The present invention relates in general to a system to protect and monitor production and non-production oil and gas wells. The present invention provides an oil or gas well and field integrity system for a well which passes through at least one subterranean formation containing pressurized formation fluids. The system comprising at least one oil or gas well located within a designated oil or gas field; and at least one bund wall formed within a target zone of the at least one subterranean formation, each bund extending along at least a portion of a perimeter surrounding the oil or gas field or along at least a portion of a section surrounding one or more oil or gas wells within the oil or gas field to assist in maintaining hydrostatic pressure on at least one side of the bund wall within the target zone thereby reducing the possibility of subsidence within the oil or gas field.

An inerter-based metamaterial for low-frequency vibration attenuation includes a structural matrix material and an inerter array. The inerter array can be embedded within the structural matrix material. The inerter array can include a first inerter cell oriented along a first attenuation axis and a second inerter cell oriented along a second attenuation axis different from the first attenuation axis. The first inerter cell can include a first inerter. The second inerter cell can include a second inerter. The first inerter and the second inerter can be microinerters. The first inerter cell and the second inerter cell can be separated from each other by at least a portion of the matrix material. The first inerter cell and the second inerter cell can each include a first end and a second end and can each be connected to the matrix material at both the first end and the second end.

A smart friction pendulum system including an upper spherical plate and a lower spherical plate each having a sliding surface, a slider positioned between the upper spherical plate and the lower spherical plate, and a plurality of shape memory alloy (SMA) wires each having a first end attached to the upper spherical plate and a second end of attached to the lower spherical plate. The smart friction pendulum system is configured to be attached between the foundation and base mass of a building to preserve the superstructures under the lateral loads. While the lateral loads move the plates side to side, the system dissipates energy by providing friction between sliding material and sliding surface. The SMA wires also absorb the energy when in inelastic reversible phase. The embedded diagonal SMA wires make the whole system recover the initial position fully.
