| titleOfInvention | Downhole optical chemical compound monitoring device, bottom hole assembly and measurements-while-drilling tool comprising the same, and method of optically monitoring chemical compound downhole during drilling |
| abstract | A downhole optical chemical compound monitoring device ( 30 ) arranged to be integrated in a mandrel ( 20 ) of a drilling system, for monitoring a chemical compound in a drilling fluid ( 14 B) circulated through a well ( 7, 8 ), the downhole optical chemical compound monitoring device ( 30 ) comprising: n an analysis cell part ( 31 ) comprising an open cavity ( 40, 140 ) into which the drilling fluid ( 14 B) is free to flow; n a first optical probe ( 41 A, 141 A) coupled to a light source ( 157 ) and arranged to transmit a light energy into the open cavity ( 40, 140 ); n a second optical probe ( 41 B, 141 B) coupled to a detector ( 158 ) and arranged to produce in use a signal resulting from an interaction of the drilling fluid ( 14 B) present in the open cavity ( 40, 140 ) with said light energy, indicative of a quantity of chemical compound present in the drilling fluid ( 14 B); n each of said optical probes is mounted through a wall ( 38 A, 38 B, 138 A, 138 B) of the analysis cell part ( 31 ) in a sealed manner and has a tip ( 45 A, 45 B), the tip being needle shaped and having an external diameter less than 1 mm; and n the first optical probe ( 41 A, 141 A) and the second optical probe ( 41 B, 141 B) are arranged such that the first and second tips of the respective optical probes project into the open cavity ( 40, 140 ) and such that the first tip ( 45 A) of the first optical probe ( 41 A, 141 A) faces the second tip ( 45 B) of the second optical probe ( 41 B, 141 B) at a defined distance ranging from 10 μm to 10 mm. |
