Abstract: Method, source array and source element that generate seismic waves. The source element includes an enclosure having an opening covered by a piston; a local supply accumulator fluidly communicating with an interior of the enclosure, a pressure of the fluid inside the local supply accumulator being larger than a pressure of the fluid inside the enclosure; a local supply valve located between the local supply accumulator and the enclosure and configured to control a flow of the fluid from the local supply accumulator to the interior of the enclosure; and a controller configured to control the local supply valve such that the pressure inside the enclosure does not fall below a first preset value based upon an ambient pressure of the enclosure while seismic waves are generated.

Abstract: The invention is an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. Preferably a foot is arranged on the bottom end of the rod or piston for contact with the ground and by engaging the grid of motors to push down against the ground in a rapid progression, acoustic energy is created and delivered into the ground for geophones to sense and record. However, the rapid progression of pulses or sweep of seismic energy is delivered in a distinctive fashion as compared to a conventional upsweep or downsweep and the distinctiveness is also achieved by creating a designed cadence or timing such that each pulse in a series of pulses is not delivered in a regular timing. Several similar seismic sources may be employed where each is provided with its own distinctive series of pulses such that each may be identified within the data record and source separation from a number of seismic sources may be accomplished.

Abstract: Tunable down-hole stimulation systems feature closed-loop control of pumps and tunable down-hole stimulators. Stimulators generate and hydraulically transmit broad vibration spectra tuned for resonance excitation and fracturing of geologic materials adjacent to the wellbore. Feedback data for controlling stimulation includes backscatter vibration originating in stimulated geologic material and detected at the stimulator(s). For initial fracturing with relatively large particle sizes, the power spectral density (PSD) of each stimulator output is down-shifted toward the lower resonant frequencies of large particles. As fracturing proceeds to smaller (proppant-sized) fragments having higher resonant frequencies, backscatter vibration guides progressive up-shifting of stimulator PSD to higher vibration frequencies. Stimulator power requirements are minimized by concentrating vibration energy efficiently in frequency bands to which geologic materials are most sensitive at every stage of stimulation. Geologic fragmentation efficiency is thus optimized, with inherent potential for plain-water fracs completed with self-generated proppant.
Abstract translation: 可调谐的井下刺激系统具有泵和可调谐井下刺激器的闭环控制。 刺激器产生和液压传输调谐为与井眼相邻的地质材料的共振激发和压裂的宽振动光谱。 用于控制刺激的反馈数据包括源自刺激地质材料并在刺激器处检测的反向散射振动。 对于具有相对较大粒度的初始压裂，每个刺激器输出的功率谱密度（PSD）向大颗粒的较低共振频率向下移动。 随着压裂进行到具有较高谐振频率的较小（支撑剂大小）碎片，反向散射振动引导刺激器PSD的逐渐向上移位到更高的振动频率。 通过将振动能量有效地集中在地质材料在每个刺激阶段最为敏感的频带中，可以最大限度地提高刺激能力。 因此，优化了地质碎裂效率，并利用自生产的支撑剂完成了纯水裂缝的固有潜力。

Abstract: Aspects described herein relate to an electromagnetic seismic vibrator (EMSV) architecture that provide wide frequency range operation, ground force application with high fidelity, and low environmental impact. The EMSV architecture can include a base member that can support a force coil and mitigate electrical heating due, at least in part, to spurious currents. The EMSV architecture can include means for restricting movement of a reaction member included in the EMSV architecture relative to the base member. Such means can permit mitigation of damage of the EMSV architecture in scenarios in which control of the EMSV architecture may fail.
