Abstract: A method for evaluating and optimizing scale management at a subsurface for improved well performance may include performing multiple first tests, where each first test combines a first fluid with a second fluid, wherein the first fluid comprises a concentration of a scale inhibitor and a chemistry of additional fluid components. The method may also include identifying an optimal mixture of the first fluid among the first tests, where the optimal mixture comprises a minimum concentration of the scale inhibitor that reduces scale deposition. The method may further include performing a second test that combines the first fluid with the scale inhibitor, the second fluid, and rock. The method may also include evaluating a concentration of the scale inhibitor in aqueous phase after a period of time after initiating the second test. The method may further include identifying a target fluid for use in a field operation at the subsurface.

Abstract: Disclosed is a computer-implemented method of determining a control parameter for controlling a medical imaging device. The disclosed method encompasses acquiring an operating parameter such as an imaging depth of an ultrasound probe used for imaging an anatomical structure (e.g. an internal organ or bony tissue or cartilage) and using the operating parameter as a guidance for appropriately orienting an x-ray device to generate an image of the same anatomical structure from for example the at least substantially same perspective as the perspective used for generating the ultrasound image. In examples, this is accomplished by using a transformation matrix which is suitable to transform the operating parameter of the ultrasound device into a corresponding control parameter of the x-ray device, or by using an appropriately configured, specifically trained, learnable algorithm such an artificial intelligence algorithm for determining the control parameter of the x-ray device.
