Abstract
Various implementations described herein are directed to a method of performing a land seismic survey operation. The method may include receiving a first information from a central recording system by a computer system on a seismic truck. The first information describes time and locations of seismic shots being performed in the seismic survey operation. The method may include using a set of rules and the first information to determine a start time for a seismic shot at a next shot location. The method may also include transmitting a second information that describes the next shot location and the start time to the central recording system.

A method for electroforming a nickel-chromium (Ni—Cr) alloy, comprising:
- providing a plating bath containing a solvent, a surfactant, and an ionic liquid including choline chloride, nickel chloride, and chromium chloride, wherein a molar ratio of the choline chloride and chromium chloride ranges from 0.5 to 3.5 and the solvent comprises from 5 to 80 vol. % relative to a mixture of the choline chloride and metal chlorides including both nickel chloride and chromium chlorides;
- and
- electroforming the Ni—Cr alloy onto the mandrel by providing an external supply of current to an anode and a cathode, wherein the mandrel is removed after the Ni—Cr alloy is electroformed.
A method for electroforming a nickel-chromium (Ni—Cr) alloy, comprising:
- providing a plating bath containing a solvent, a surfactant, and an ionic liquid including choline chloride, nickel chloride, and chromium chloride, wherein a molar ratio of the choline chloride and chromium chloride ranges from 0.5 to 3.5 and the solvent comprises from 5 to 80 vol. % relative to a mixture of the choline chloride and metal chlorides including both nickel chloride and chromium chlorides;
- and
- electroforming the Ni—Cr alloy onto the mandrel by providing an external supply of current to an anode and a cathode, wherein the mandrel is removed after the Ni—Cr alloy is electroformed, wherein the electroformed Ni—Cr alloy comprises from 2 to 50 wt % chromium balanced by nickel, and
- wherein the electroformed Ni—Cr alloy is thicker than 125 μm.
