A method and systems for sand control in wells are described in examples. An example uses a prepack screen assembly comprising an inner screen comprising openings having an inner size and an outer screen comprising openings having an outer size. Packing material is disposed between the inner screen and the outer screen comprising pores with a pore size that is selected based, at least in part, on the outer size, the inner size, or both.

Material control to prevent well plugging

A system and method is provided for enhancing hydrocarbon production. The method and system involve geochemistry analysis and include multiply substituted isotopologue and position specific isotope geochemistry for at least one hydrocarbon compound of interest associated with free gas and sorbed gas. The method and system involve using clumped isotope and position specific isotope signatures to enhance monitoring of well and stimulation performance.

Method and systems for modeling fractures in quasi-brittle materials are provided. An exemplary method included generating a model that incorporates a unified creep-plasticity (UCP) representation into a constitutive model for a ductile rock. The model may be used in a finite element analysis to model hydraulic fractures in the ductile rock.

Methods and systems for making decisions related to the operation of a hydrocarbon well include characterizing effective production capacity of a reservoir over space and time based at least in part on a reservoir potential and a near-well capacity; determining an optimized well potential over space and time relative to the characterized effective production capacity using a well model of a simulated well accessing the reservoir, which may be determined based at least in part on an objective function that considers at least one of a plurality of decision-making factors, such as one or more of operations costs, operational risks, and modeled production rates over the life of the well; and determining at least one well operating plan component that can be incorporated into a well operating plan to provide the optimized well potential in a well accessing the reservoir.

Optimizing well operating plans

A method for modeling a reservoir response in a subsurface system is provided. The subsurface system has at least one subsurface feature. Preferably, the subsurface system comprises a hydrocarbon reservoir. The method includes defining physical boundaries for the subsurface system, and locating the at least one subsurface feature within the physical boundaries. The method also includes creating a finite element mesh within the physical boundaries. The finite element mesh may have elements that cross the at least one subsurface feature such that the subsurface feature intersects elements in the mesh. A computer-based numerical simulation is then performed wherein the effects of the subsurface feature are recognized in the response. The reservoir response may be, for example, pore pressure or displacement at a given location within the physical boundaries.
