A method and a computer-readable storage medium are also disclosed.

In some embodiments, apparatus and systems, as well as methods, may operate to measure formation fluid and obtain data, the data having measurement levels that vary over a parameter. The data is grouped in one or more categories, each category having data falling within a range, and the grouped data is analyzed as a function of the parameter. In some embodiments, the grouped data is used to identify at least one fluid type of the formation fluid using the grouped data.

A method and a device are proposed for determining the type of fluid in a fluid mass in an object. X-ray attenuation data is supplied from one or a plurality of X-ray recordings of an object area including the fluid mass in the object, which were acquired with at least two different X-ray spectra or detector weightings. The X-ray attenuation data is used to determine values for effective atomic number and density for the fluid mass and average these to obtain a mean value for effective atomic number and density for the fluid mass. Comparison data is also supplied, which indicates fluctuation ranges for combinations of effective atomic number and density for different types of fluid. The mean values for effective atomic number and density of the fluid mass are compared with the comparison data to determine the fluctuation range and thereby the type of fluid, into which the two mean values fall. The method and associated device can be used to determine the type of fluid in a fluid mass in an object in a reliable and unambiguous manner.

The invention relates to a method and a device for evaluating sand-blocking performance of a sieve with a sand-prevention sieve tube. The method comprises the following steps of: putting the sieve with the sand-prevention sieve tube to be evaluated on the lower part of a simulated formation which is used for simulating a well-bore surrounding rock formation in the evaluation device; pumping a high-pressure fluid into the device; performing data acquisition by using a flowmeter and a sand collecting bucket which are arranged at an outlet at the lower end of the evaluation device; and analyzing the acquired data to evaluate the sand-blocking performance of the sieve with the sand-prevention sieve tube. The evaluation device comprises a cylinder body (102), the simulated formation (101), a hydraulic power device (103), a pressure sensor (104-1) on the upper part of the cylinder body, a pressure sensor (104-2) on the middle part of the cylinder body, a pressure sensor (104-3) on the lower part of the cylinder body, the flowmeter (105), the sand collecting bucket (106), a data acquisition device (107) and the sieve (108) with the sand-prevention sieve tube to be evaluated. The method and the device can quickly evaluate the sand-blocking performance of the sieve with the sand-prevention sieve tube in different working environments, determine a suitable sieve combination with the sand-prevention sieve tube, and improve the sand prevention efficiency and prolong the service life of the sand-prevention sieve tube in an oil-gas well by simulating various oil-gas well working environments with different production pressure differences and different fluid types of the sand-prevention sieve tube.

An adjustable fluid type lens system is provided that allows e.g. ultrasound imaging through the lens during adjustment of the lens. The lens includes a container enclosing two immiscible fluids, e.g. water and oil, being in contact with each other at an interface. Incoming waves are then refracted at this interface. The shape of the interface, and thereby the refraction property, is adjustable by adjusting a voltage applied to the lens. The two fluids are selected such that they together exhibit a mechanical damping which is critical or near critical. A control circuit generates the electric voltage for adjusting the refraction from one value to another, the control circuit being arranged to change the electric voltage such that a rate of voltage change is limited to avoid oscillation of the interface, thereby adjusting refraction of incoming waves at the interface in a continuous manner. This makes it possible to use the lens while it is during adjustment from one refraction value to another, since the interface shape will at all time during the adjustment have a controlled shape. The voltage can be either a continuous voltage or a discrete stepwise (digital) voltage which is just controlled with respect to step size and temporal extension of the steps. The lens system has a number of applications e.g. within the medical field, e.g. for ‘on the fly’ high speed ultrasound imaging, or for ultrasound ablation applications where ablation can be performed during adjustment of the lens to follow a pre-defined trajectory.

A fluid dispenser is disclosed where a backoff distance is determined and implemented to prevent leakage while dispensing sequentially an accurate, precise amount of fluid substantially independent of the fluid remaining in a syringe-type dispenser. The fluid characteristics of the fluid, e.g. viscosity, surface tension, etc. affect the backoff distance that may be determined heuristically for fluid type, amount of fluid remaining in the syringe and amount to be dispensed. Once the fluid characteristics are known, the dispensing may be accomplished automatically with a processor loading new drive and backoff steps to a motor controller.
