摘要： Methods and compositions are disclosed for controlled addition of components that decrease the viscosity of the viscoelastic surfactant fluids or for controlled changes in the electrolyte concentration or composition of the viscoelastic surfactant fluids. One aspect of the invention relates to the use of internal breakers with a delayed activation. Another aspect of the invention relates to the use of precursors that release a breaking system such as alcohol by a process such as melting, slow dissolution, reaction with a compound present in the fluid or added to the fluid during or after the step of injecting, rupture of an encapsulating coating and de-adsorption of a breaking agent absorbed into solid particles. In another aspect of the invention, alcohols are included in a pad to reduce the low-shear viscosity and reduce the resistance to flow of the treatment fluids during a desired phase of the treatment.

摘要： A method is provided for diverting the majority of the fluid injected into a stratified subterranean formation, that has at least one problematic zone and at least one hydrocarbon zone, into the hydrocarbon zone. In the method, a viscous diverting fluid made with a gelling amount of a surfactant and an acid is injected before the main treatment; after the treatment the acid decomposes the surfactant. The main treatment may be hydraulic fracturing, acid fracturing and matrix acidizing. The fluid used as the diverting fluid may also be used as the carrier fluid in hydraulic fracturing or gravel packing. Destruction of the surfactant alleviates the potential of diverters or carrier fluids to damage formations.

摘要： A computer controlled heave compensation wireline logging winch system and method of use that compensates for the effects of wave motion on floating installations performing wireline logging measurements. A wireline winch and wireline cable with a logging measurement tool attached is installed on a floating installation. Vessel vertical movement is measured and is physically compensated for by a change in speed of the wireline cable so that the logging data is obtained at a controlled speed. Any error in this physical compensation is detected by a depth measurement system and is used to adjust the true depth at which the logging tool measurements are being recorded.

摘要： The invention provides a method of isolating an open hole fitted with a slotted liner, the method consisting in pumping a cement or a resin to the level of the slotted liner by means of injection apparatus provided with lips for scrapping the slotted liner downstream from the injection point so that the cement or resin fills the entire borehole upstream from the injection apparatus and also fills the space behind the slotted liner while the apparatus is being raised towards the surface. The invention also provides injection apparatus particularly adapted to implement the method, which apparatus can advantageously be displaced by means of coiled tubing.

摘要： The invention relates to a method of obtaining a developed two-dimensional image of the wall of a borehole. The method comprises the steps consisting in:

measuring (1) a primary physical magnitude in said borehole as a function both of depth and of azimuth;
measuring (2) a secondary physical magnitude in said borehole as a function of depth;
establishing (13) a relationship ( f ) between said primary physical magnitude and said secondary physical magnitude; and
deducing (14) from said relationship values for said secondary physical magnitude as a function both of depth and of azimuth, which method makes it possible to reconstruct a two-dimensional image developed over the wall of a borehole concerning a secondary physical magnitude which is measured in said borehole as a function of depth only. The invention is particularly applicable to density imaging.

摘要： The present invention relates to a method of modelling a circuit travelled by a drilling mud during drilling, the circuit including both the well and the surface equipment, in particular solid separation devices, in which method, for each time sequence, there are calculated the mass concentration of each liquid and solid species present in the mud, the total flow rate, and the grain size distribution of each solid species downstream from each item of equipment. The invention also provides inversion of the above method to estimate the size of the cuttings on the basis of the measured efficiency of solid separation devices.

摘要： An NMR measurement apparatus is potentially subject to relative motion between the apparatus and a sample. The measurement apparatus includes at least one magnet, at least one coil and circuitry that is coupled to the magnet(s) and coil(s). The circuitry is adapted to use the magnet(s) and coil(s) to perform at least one NMR measurement and indicate the results of the NMR measurement(s). The results are then analyzed to determine an effect of the motion on the measurement(s).

摘要： The present invention concerns a fluid loss control agent for a petroleum industry (or analogous) cement slurry, comprising a surfactant and a micro-gel obtained by chemical cross-linking of a polyvinyl alcohol. The micro-gel and the surfactant are advantageously compatible with a wide range of petroleum industry cement additives and can also produce compositions which are gas tight.
