytes. Embodiments of the present invention provide techniques for visualizing a large volume of such measurements taken in an oilfield or wellbore without down-sampling measurement data.

Abstract: The invention discloses an omnidirectional vector geophone, comprising: eight wave detectors and support structures thereof, the support structures are used for supporting the eight wave detectors such that bottom surfaces of each two wave detectors are on one of regular triangle surfaces of a regular tetrahedron, crossing points of working shafts of the two wave detectors that are on the same regular triangle surface that cross with the regular triangle surface are both on an angular bisector of an angle of the regular triangle surface and are symmetric with respect to the center of the regular triangle surface. In the invention, based on divergence and curl equations of field theory, a particular spatial motion full-vector detection structure is designed to realize detection of full information including frequency, amplitude, phase, vibration direction of the seismic wave field, especially divergence and curl of a wave force field, to form a completely new omnidirectional vector geophone structure.

Abstract: The present invention relates to a system for marine seismic refraction survey using a remotely piloted air/water drone and a method thereof for acquiring refracted wave by providing a receiver on the air/water drone among marine seismic methods, being configured to include: a surveyvessel provided with a seismicsource generating a sound; and the air/water drone moving tethered to the surveyvessel while floating on the sea or operating under water and being capable of moving to a desired location by generating a lift force and a turning force through remote control. In addition, the system is to be used for marine seismic refraction survey by providing a hydrophone and streamer and a recording system which may record the seismic wave on an air/water drone, a remotely piloted marine observation system, whereby an effect is given to be able to acquire data of seismic refraction.

Abstract: A seismic sensor that suppresses power consumption operates in a power-saving mode and a measurement mode in which the power consumption is larger than that in the power-saving mode. The seismic sensor includes a measurement unit that measures an acceleration, a filtering unit that, if the acceleration measured by the measurement unit exceeds a predetermined threshold, causes a shift from the power-saving mode to the measurement mode to be performed, and performs filtering on the measured acceleration, an earthquake determination unit that determines whether or not an earthquake has occurred based on the filtered acceleration, and an index calculation unit that, if where the earthquake determination unit determined that an earthquake has occurred, calculates an index value indicating the scale of the earthquake. A shift from the measurement mode to the power-saving mode is performed if the earthquake determination unit determined that no earthquake has occurred.

Abstract: Techniques are disclosed relating to configuring a marine seismic survey. In some embodiments, a vessel may be coupled to one or more seismic sources and one or more seismic streamers, and a second vessel may be coupled to one or more far offset seismic sources. The near offset sources may be configured to actuate according to a shot point interval; the far offset sources may be configured to actuate according to a longer shot point interval. In some embodiments, the longer shot point interval may be a multiple of the near offset source shot point interval. Determining the first and second shot point intervals may be based in part on, for example, the wave frequencies of the far offset sources, the requirements of a full wave inversion process, or various configurational parameters of seismic surveys.

Abstract: A vibration-analysis system has one or more server computers, one or more client-computing devices, and one or more vibration-detection units functionally connected via a network. The one or more vibration-detection units may be deployed in a site for vibration detection. The detected vibration data is sent to the one or more server computers for vibration/seismic analysis. The system disclosed herein may be used for vibration/seismic survey, vibration monitoring, and the like. Each vibration-detection unit may have a vibration-detection sensor and a positioning module for automatically determining the position thereof. The vibration-detection units may be geophones and the system may have a signal process module for compensating for the distortion introduced by the geophones.

Abstract: A method and apparatus for handling of sensor capsules and their inner components during deployment and retrieval of a seismic cable into the sea by a vessel where the seismic cable includes seismic node casings to contain the sensor capsules when the seismic cable is in the sea. The method includes the following steps: withdrawing a sensor capsule from a sensor capsule storage; withdrawing a battery unit from a battery unit storage; withdrawing a control unit from a docking station; combining the control unit and battery unit into a control/battery unit; inserting the control/battery unit into the sensor capsule and closing the sensor capsule; and loading the sensor capsule into a seismic node casing.

Abstract: A method for manufacturing an optical-fibre sensor device is provided, including an enclosure defining a recess and an optical-fibre sensor including an optical-fibre and a device for holding the sensor that is rigidly connected to the optical fibre, the optical fibre passing through the holding device between two attachment points provided on the holding device. The method comprises the steps of: positioning the optical-fibre sensor in the enclosure to pass the fibre through two passage openings provided on the enclosure, the optical fibre generally extending along a longitudinal axis in the recess, which defines two optical-fibre portions in the enclosure, on either side of the holding device, each fibre portion extending between one of the points for attachment of the holding device and one of the passage openings in the enclosure, substantially in a straight line; holding the optical-fibre sensor in position; performing a differential elongation of the enclosure relative to the optical-fibre sensor in the longitudinal direction, and towards the outside of the enclosure, while the optical-fibre sensor remains held in position; attaching the optical fibre to the enclosure at the passage openings.
