A downhole tool is positioned in a borehole of a geological formation at a given depth. A formation property is determined at the given depth. The positioning and determining is repeated to form data points of a data set indicative of formation properties at various depths in the borehole. One or more outlier data points is removed from the data set based on first gradients to form an updated data set. One or more properties associated with a reservoir compartment are determined based on second respective gradients associated with the updated data set.

A system and methods for petro-steering methodologies are provided. An exemplary method obtains rock fabric data, and integrate rock fabric data with dynamic productivity data to identify patterns between the rock fabric data and dynamic productivity data. Gas rates and steering values are predicted across UBCT wells based on the patterns.

A treatment system comprises a treatment bladder associated with a volume of a tubing-casing annulus of a wellhead system to be treated. The treatment bladder contains a treatment fluid and is at an elevated pressure. The treatment bladder is coupled to the tubing-casing annulus utilizing a fluid conduit through a lower fluid junction. The fluid conduit permits two-way fluid communication between the treatment bladder and the tubing-casing annulus. A method for treating the tubing-casing annulus includes coupling the treatment bladder containing the treatment fluid of the treatment system to the tubing-casing annulus of the wellhead system using the fluid conduit, establishing two-way fluid communication between the tubing-casing annulus and the treatment bladder though the fluid conduit, halting fluid communication though the fluid conduit, and decoupling the treatment bladder from the tubing-casing annulus.

Apparatuses, systems, and methods for detecting and monitoring hydrogen sulfide in a natural gas stream are disclosed herein. The apparatuses typically include a body comprising at least a first wall, a second wall spaced from the first wall, and a third wall coupled to the first wall and the second wall, wherein the first wall, the second wall, and the third wall define a chamber. The apparatus also typically includes an inlet conduit configured to receive a gaseous stream comprising natural gas and provide the gaseous stream to the chamber; a pressure valve coupled to the exit port, the pressure valve being configured to actuate to release an amount of gas; and an indicator at least partially disposed in the chamber, wherein the indicator comprises a reactive material that is adapted to produce a visual change in the presence of hydrogen sulfide.

Fluid holdups within a downhole sampling tool are identified by comparing high- and low-resolution measurements of fluid samples.

A method and system can obtain real time property measurements of a fluid comprising a formation fluid downhole, real time measurements of an amount of an interactive component of the fluid downhole, and real time measurements of an amount of a non-interactive component of the fluid downhole. The method and system further includes determining a total amount of the interactive component in the fluid or a contamination level of the formation fluid at a time of interest based on the real time property measurements of the fluid downhole and the real time measurements of the amounts of the interactive component and non-interactive component downhole. The real time measurements of the amount of the interactive component downhole are real time measurements of the amount of the interactive component in its free form downhole, and the property can be scaled with the contamination level.

Systems and methods for measuring phase flow rates of a multiphase production fluid are provided where a fluidic isolation chamber expands volumetrically in response to fluid pressure from a diverted multiphase production fluid. A pressure-regulating actuator regulates fluid pressure upstream of the fluidic isolation chamber and an upstream fluidic pressure sensor generates an upstream fluidic pressure signal. A fluidic control and analysis unit is configured to communicate with the upstream pressure sensor and the isolation chamber actuator to maintain fluidic pressure upstream of the fluidic isolation chamber as the multiphase production fluid is diverted to the fluidic isolation chamber. The unit generates a total flow rate Q.sub.TOT as a function of chamber filling time and volumetric expansion and communicates with the fluidic phase detector to generate a relative occupancy indicator I for a target phase of the multiphase production fluid in the fluidic isolation chamber. A flow rate Q.sub.P for the target phase is generated as a function of the total flow rate Q.sub.TOT and the relative occupancy indicator I.

Systems and methods for developing hydrocarbon reservoirs based on constrained natural fracture parameters. A natural fracture modeling is generated for a reservoir, an initial set of fracture model parameters is determined, and a fracture model optimization is conducted to determine an optimized set of fracture model parameters. The optimized set of fracture model parameters are used as a basis for modeling the reservoir, and the modeling is used to generate a simulation of the reservoir.

An x-ray-based borehole fluid evaluation tool for evaluating the characteristics of a fluid located external to said tool in a borehole using x-ray backscatter imaging is disclosed, the tool including at least an x-ray source; a radiation shield to define the output faun of the produced x-rays into the borehole fluid outside of the tool housing; at least one collimated imaging detector to record x-ray backscatter images; sonde-dependent electronics; and a plurality of tool logic electronics and power supply units. A method of using an x-ray-based borehole fluid evaluation tool to evaluate the characteristics of a fluid through x-ray backscatter imaging is also disclosed, the method including at least producing x-rays in a shaped output; measuring the intensity of backscatter x-rays returning from the fluid to each pixel of one or more array imaging detectors; and converting intensity data from said pixels into characteristics of the wellbore fluids.
