Abstract
The present disclosure is for a tool and a method using or making the tool for detection of production or formation water in drilling fluid. The tool includes a sampling chamber to receive a bypass line from a flow line at a well site. The tool further includes spectroscopy components to perform spectroscopy of the drilling fluid bypassed from a flow line into the bypass line. Processing components are provided in the tool to process spectra from the spectroscopy of the drilling fluid and to generate data associated with at least identification formation or production water in the drilling fluid. The tool includes a communication module to transmit the data externally from the tool.
Claims20
A tool (106) for detection of formation or production water in drilling fluid characterized by:
- a sampling chamber (158) to receive a bypass line (152) from a flow line (116) at a well site;
- at least one spectroscopy component (164) to perform spectroscopy of the drilling fluid bypassed from the flow line into the bypass line;
- at least one processing component (172) to process spectra from the spectroscopy of the drilling fluid and to generate data associated with at least identification formation or production water in the drilling fluid;
- and
- a communication module (186) to transmit the data externally from the tool.
A method (400;
- 500;
- 600) for detection of formation or production water from drilling fluid comprising:
- enabling (402-408;
- 602) a sampling chamber to receive the drilling fluid from a bypass line of a flow line at a well site;
- performing (410-412;
- 604, 606) spectroscopy of the drilling fluid to generate spectra;
- processing (414-416;
- 502-508;
- 608) the spectra to generate data associated with at least identification formation or production water in the drilling fluid;
- and
- communicating (610) the data to a receiver located externally from the downhole environment.
