An installation () for drilling a well () into a soil comprising: &#x2014;a discharge pipe () connected to the well () for recovering a drilling mud created by the drilling fluid mixing with components from the soil; &#x2014;a flow rate sensor () to measure at least one parameter of the recovered drilling mud and generate a parameter value; &#x2014;a calculator () connected to the flow rate sensor () to receive the parameter value in order to calculate a flow rate of the recovered drilling mud using the parameter value; characterized in that it further comprises a flume () having a throat and an approach channel hydraulically connected to the discharge pipe () to receive the recovered drilling mud, the measured parameter of the recovered drilling mud being representative of a height of the recovered drilling mud in the approach channel.

Installation for drilling a well into a soil and associated drilling method

A method is presented for determining at least one piece of information representative of a phase fraction of a fluid in a pipe. The method comprises the estimation of a number of counts received in each measuring interval based on each piece of representative information determined at a preceding iteration, then calculating a residual comprising a first criterion calculated from probabilities using a given statistical law to measure, for each energy, the number of counts measured in each interval, the given statistical law being parameterized based on the number of estimated counts.
