Abstract: Disclosed are joints and methods for forming joints of nonmetallic components such as piping components made from a nonmetallic composite material. The components are joined by an adhesive containing an x-ray absorbing additive for providing a contrasting signal in x-ray inspection of the joint. The joints can be nondestructively tested by positioning the joints relative to an x-ray source and an x-ray detector. The joints and the adhesive therein are then exposed to x-ray radiation from the source of x-ray radiation. The x-ray radiation, having passed from the x-ray source to the x-ray detector, is detected over an area and an x-ray image of the x-ray radiation detected is created. The x-ray image is then read to identify defects in the joint.

Abstract: Embodiments of a method of pore type classification for petrophysical rock typing are disclosed herein. In general, embodiments of the method utilize parameterization of MICP data and/or other petrophysical data for pore type classification. Furthermore, embodiments of the method involve extrapolating, predicting, or propagating the pore type classification to the well log domain. The methods described here are unique in that: they describe the process from sample selection through log-scale prediction; PTGs are defined independently of the original depositional geology; parameters which describe the whole MICP curve shape can be utilized; and objective clustering can be used to remove subjective decisions. In addition, the method exploits the link between MICP data and the petrophysical characteristics of rock samples to derive self-consistent predictions of PTG, porosity, permeability and water saturation.

Abstract: Systems and methods for estimating reservoir productivity as a function of position in a subsurface volume of interest are disclosed. Exemplary implementations may: obtain subsurface data and well data corresponding to a subsurface volume of interest; obtain a parameter model; use the subsurface data and the well data to generate multiple production parameter maps; apply the parameter model to the multiple production parameter maps to generate refined production parameter values; generate multiple refined production parameter graphs; display the multiple refined production parameter graphs; generate one or more user input options; receive a defined well design and the one or more user input options selected by a user to generate limited production parameter values; generate a representation of estimated reservoir productivity as a function of position in the subsurface volume of interest using the defined well design and visual effects; and display the representation.

Abstract: A subterranean coring assembly can include a body having at least one wall that forms a cavity, wherein the cavity has a top end and a bottom end. The subterranean coring assembly can also include a first flow regulating device movably disposed within the cavity toward the top end, where the first flow regulating device is configured to move from a first default position to a first position within the cavity based on first flow characteristics of fluid that flows into the top end of the cavity toward the bottom end of the cavity.

Abstract: Embodiments to enhance recovery of hydrocarbons from a formation by altering wettability at a surface of the formation towards more water-wet are provided. One embodiment comprises providing a formation, providing an aqueous stream for injecting into the formation, adding a reducing agent to the aqueous stream, and injecting the aqueous stream with the reducing agent into the formation to alter a surface charge of the surface of the formation to become more water-wet to enhance recovery of hydrocarbons from the formation. The reducing agent is responsive to characteristics of the formation, characteristics of brine of the formation, and characteristics of hydrocarbons of the formation. The embodiment also comprises injecting a second aqueous stream into the formation after injection of the aqueous stream with the reducing agent. The second aqueous stream comprises surfactant, mobility control agent, the reducing agent, or a combination thereof.

Abstract: Disclosed is a subsea live hydrocarbon fluid retrieval system and method. The system and method include the ability to depressurize the fluid while enacting controlled venting of the gas entrained in the fluid during a controlled ascent to the surface from the seabed. The system and method do not require ancillary equipment at surface for management of gas or pressure. The fluid arrives at surface with minimal gas and pressure.

Abstract: This disclosure relates to a system and method for detecting structural integrity of a well casing. The system may detect casing structural integrity events. The casing structural integrity events may include structural failures of the casing and/or potential structural failures of the casing. The well casing may be drilled and/or otherwise embedded into a geologic structure. The well casing may be subject to geologic forces generated by the geologic structure. Unplanned and/or unexpected forces and/or movement may pose a risk to the structural integrity of the casing. Forces and/or movement of sufficient magnitude may result in damage to and/or destruction of the casing. Damage to and/or destruction of the casing may cause a loss of the natural resources being extracted via the well associated with the well casing, contamination of areas surrounding the well, undesirable surface expression, and/or other negative effects.
