| titleOfInvention | Downhole optical chemical compound monitoring device, bottom hole assembly and measurement-while-drilling tool comprising the same |
| abstract | A downhole optical monitoring device 30 for integration into a drilling system mandrel 20 for monitoring chemical compounds in drilling fluid in a well comprises: an analysis cell 31 comprising open cavity 40 into which the drilling fluid is free to flow; a first optical probe coupled to a light source and arranged to transmit light energy into the open cavity, in emitter part 32; a second optical probe coupled to a detector arranged to receive a signal resulting from interaction of the drilling fluid in the open cavity with said light energy, in detector part 30, indicative of a quantity of chemical compound present in the drilling fluid; each optical probe is mounted through a wall of the analysis cell 31 and has a needle shaped tip having an external diameter less than 1 mm; and the first and second probes are arranged such that the first and second tips of the respective probes project into the open cavity 40 such that the first tip faces the second tip at a distance from 10μm to 10mm. A spectrum of the fluid may be obtained. |
