A method for improving an inwards stability of an existing levee including a landslide slope (28) and a landside berm (32). The method comprises placing columns (60) through the landside berm into one or more soft soil layers (40) with corresponding soil volumetric weights (s), wherein the columns have a column volumetric weight (c) that is at least 10% larger than the soil volumetric weights, and wherein the columns comprise a mineral aggregate and an impermeable filler.


The disclosure relates to a method for estimating a flow out of at least one fluid pump for injecting fluid in a well, comprising :- determining a calculation model for the flow rate of a pump exiting the at least one pump, said calculation model permitting the calculation of the flow rate in function of at least one calculation parameter (p, SPM) related to the at least one fluid pump ; then- providing at a plurality of measuring times (t_(m)), a set of measurement values (p, p_(B,m), SPM_(DH,m), SPM_(B,m)) representative of said at least one calculation parameter ; then- estimating (86) the flow rate exiting the pump in function of the model and of said at least one calculation parameter.


A gas-extraction device (52) for extracting at least one gas contained in a drilling mud, the device comprising an enclosure (62), an equipment (64) for supplying the drilling mud to the enclosure (62), and an equipment (70) for introducing a carrier gas into the enclosure (62). The device further comprises a flow regulator (104) able to regulate the flow rate of a gas flow containing at least carrier gas, and a pressure controller for locally setting a pressure distinct from the pressure of the enclosure (62). The flow regulator (104) is interposed between the pressure controller and the enclosure (62) and the pressure controller is configured so that the one of the pressure controller and enclosure (62) which is situated upstream from the flow regulator (104) has a higher pressure than the one situated downstream.


The disclosure relates to a method for determining the content of at least one gas compound contained in a drilling fluid having a set of physical properties, the method comprising:- extracting out of a sample of the drilling fluid a gas fraction of the or each gas compound;- measuring a representative information (y(i)) of the or each gas fraction of each gas compound;- obtaining, for the or each gas compound a correcting factor () relating the measured informatlon (y(i)) for the gas fraction of each compound to the content of said compound in the drilling fluid;wherein the estimated correcting factor () used for the or each gas compound is obtained on the basis of a set of previous correcting factors (p_(0)(i)), previously obtained from calibration of reference drilling fluids, each of the reference drilling fluids having at least one physical property substantially identical to the corresponding physical property of the extracted drilling fluid.


The present disclosure concerns a method for detecting gain or loss of drilling fluid in a drilling installation, said drilling installation comprising a drilling pipe, drilling fluid pits and a hydraulic connection between the pits and the drilling pipe. Said method comprises:- providing (116, 118), during a first period, a set of measurement values (va_(i,m) ; vc_(j,m)) representative of a volume of drilling fluid in each of the pits belonging to a predetermined group (112, 113) ; then- based on volume measurement values, identifying (148) volume variations occurring during the first period for the pits of the predetermined group, each volume variation of a pit being associated with a volume variation period ;- calculating (162), for each measuring time (t_(m)), a corrected cumulated volume of drilling fluid (V_(m)) for the pits of the predetermined group, based on the identified volume variation occurring in at least a sub-group (113) of the predetermined group, and- estimating (163) a first value (A_(m)) for a gain or loss of drilling fluid at a measuring time (t_(m)) by comparing the corrected cumulated volume (V_(m)) with an expected value (V_(0)).


The present disclosure concerns a method for detecting gain or loss of drilling fluid in a drilling installation, said drilling installation comprising a drilling pipe, drilling fluid pits and a hydraulic connection between the pits and the drilling pipe. Said method comprises:


Method of determining the content of at least one drilling compound in a drilling mud, comprising:- obtaining a first flow of said drilling mud exiting a wellbore,- performing a first gas extraction by injecting at least a first part of the first flow in a first extraction device (53A) and extracting gas from the first extraction device in order to obtain a first extracted gas and a second flow of drilling mud, and measuring at least a first parameter representative of a gas fraction of said drilling compound in the first extracted gas, and- using at least the first parameter and a correction factor in order to calculate said content;- performing a second gas extraction in a second extraction device (53B) distinct from the first extraction device in order to obtain at least a second extracted gas and a third flow of drilling mud, and measuring at least a second parameter representative of a composition of the second extracted gas, and- using at least the second parameter in order to calculate the correction factor.

Geoservices | Date: 2016-08-24

The disclosure is related to a device for extracting at least one gas contained in a drilling fluid, comprising:- an extraction enclosure;- a recovery vessel downstream of the enclosure, connected to a suction apparatus downstream of the recovery vessel- a gas-extraction pipe having an inlet opening in the extraction enclosure and an outlet opening in the recovery vessel- a maintenance pipe having an inlet connected to the vessel, an outlet in fluid communication with the outside of the vessel and a siphon-forming section. The device is configured so that the dimension along a vertical axis between the highest location of the gas-extraction pipe and the inlet is greater than the dimension along the vertical axis between the outlet of the maintenance pipe and the lowest location of the maintenance pipe.


The disclosure relates to a method for processing data collected during a mud logging analysis, comprising:- providing, at a plurality of measuring times, a set of gas measurement values representative of the quantity of at least one gas contained in several samples of a drilling fluid,- providing, at a plurality of controlling times, a set of control values of a control parameter relative to part of an analysis unit for providing the gas samples or the gas measurement values;- matching, for each sample of the drilling fluid, the gas measurement value measured at a given measuring time with at least one control value measured at a controlling time;- evaluating whether each control value of the control parameter is in a normal state.
