Abstract: A sample catching system for cleaning a drilling fluid in a drilling operation includes a first line having a first entrance valve configured to allow the drilling fluid to flow into the first line, a first chemical sensor for measuring the amount of hydrogen sulfide of the drilling fluid in the first line, and a first sample catch valve configured to allow the drilling fluid to flow out of the first line. The system also includes a second line having a second entrance valve configured to allow the drilling fluid to flow into the second line, a sample catch pump, and a controller configured to determine the amount of hydrogen sulfide is above a predetermined threshold value, and open the second entrance valve to divert drilling fluid intake from the first line to the second line, and close the first entrance valve to stop the drilling fluid from entering the first line.

Abstract: An auto cleaning system for cleaning a drilling fluid in a drilling operation includes a first line, a second line, an auto clean pump operatively connected to the first line and the second line, and an electromagnetic device around at least a portion of the first line, wherein the electromagnetic device is energized when the drilling fluid is passing through the first line. The auto clean pump is configured to receive the drilling fluid from the first line or the second line and remove metal particles from the drilling fluid. The system also includes a controller configured to determine a pressure difference in a line, at least partially open a valve to divert drilling fluid intake from one line the other, and close the first entrance valve to stop the drilling fluid from entering the first line.

Abstract: A whipstock system and methods are disclosed, including a whipstock body, a control unit mounted on or in the whipstock body, the control unit comprising transmitters and receivers operable to receive commands from an external source, activatable components mounted on or in the whipstock body, and a hydraulic system in the whipstock body, the hydraulic system in communication with the control unit, the hydraulic system including at last one hydraulic power unit operable to repeatedly activate and de-activate the activatable components.

Abstract: A system for cleaning a wellbore can include a bottom hole assembly that is designed to be run downhole into a wellbore after the wellbore has been drilled and before the wellbore has been cleaned. A control sub-assembly is mounted on and carried by the bottom hole assembly. The control sub-assembly is designed to be positioned within the wellbore. Multiple cleaning sub-assemblies are interchangeably mounted on and carried by the bottom hole assembly. Each cleaning sub-assembly is designed to be positioned within the wellbore. The multiple cleaning sub-assemblies include at least two of the following sub-assemblies: a scraping sub-assembly that scrapes an interior of the wellbore, a brushing sub-assembly that brushes the interior of the wellbore, or a magnetic sub-assembly that magnetically captures debris within the wellbore.

Abstract: The method comprising the steps of mixing an amount of scavenger into a drilling mud to produce a scavenger-containing drilling mud such that the scavenger-containing drilling mud has a scavenging capacity, wherein the drilling mud is at a target pH, and introducing the scavenger-containing drilling mud into the wellbore during drilling operations, where the scavenger-containing drilling mud is operable to work with a drill bit to drill the wellbore, where the amount of scavenger in the scavenger-containing drilling mud is operable to irreversibly react with hydrogen sulfide present in the drilling mud to produce a scavenged hydrogen sulfide.

Abstract: A pumping system includes a primary suction tank including a first pressure sensor operatively connected to a first portable suction control for measuring a first pressure of a fluid coming from the primary suction tank, and a first flow meter operatively connected to the first portable suction control for measuring a first flow rate of the fluid coming from the primary suction tank, wherein an output of the primary suction tank is controlled by a first valve, a secondary suction tank, a rig pump operatively connected to the primary suction tank, and the secondary suction tank, and a rig stand pipe connected to a drilling well, and a controller operatively connected to the first portable suction control, the first valve, and a second flow meter configured to measure a second flow rate of the fluid coming out of the rig pump.
