- Most drilling fluids contain reducing filtrate additives which prevent filtration of the drilling fluid in the permeable formation by creating a cake (deposit on the walls of a layer of colloidal particles) whose quality of impermeability conditions the amount of fluid filtered.
- the drill rods in rotation stop can stick on the walls, against or in the cake.
- the nature of the loosening fluid must be adapted to the method of placing by circulation, that is to say being of a density equivalent to the fluid already in place, of a viscosity such as injection and circulation in the well is not a problem, and comply with the quality standards for rejection in force.

- the differential pressure test cell known as "Differential Sticking Tester - Model 21150" from Baroid, a division of NL Corp. (Instruction Manual Part N °. 211150001EA) has been modified in such a way that, once the cake is formed on the filter and the piston applied in contact with the cake, replace the mud used to form the cake with another fluid, for example a loosening fluid according to the invention, or comparison fluids.
- a test cell consists of a cylindrical chamber comprising a paper filter holder, a lower outlet for collecting the filtrate, an upper cover comprising a pressurization orifice with compressed nitrogen and a shaft carrying a disc disposed in the axis of the filter paper, a torque wrench linked to the shaft to measure the resistant torque caused by the disc in contact with the cake.
- the contact face of the disc has been slightly modified to present a flat bordered by a very flat trunk of cone, of width not exceeding the centimeter.
- the operational conditions are as follows: ambient temperature for the fluids, differential filtration pressure 3.5 MPa, pressure of the disc on the cake equivalent to 5 MPa, for 10 minutes.
- a characteristic test is therefore carried out as follows: The mud is filtered on a paper filter for 30 minutes under a pressure of 3.5 MPa, then the piston is pressed into the cake under an equivalent mechanical pressure of 5 MPa, for 10 minutes . The differential pressure is then canceled, the piston still being kept applied to the cake under the action of mechanical force. The sludge remaining in the cell is then removed and replaced by the loosening fluid to be tested. The differential pressure of 3.5 MPa is then applied again and the mechanical force exerted on the piston is eliminated. After 30 minutes, we measure the torque necessary to lift the piston from the cake. The results are expressed in Ibs.in (pound.inch) according to the usual units of the profession (we multiply by 0.11298 to convert to Newton. Meter).
- composition of the basic mud used to make the cake • fresh water
- the results are reported in the table below:
- the first line corresponds to the measurement of the torque when the cell contains the mud, without replacement by the loosening fluid.
- a cake is formed by filtration of a mud in an API filtration cell on filter paper for 30 minutes at 7 bar of pressure and at room temperature.
- the sludge remaining in the cell is then removed, which is replaced either by water (or the filtrate) or by a loosening fluid according to the invention.
- the pressure is then restored and the filtration is measured for 30 minutes. The results are expressed by the weight of fluid recovered after 30 minutes of filtration of the water or the loosening fluid.
- Viscosities the table below gives the viscosity values of the basic components, as well as their mixtures. The viscosities are measured at 40 ° C. The proportion of the two components of L1 must be adjusted so that the mixture has a viscosity of less than 40 mPa.s at a temperature of 40 ° C and preferably less than 20 mPa.s.
- a good ratio corresponds appreciably to the 2-ethylhexyl oleate / COMP mixture of 70/30.
- VA is the apparent viscosity in centipoise (cP)
- VP is the plastic viscosity in centipoise (cP)
- YV the shear threshold value (Yield Value) in lb / 100ft 2 (these measurements comply with API RP 13B-1 which gives the correspondence of SI units in Appendix I).
- the tests consist in measuring the rheology of the formulation as a function of the percentage of Truvis viscosifier added here, and of comparing the decantation of the solids as a function of time.
- Truvis is a viscosifying additive for organic media marketed by Dowell (Schlumberger Dowell Drilling Fluids). It will not depart from the scope of this invention to use other viscosifying products, for example other organophilic bentonites or oleophilic polymers.
- the formulation according to the invention can withstand high concentrations of barite.
- the example below shows that a density of 1.8 kg / 1 can be obtained.
- the loosening fluid formulation tested corresponds to L1 + 1.7% of Truvis viscosifier.
