    摘要： Techniques for coordinating performance of operations in a well system including receiving, using a central controller, a request to perform a next operation associated with a first operator that includes changing well system equipment from a current equipment state to a target equipment state from a first operator device, determining, using the central controller, whether completion confirmation of a preceding operation associated with a second operator has been received from a second operator device, in response to determining that the completion confirmation of the preceding operation associated with the second operator has not been received, blocking, using the central controller, the first operator from performing the next operation from the first operator device, and in response to determining that the completion confirmation of the preceding operation associated with the second operation has been received, permitting, using the central controller, performance of the next operation associated with the first operator.

    摘要： A method includes gathering data about the well and the deep and tight sandstone reservoir, evaluating a diagenetic rock typing and a flow index of the reservoir using the data, and determining a first set of perforation locations based on the diagenetic rock typing and the flow index. The method also includes calibrating in-situ stresses based on the data and determining a breakdown pressure envelope and optimal perforation directions using the in-situ stresses, maximum horizontal stress direction, formation mechanical properties, and well trajectory. The method further includes narrowing the first set of perforation locations to a second set of perforation locations based on the breakdown pressure envelope, comparing the breakdown pressure envelope of the second set of perforation locations to a maximum downhole pressure to determine a perforation method, and performing a fracturing operation on the well using the second set of perforation locations, the perforation method, and the optimal perforation directions.

    摘要： A fluid end assembly made of a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a plurality of individual components joined together in a row. Two sets of fasteners are used to secure various components of each fluid end section together. When the fluid end section is assembled, a first set of fasteners is in a spaced relationship with and faces a second set of fasteners. At least one component making up the multi-piece fluid end section is configured to have a plurality of stay rods attached thereto. The stay rods interconnect the fluid end assembly and a power end assembly.
