Systems and methods are provided for determining ion concentration of a fluid downhole using a polymer matrix packaged in a cartridge. An example method can include disposing a cartridge within a flow path of a sensor. The cartridge includes a bracket; a retainer formed of a porous material having pores sized to allow a fluid to flow therethrough; and a substrate comprising a polymer matrix embedded with an ion-indicator, the substrate configured to interact with the fluid and to modify an optical characteristic of the substrate according to an ion concentration of the fluid. The method further includes illuminating the substrate; detecting a change in an optical characteristic of the substrate, the change indicative of the ion concentration of the fluid; and determining the ion concentration of the fluid.

A fluid sampling tool may include a fluid characterization device consisting of a densitometer, a viscometer, or a vibrating element, or a combination thereof and a polymer disposed in or around the fluid characterization device, wherein the polymer volume, density, or viscosity changes with an ionic stimulus. The fluid characterization device may be located within a bypass flow line of the sampling tool. A method of measuring pH and a method of monitoring at least two analytes at the same time using the fluid characterization devices are also discussed.

Measurement of water chemistry by altering the resonant frequency of a vibrating element with hydrophilic hydrogels

Wellbore equipment used in oil and gas operations can be negatively affected by corrosive fluids. Coatings can be applied to the equipment to help protect the equipment. A field test can be used at a wellsite to ensure the coating is effective. Due to the HSE risks of the corrosive fluids, a proxy fluid can be used instead. The proxy fluid can have similar chemical or physical properties and simulate the corrosive fluid that is anticipated to be present in the wellbore. The wellbore equipment that is coated can be sealed to create a containment area where an initial concentration of the proxy fluid is introduced into the containment area for a period of time. A final concentration of the proxy fluid can be measured after the period of time has elapsed. By calculating the percent change of the proxy fluid, the effectiveness of the coating can be determined.

The system can further generate data useable to determine at least one status of the tubular and at least one status of a cement layer. The cement layer can be positioned between the tubular and a subterranean formation surrounding the wellbore.

The present disclosure relates to systems and methods of determining a wellbore position in a subterranean formation by using gravity sensors to detect a gravity anomaly related to a presence of the wellbore, contents within the wellbore, and or fluid flowing through an interface of the wellbore. A model of the subterranean formation predicts a gravity profile, including the gravity anomaly, and the model may be constrained with a depth of the gravity anomaly as calculated with at least one of a known dimension or a known gravitational field change related to the gravity anomaly. The wellbore position is determined within the model by changing model input data until the gravity profile converges with the gravity anomaly.

Described herein are systems and techniques for monitoring for monitoring and evaluating conditions associated with a wellbore and wellbore operations that use neural operators instead of computationally intensive iterative differential equations. Such systems and techniques allow for determinations to be made as operations associated with a wellbore are performed. Instead of having to wait for computationally intensive tasks to be performed or take risks of proceeding with a wellbore operation without real-time evaluations being performed, these wellbore operations may be continued while determinations are timely made, thus improving operation of computing systems that perform evaluations and that make decisions regarding safely and efficiently performing wellbore operations such as drilling a wellbore, cementing wellbore casings in place, or injecting fluids into formations of the Earth.
