Abstract: Methods and systems for determining a liquid level in a formation between a horizontal segment of an injection wellbore and a horizontal segment of a production wellbore are disclosed. Under shut-in conditions, local temperatures and pressures are determined for each of a plurality of inflow zones along the production wellbore segment. Local profile values are determined based on local shut-in subcool values and local shut-in liquid levels. After flow has resumed, a local liquid level is determined based on the local operating subcool value and the local profile value for that inflow zone. The local profile values may be updated during subsequent shut-ins.

Abstract: Methods and systems for determining a liquid level above a horizontal segment of a wellbore in a formation are disclosed. Local temperatures and pressures are determined for each of a plurality of zones along the wellbore segment. For each zone, a local inflow rate is determined for fluids entering the wellbore from the formation. Based on the local inflow rate, local temperature, and local pressure, a local reservoir pressure is determined, and a local liquid level is determined based on the local reservoir pressure and a pressure associated with an injector wellbore positioned above the horizontal segment.

Abstract: A method of backfilling a subsurface formation that includes forming a mixture tailings from at least two sources that have particles with different size distributions. The water content of the mixture is varied to control the rheology of the mixture. The mixture is injected through one or more pipes into a target location, such as a subsurface formation.

Abstract: A method of organizing a first group of domain objects relating to hydrocarbon management is disclosed. User-defined logic conditions are established. A plurality of the domain objects in the first group of domain objects are selected. It is determined whether any of the selected plurality of domain objects satisfies the logic conditions. A second group of domain objects is created that includes the logic conditions and a list of the domain objects satisfying the logic conditions. An operation command is performed on the second group of domain objects such that the operation command is performed on all domain objects listed in the second group of domain objects.

Abstract: Method for quantitatively assessing connectivity for well pairs at varying frequencies. A time series of measurements (12) is chosen for each of the two wells such that the particular measurements will be sensitive to subsurface connectivity if it exists (11). The two time series may then be pre-processed by resampling to time intervals commensurate with response time between the two wells (13), detrending the measurements (14), and detecting and eliminating spiking noises (15). Then the time series are transformed to the frequency domain where coherence and phase between the two series are compared for varying frequencies (16). This comparison is used to make a determination of connectivity.

Abstract: A system and method for summarizing data corresponding to properties of interest on an unstructured grid that includes active cells and inactive cells on an output surface. An exemplary method comprises identifying an aggregation direction through a region of interest of the unstructured grid and identifying at least one active cell along the aggregation direction.
