Abstract: Tools and methods are used to determine the oil, water, and solids volume fractions in a drilling fluid at the rig site. The volume fractions can be determined in-line with returned drilling fluid by using an NMR magnet and a flow line or sample chamber that receives a fluid sample and loads it into the NMR magnet. Using an RF probe, spectrometer, and computing device, data processing and interpretation of NMR data from the spectrometer is performed, while also raising a flag when iron contamination exceeds a predefined threshold.

Abstract: A technique facilitates control over packers and/or other well tools actuated downhole. The technique utilizes a valve connectable into a well string. The valve is shiftable between a plurality of modes so as to control flow of fluid in a downhole environment. Additionally, an actuator system is connectable into the well string and operatively coupled with the valve. The actuator system is electronically controlled to cause the valve to shift to a desired mode of the plurality of modes. This approach enables electronic control over the actuation of specific downhole tools, e.g. packers, and/or other well related operations.

Abstract: A technique facilitates pressure application downhole by locking a ball in place to prevent it from unseating even if the pressure is bled off. A ball seat is constructed with a locking feature for effectively capturing and retaining the ball once the ball is seated in the ball seat under sufficient pressure. According to an embodiment, the ball seat may be mounted at a desired position along an internal flow passage of a well string component. The ball seat comprises a throat section which is formed of a ductile material arranged in a suitable structure to enable a desired deformation upon receiving the ball under sufficient pressure. As the ball is pressed into the throat section, the material of the throat section deforms and partially springs back to resist movement of the ball in the uphole direction, thus capturing the ball in both the uphole direction and the downhole direction.

Abstract: The effectiveness of expansive cement systems may be diluted when, during a well cementing operation, commingling takes place between the cement slurry and a spacer fluid, a drilling fluid, or both. Incorporating expansive agents in the spacer fluid or drilling fluid may reduce or negate the loss of expansion at the cement slurry/spacer interface or the cement slurry/drilling fluid interface, thereby promoting zonal isolation throughout the cemented interval.

Abstract: Generating a virtual core includes obtaining acquired data for a region of interest, determining a rock type of the region of interest, obtaining a selection of modules based on the rock type, and generating, using the acquired data and an interpolator from the modules, a wellbore image of the region of interest.

Further, using a quantifier from the plurality of modules, a core characterization of the region of interest is determined. The core characterization describes an integration of wellbore data types. Using the core characterization and the wellbore image, a digital core construction of the region of interest is generated. The digital core construction describes subterranean formation properties of the region of interest.
