Abstract: There is provided a method and an apparatus analysing the condition of a liquid conduit system. Data is received from at least one sensor indicative of pressure within the system and then processed to generate an inflexion coded data subset for each sensor. The inflexion coded data is then cycle counted across at least one time period to generate a second data subset for each time period comprising a count of pressure cycles, the amplitude of these pressure cycles and an average pressure. A cumulative pressure-induced stress can then be calculated for each of the at least one time periods using the second data subset.

Abstract: A method of evaluating processing imprint on seismic signals includes receiving a first and a second seismic dataset of a reservoir. A first and a second synthetic dataset are generated, where the second synthetic dataset is generated by multiplying at least a portion of data in the first synthetic dataset by a scaling factor. A first and a second combined dataset are generated by adding the respective seismic dataset and the respective synthetic dataset. A first and a second processed dataset are generated by applying a seismic processing step on the first and the second combined dataset, respectively. A difference factor between the first and the second processed dataset is calculated. Based on the difference factor and the scaling factor, it is determined whether the seismic processing step is able to preserve signal amplitude changes between the first and the second seismic dataset.

A power supply device generates a prediction value of an error signal from first and second error signals, and controls an output voltage so that the prediction value lies between first and second threshold values.

The second error signal is obtained by converting an error voltage based on the difference between the output voltage and the reference voltage at a second timing.

Abstract: The present disclosure relates to Target-Enclosing Extended Image deconvolution. In a first aspect, the present disclosure provides methods to construct, from surface seismic reflection data, extended image gathers, i.e. time- and space-varying fields corresponding to virtual sources and receivers inside a subsurface volume, to retrieve both local reflection and local transmission responses corresponding to two datums at depth: an original observation datum and a second datum completely enclosing a chosen target subsurface volume away from the original observation datum (e.g., enclosing a target reservoir at depth). The methods of the present disclosure retrieve responses that are devoid of interference due to structures that may exist both above and below the target volume, i.e., the retrieved responses correspond only to the properties of the medium within or inside of the target volume.

When a determination is made that the design is not satisfactory, the filter design is modified and the process is repeated. When a determination is made that the design is satisfactory, a filter design description is output.

Abstract: Subsurface exploration using In-Situ tests such as SPT, CPT, CPTu, DMT, and PMT predicts inaccurately engineering properties of soils and intermediate geomaterials and thereby predicts incorrect load-settlement relationship of piles; variations or errors in engineering properties predicted by one empirical correlation to another correlation could be up to 50% or greater. For soft to very soft soils, engineering properties cannot be predicted as the SPT only provides information such as WOR and WOH. To overcome this problem, the invention of the application consists of performing subsurface exploration using load tests on short model piles with or without instrumentation at various depths of a soil deposit for determining accurately the above-mentioned properties. For very soft soils, a hung balance is used to hang drill rods and short model pile from a drill rig boom or from a platform with soil anchors to prevent its overturning, and then perform the load test.
