A method of cross-tool optical fluid model validation includes selecting verified field data measured with a first sensor of an existing tool as validation fluids and selecting a second sensor for a new tool or on a different existing tool. The method may also include applying cross-tool optical data transformation to the validation fluids in a tool parameter space from the first sensor to the second sensor, and calculating the synthetic optical responses of the second sensor on the validation fluids through cross-space data transformation. The method may further include determining a new or adjusting an existing operational fluid model of the second sensor in a synthetic parameter space according to the candidate model performance evaluated on the validation fluids, and optimizing well testing and sampling operation based on real-time estimated formation fluid characteristics using the validated fluid models of the second sensor in an operating tool.

One aspect provides a method, including: obtaining sensor data from a ground penetrating radar (GPR) unit; analyzing, using a processor, the sensor data to detect a first object and a second object, the second object being associated with the first object based on location; identifying, with the processor, an underground pipe feature based on the analyzing; associating a position of the underground pipe feature with a location in a pipe network; selecting a subset of the pipe network including a pipe segment associated with the position of the underground pipe feature; and providing the subset of the pipe network as displayable data to a display device.

The servo loading control system includes a servo motor, a planetary roller screw electric cylinder and a loading rod. The data acquisition system includes a displacement transducer, an axial force meter, a pore pressure transducer, an earth pressure transducer and an industrial camera. The servo loading control system is connected to an excavation plate through the loading rod to control the excavation plate to move back and forth along an axial direction of the shield tunnel model at a set speed to simulate failure of the shield tunnel face. A method for simulating a progressive failure of a shield tunnel face is also provided.

A graphical representation of an image of a subterranean formation along with log properties of the formation provided in a single graphical representation. Logged formation property values are coded into graphic representations of images of the formation in order to provide a graphical representation which allows the user to visually perceive the formation images and the logged formation properties simultaneously. A method may include receiving an image of a formation, the image including image values based on the formation, and also receiving a log property of the formation, the log property including log property values based on the formation. The log property values of the formation are correlated to corresponding locations in the image. A transfer function with the image values and the correlated log property values as inputs is determined. Based on the transfer function, a joint graphical representation of the image and the log property is rendered.

The present invention relates to the technical field of long-term in-situ monitoring of sediment disturbance in deep-sea surface mineral mining, and more particularly to a device for monitoring deep-sea sediment environment in mining polymetallic nodules. The monitoring system comprises: acoustic Doppler flow profilers, a spontaneous potential probe, a turbidity meter and an underwater camera. The invention can realize long-term in-situ observation of sediment disturbance, and can realize the mechanical recovery of probe rod-type equipment without large-scale mechanical devices, thereby reducing the overall weight of the recovery equipment and increasing the probability of successful equipment recovery. Compared with the existing long-term in-situ observation equipment on the seabed, it is more environmentally friendly, efficient, energy-saving and reliable.
