Abstract
A method and apparatus for manipulating fluid, such as measuring bubble point, during drilling or pumping operations including pumping fluid in a borehole through a flow line (200) and drawing fluid from the flow line through an isolation line (232) without substantially dropping pressure of the flow line or without ceasing pumping operations.
Claims21
A method comprising:
- pumping fluid in a borehole through a flow line with a down hole apparatus, the down hole apparatus including a down hole apparatus pump;
- drawing fluid from the flow line through an isolation line without substantially dropping pressure of the flow line, where fluid is pumped through the flow line while fluid is drawn from the flow line;
- manipulating the fluid drawn from the flow line;
- and
- expelling the manipulated fluid.
2 more elements
The method as recited in claim, further comprising opening one or more valves before drawing fluid from the flow line.
An apparatus comprising:
- a down hole apparatus including a flow line pump and a bore hole flow line, the bore hole flow line operatable at a bore hole flow line pressure;
- the flow line pump coupled with the bore hole flow line;
- and
- means for drawing sample fluid from the bore hole flow line while fluid is pumped through the flow line without substantially dropping pressure in the bore hole flow line.
1 more element
An apparatus comprising:
- a down hole apparatus including a flow line pump and a bore hole flow line, the bore hole flow line operatable at a bore hole flow line pressure;
- the flow line pump coupled with the bore hole flow line;
- a measurement module including at least one isolation line and at least one isolation pump;
- at least one isolation pump coupled with the isolation line;
- the isolation line communicatively coupled with the bore hole flow line;
- and
- the isolation line operatable in tandem with the down hole apparatus without substantially affecting the bore hole flow line pressure.
