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 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.


A silica-based stationary phase for chromatography columns and the methods of preparing such. More particularly, but not by way of limitation, a silica-based stationary phase that is substantially free of polyethers (e.g., polymer glycols). Also, a chromatography column comprising a silica-based stationary phase substantially free of polyethers (e.g., polymer glycols) within its channels as either a thin-film coating and/or a monolith and/or a monolithic coating. More particularly, a micro-electro-mechanical system (MEMS) chromatograph comprising a silica-based monolith substantially free of polyethers (e.g., polymer glycols) as the stationary phase within the micro-channels of the column.

The disclosure relates to a heat exchanger (100) for heating a drilling fluid, comprising :- an outer body (102) comprising an inner chamber (113) ;- an inner element (104) fitted in the inner chamber;said inner element comprising a helical groove (144), said groove and a wall (112) of the inner chamber defining a path for the fluid ;and- a heating source (106) for heat exchange with said path ;the inner chamber further comprising at least one opening (116), the inner element being able to be removed from the inner chamber through said at least one opening ;the outer body further comprising at least one removable lid (120) closing said at least one opening of the inner chamber.


The disclosure relates to an installation for monitoring a drilling fluid exiting a wellbore, the installation comprising a main pipe for discharging the drilling fluid out of the wellbore, a by-pass pipe having an inlet and an outlet in fluid communication with the main pipe , and a flow monitoring sensor situated in the by-pass pipe. The installation further comprises at least one of a main closing device for opening and/or closing the main pipe and a by-pass closing device for opening and/or closing the bypass pipe, and at least an additional sensor for determining at least a parameter relative to the wellbore and a control device for controlling at least one of the main and by-pass closing devices in function of the parameter.


Systems and methods are provided for estimating and/or using drilling efficiency parameters of a drilling operation. A method for estimating drilling efficiency parameters may include using a borehole assembly that includes a drill bit to drill into a geological formation. A number of measurements of weight-on-bit and torque-on-bit may be obtained during a period in which weight-on-bit and torque-on-bit are non-steady-state. The measurements of weight-on-bit and torque-on-bit may be used to estimate one or more drilling efficiency parameters relating to the drilling of the geological formation during the period.
