Abstract

A manifold directs the flow of drilling mud from a drilling rig. A longitudinal tubular body has a first end and a second end, such that the longitudinal tubular body is supported by at least two supports of a platform. The platform can support a monorail that is parallel to the longitudinal tubular body, so that it is five feet of the longitudinal tubular body. The longitudinal tubular body can have at least three side directed input ports so that the ports are adapted to receive a mud pipe for attachment. Each of the three side-directed input ports can face substantially towards and above the monorail to provide unobstructed lateral attachment of a mud pipe to the longitudinal tubular body.

Claims

1. A manifold for directing the flow of drilling mud from a drilling rig, the manifold comprising:

a longitudinal tubular body having a first end and a second end, the longitudinal tubular body is supported by at least two supports of a platform;

a monorail that is parallel to the longitudinal tubular body, the monorail also supported by the platform such that the monorail is within five feet of the longitudinal tubular body and arranged parallel to a longitudinal axis of the longitudinal tubular body; and

at least two side-directed input ports in the longitudinal tubular body adapted to receive a mud pipe for attachment, wherein each of the at least two side-directed input ports faces substantially towards and above the monorail to provide unobstructed lateral attachment of a mud pipe.

2. The manifold of claim 1, further comprising nozzles, one corresponding to each of the at least two side-directed input ports, each nozzle directed internal to the longitudinal tubular body and towards the first end.

3. The manifold of claim 1, further comprising a slidable jack placed on top of the monorail, to further support and raise a mud pipe.

4. The manifold of claim 1, wherein the second end is raised above the first end to orient the longitudinal tubular body above 20°

of horizontal.

5. The manifold of claim 1 further comprising a valve for opening the second end for flow.

6. The manifold of claim 1, further comprising a flex-hose attached to the first end or the second end.

7. The manifold of claim 1, wherein each input port has a flange having holes for bolting onto a corresponding flange of a mud pipe.

8. The manifold of claim 1, wherein the second end has a flange having holes for bolting onto a corresponding flange of a second manifold.

9. The manifold of claim 1, further comprising a flex-hose extending an end of the longitudinal tubular body, wherein the end is selected from the group consisting of the first end and the second end.

10. A manifold for directing flow of drilling mud from a drilling rig, the manifold comprising:

a longitudinal body having a first support and a second support, wherein the longitudinal body has at least two sideways extending pipes that extend in parallel to each other;

wherein the longitudinal body has a downstream terminal end located at an end-point of the longitudinal body and an upstream terminal end located at an end-point of the longitudinal body opposite to the downstream terminal end, wherein each of the downstream and upstream terminal ends has a flange with through-holes for bolting additional conduits to such downstream and upstream terminal ends;

wherein the longitudinal body has at least two monorail supports extending therefrom to support a monorail, and the monorail is substantially below the at least two sideways extending pipes and the at least two sideways extending pipes support a monorail to be substantially parallel to a longitudinal axis of the longitudinal body.

11. The manifold of claim 10, wherein the monorail is rigidly held within five feet of the sideways extending pipe.

12. The manifold of claim 10, wherein the monorail supports a slidable jack.

13. The manifold of claim 10, further comprising nozzles, one corresponding to each sideways extending pipes, each nozzle directed internal to the longitudinal body and towards a first end of the longitudinal body.

14. The manifold of claim 10, further comprising a slidable jack placed on top of the monorail, to further support and raise a mud pipe.

15. The manifold of claim 10, wherein the upstream terminal end is raised above the downstream terminal end to tilt the longitudinal body above 20°

of horizontal.

16. The manifold of claim 15 further comprising a valve for opening the second end for flow.

17. The manifold of claim 10, further comprising a flex-hose attached to a the upstream terminal end or the downstream terminal end of the longitudinal body.

18. The manifold of claim 10, wherein each of the sideways extending pipes has a flange having holes for bolting onto a corresponding flange of a mud pipe.
