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.

First claim

What is claimed is:

1. 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.

2. The method according to claim 1 , wherein the anode is an insoluble anode.

3. The method according to claim 1 , wherein the anode is a Ni—Cr alloy anode, a Ni anode, or a Cr anode.

4. The method according of claim 1 further comprising pre-treating the mandrel prior to electroforming the Ni—Cr alloy.

5. The method according to claim 1 , wherein a protective coating is applied on the electroformed Ni—Cr alloy.

6. The method according to claim 1 , wherein the current is a direct current or an alternating current.

7. The method according to claim 1 , wherein the solvent is a polar protic solvent.

8. The method according of claim 1 , wherein the solvent is a polar aprotic solvent.

9. The method according of claim 1 , wherein the solvent is chosen from one or more of formic acid, citric acid, isopropanol (IPA), water, acetic acid, and ethylene glycol.

10. The method according to claim 1 , wherein the surfactant is an anionic, a cationic, or an amphoteric surfactant.

11. The method according to claim 1 , wherein the surfactant is either sodium dodecyl surfate, fluorosurfactants, cetyl trimethylammonium bromide (CTAB), or cetyl trimethylammonium chloride (CTAC).

12. The method according to claim 1 , wherein the electroformed Ni—Cr alloy comprises from 2 to 50 wt % chromium balanced by nickel.

13. The method according to claim 1 , wherein the electroformed Ni—Cr alloy comprises from 8 to 20 wt % chromium balanced by nickel.

14. The method according to claim 1 , wherein the electroformed Ni—Cr alloy is thicker than 125 μm.

15. 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.
