Abstract: A global fluid identity repository is used to maintain and manage fluid characterization data for various fluids utilized in the oil & gas industry, e.g., reservoir fluids within subsurface formations. Tracking and notification services may be utilized to track changes made to a global fluid identity, e.g., changes in fluid sample and/or experiment data for a fluid, and automatically generate notifications when downstream data such as fluid models and/or simulation results become stale as a result of these changes.

Abstract: The disclosure presents a technique to generate a fracture model using a differential stress map and model inputs. The technique simulates the fracture model using fracture fronts, initiated at perforations of a perforation stage of a hydraulic fracturing (HF) wellbore. Each fracture front is evaluated using a propagation step of a fracture model process. Using the relative differential stress states, a fracture pattern is composited to the fracture model. At each propagation step, the total energy available from the simulated HF fluid being pumped into the wellbore location is reduced by the amount necessary to generate the computed fractures. Once the remaining energy is reduced to a level where no further fractures can be created, or if a map boundary is encountered, the fracture model process terminates. The generated fracture model can be communicated to update HF job plans, wellbore placements, and other uses of the fracture model.

Abstract: The present disclosure provides a method based on consistency of a distribution feature of checking-validation data for establishing a hydrological model. The method includes: S1: proposing an idea of discrete checking of data for a hydrological process model according to S11-S12; S2: using an MDUPLEX method to allocate an original runoff data set D to a checking set C and a validation set E according to S21-S28; and S3: checking and validating the model according to S31-S32, determining a model parameter, and establishing the hydrological process model. The present disclosure guarantees consistency of performance of the hydrological process model during checking and validation periods by means of discrete sampling, so as to improve effectiveness of the hydrological process model and stability of engineering application.

A method of designing services for wellbores includes calibrating a loss circulation model with input comprising wellbore state to update the loss circulation model with formation loss zone characteristics; applying the loss circulation model to output at least a prediction of loss rate; and designing a wellbore service at least partially based on the prediction of the loss rate.

Abstract: The present disclosure is related to prospecting hydrocarbon accumulations based on the collective concentration of monocyclic aromatic compounds in water samples collected from geological formations. For example, one or more embodiments are related to a method that includes screening one or more geological formation water samples for contamination by comparing an internal distribution of monocyclic aromatic compounds of the one or more geological formation water samples to a reference monocyclic aromatic compound distribution. The method can also include determining a prospect zone associated with a non-contaminated geological formation water sample from the one or more geological formation water samples. A location of the prospect zone can be based on a cumulative monocyclic aromatic compound concentration of the non-contaminated geological formation water sample. Also, the prospect zone can refine a hydrocarbon-water contact location of a known hydrocarbon accumulation.
