    Abstract: Method, devices and systems are provided for measuring deformation in subterranean formations. Such methods include introduction of spaced-apart depth magnetic markers along the longitudinal length of a well bore and measuring the position of each depth marker over time so as to determine deformation of the subterranean formation. In certain embodiments, depth markers comprise rare earth magnets. In further embodiments, orientation of each magnetic bullet is determined over time to determine the change in orientation of each magnetic bullet. Advantages of the methods and devices herein include, but are not limited to, improved accuracy and reliability of deformation measurements and reduced environmental impact due to the avoidance of radioactive markers used by the present invention.

    CPC classification number: G01V1/155

    Abstract: Methods and systems are provided for inducing seismic vibrations into subterranean formations. Seismic transducers may comprise a frame (222), a reaction mass (226), a driver (224), and a baseplate (230). The driver (224) actuates the reaction mass (226), imparting a vibratory energy to the baseplate (230). This vibratory energy is then imparted directly to the ground surface to propagate seismic waves into the formation. These seismic waves are then reflected by subsurface geological features. The reflected seismic waves may then be detected and interpreted by seismic detectors to reveal seismic information representative of the surveyed region. An external dampener (258) may be secured to the baseplate (230), which provide, among other benefits, a damping effect to the baseplate. Advantages include, reduced undesirable baseplate harmonic distortion or "ringing," reduced baseplate decoupling, and reduced seismic noise due to flexure reduction and more uniform baseplate-to-ground conformance. These advantages ultimately translate to improved seismic surveys, having higher formation resolution and reaching greater depths.

    Abstract translation: 提供了将地震振动引入地下地层的方法和系统。 地震换能器可以包括框架（222），反作用块（226），驱动器（224）和基板（230）。 驱动器（224）致动反作用块（226），向基板（230）施加振动能。 然后将该振动能量直接传递到地面，以将地震波传播到地层中。 这些地震波然后被地下地质特征反射。 然后可以通过地震检测器来检测和解释反射的地震波，以揭示代表受测区域的地震信息。 外部阻尼器（258）可以固定到基板（230），其提供除了其它益处对基板的阻尼作用。 优点包括减少不希望的基板谐波失真或“振铃”，减少基板去耦，减少由于挠曲降低引起的地震噪声和更均匀的基板对地面一致性。 这些优点最终转化为改进的地震勘测，具有更高的地层分辨率和更深的深度。

    CPC classification number: G01V1/155

    Abstract: Methods and systems are provided for inducing seismic energy waves in a subterranean formation. More specifically, seismic transducers (200) are provided that incorporate enhanced seismic baseplates (230). In certain embodiments, baseplates (230) comprise certain enhancements (233) such as having a perimeter in the shape of a polygon, such as, a hexagon or an octagon. In other embodiments, the perimeter (233) of the baseplate may take the form of a polygon having n sides, where n is any integer greater than 4. Advantages of such baseplate enhancements include, but are not limited to, a reduction of baseplate harmonics or ringing, enhanced baseplate strength so as to reduce baseplate fatigue or failure, a reduction of baseplate flexure, and a consequent reduction of baseplate weight resulting in a more responsive baseplate. These advantages ultimately translate to improved seismic surveys, having higher resolution of the formations surveyed and resulting in surveys reaching greater depths.

    Abstract: Methods and systems are provided for inducing seismic energy waves in a subterranean formation. More particularly, improved seismic transducers (200) are provided that comprise enhanced baseplates (230). Baseplates (230) are provided that comprise an intermediate plate (230) and a plurality of contact plates (238) secured to the underside of the intermediate plate (230). The contact plates (238) provide a surface area for engagement with the ground surface that is more limited than the lower surface area of the intermediate plate (230). Advantages of such baseplate enhancements include, but are not limited to, a reduction of baseplate harmonics or ringing and enhanced baseplate strength so as to reduce baseplate fatigue or failure, a reduction of baseplate flexure. These advantages ultimately translate to improved seismic surveys, having higher resolution of the formations surveyed and resulting in surveys reaching greater depths.
