Abstract: A seismic sensor stake, system and method configured to orientate three seismic 1C sensors orthogonally in the X, Y, and Z directions. The present technology stake is configured to efficiently and effectively convert three independent seismic sensors into a single three seismic sensor unit. Multiple stakes can be inserted into the ground of a geographical area to provide highly accurate seismic survey of subterranean hydrocarbon formations. Each seismic sensor can include a slot that slidable receives a threaded member of a mounting sides of the stake. A retaining nut can secure the seismic sensor in place upon rotation of the sensor. A stake bit can be utilized with an impact hammer to form holes in hard or frozen ground for quick insertion of the stake into the ground.

Abstract: A method for processing seismic data includes receiving, by a seismic data processing system, signals representing seismic data recorded at a remote location. In addition, the method includes receiving, by the seismic data processing system, identification of a sensor via which the signals were acquired. Further, the method includes retrieving, by the seismic data processing system, a sensor transfer function that corresponds to the sensor and relates the motion of the sensor to the signals. The method also includes generating, by the seismic data processing system, based on the sensor transfer function and a reference transfer function, an inverse filter that when applied to the signals changes parameters of the signals to correspond to the reference transfer function. Moreover, the method includes applying, by the seismic data processing system, the inverse filter to the signals to conform the parameters of the signals to the reference transfer function.

Abstract: A seismic survey apparatus includes a body having a longitudinal axis, a first end, a second end opposite the first end, and an inner cavity positioned between the first end and the second end.

Still further, the seismic survey apparatus includes electronic circuitry coupled to the first piezoelectric element. The electronic circuitry is configured to receive and process an output of the first piezoelectric element. The proof mass comprises a power supply configured to provide electrical power to the electronic circuitry.

Abstract: A method includes receiving data indicative of outputs of first and second seismic sensors. The outputs include components corresponding to the detection by the first and second seismic sensors of first and second seismic signals. In addition, the method includes identifying, relative to a first clock in the first seismic sensor, a first time associated with a time of arrival of the first seismic signal at the first seismic sensor, and a second time associated with a time of arrival of the second seismic signal at the first seismic sensor. Further, the method includes identifying, relative to a second clock in the second seismic sensor, a third time associated with a time of arrival of the first seismic signal at the second seismic sensor, and a fourth time associated with a time of arrival of the second seismic signal at the second seismic sensor. Still further, the method includes determining an offset of the first clock relative to the second clock using the first, second, third and fourth times.
