Abstract: Systems and methods for using stratigraphic heat maps to steer a well being drilled. Data from one or more offset wells can be provided to a computer system and used with data from a well being drilled to generate one or more stratigraphic heat maps during the drilling of the subject well. The stratigraphic heat maps can be displayed and used to determine the location of the wellbore relative to one or more geological formations, including one or more target formations or within a target formation. Based on the use of the heat maps and the location of the wellbore relative to a target, the drill plan can be adjusted or updated and/or one or more drilling parameters or operations may be adjusted to drill the wellbore, such as to drill the wellbore to the target or to maximize the length of the wellbore within a target zone.

Abstract: Stratigraphic analysis includes determining misfit values between stratigraphic vertical depth of an offset wellbore, SVDow and measured depth of a subject wellbore. A likelihood that the target measured depth is equal to or within a tolerance of stratigraphic vertical depth of the subject wellbore, SVDsw, for sequences of stratigraphic vertical depth is calculated. A probability weighted average and an uncertainty that the target measured depth for the subject wellbore, TMDsw, is equal to or within a tolerance of stratigraphic vertical depth of the subject wellbore, is calculated. A continuous probability function over a range of measured depth that the target measured depth for the subject wellbore, TMDsw, is equal to or within a tolerance of stratigraphic vertical depth of the subject wellbore, SVDsw, is calculated.

Abstract: A voided floor panel is provided. The voided floor panel includes a pre-cast dome, strands, reinforcing bars, and a slab. The pre-cast dome includes a flange portion, stem portions, and joint portions. The strands are pre-tensioned. The reinforcing bars are inserted through rebar block-outs of the pre-cast dome. The joint portions, the strands, and the reinforcing bars are cast within the slab. The strands improve a resistance of the slab to flexure. The joint portions improve a vertical shear resistance between the slab and the pre-cast dome. The joint portions may include corrugated dovetails for further improving a horizontal shear resistance between the slab and the pre-cast dome.

Abstract: When a user of an interface system defines a workflow, the interface system transmits a notification to a user that is to perform the first step of the workflow. When the user requests to initiate the step of the workflow, the interface system creates a transaction for the workflow step. The user signs the transaction using a cryptographic key pair. The interface system receives the signed transaction and verifies the signature. Once the signature is verified, the step can be performed. The interface system forwards the transaction to a data storage system for storing. For performing the next step in the workflow, the data storage system identifies the user that is to perform the next workflow step. The data storage system creates a notification that identifies the user and the notification is provided to the user. The process repeats until each step of the workflow is performed.

Abstract: Movable pipe supports are described herein. A movable pipe support can include a pipe support apparatus body having a slot sized to accommodate a first end of a lever arm positioned such that it extends through the slot, a pipe support structure attached to the first end of the lever arm and having an outer surface for contacting an outer surface of the pipe, and a pivot mechanism to allow the outer surface of the pipe support structure to continue to be in contact with the outer surface of the pipe while the pivot mechanism moves the outer surface of the pipe support structure along the outer surface of the pipe.

Abstract: Pipe supports are described herein. A pipe support can include a first elongated body having a first top surface for supporting a pipe having a pipe surface, a second elongated body having a second top surface for supporting the pipe and a support structure slidably coupled to the first elongated body and to the second elongated body such that the first top surface or the second top surface is in contact with the pipe surface when the other of the first top surface and the second top surface is not in contact with the pipe surface.

Abstract: A data integrity system generates a transaction signature associated with a transaction based on transaction data received from a data producer. The transaction signature is unique to the transaction and is generated by applying a hash function to the transaction data. When the transaction data is to be transmitted to a data consumer, the data integrity system redacts the transaction data based on permission information associated with the data consumer and transmits the redacted transaction data to the data consumer. To enable the data consumer to verify the integrity of the received data, the data integrity system also transmits a cryptographic assurance that includes at least the transaction signature associated with the transaction. The data consumer verifies the integrity of the received data by independently generating a transaction signature based on the redacted transaction data and matching the independently generated signature with the transaction signature in the cryptographic assurance.
