摘要： A dual injection system for selectively injecting a treating fluid in a predetermined treating zone (16) of a well bore hole (10) adjacent a productive zone (14) with a marker fluid injected from the annulus (36) outside a coiled tubing string (34). The coiled tubing string (34) is inserted within the well bore hole (10) and a sensor (40) is provided on the coiled tubing string (34) with a lower end portion (42) extending below the sensor (40) for the discharge of the treating fluid from the lower end (44) of the extending end portion (42). The sensor (40) senses a detectable material, such as a radioactive material, in the marker fluid injected from the annulus (36) outside the coiled tubing string (34) and may be reciprocated within the well with the coiled tubing string (34) for determining the interface (46) between the marker fluid and the treating fluid so that the treating fluid does not enter the productive zone (18). In one embodiment (Figure 4) the productive zone (14A) is located below the treating zone (16A) and the treating fluid contains the marker to provide the marker fluid.

摘要： A well logging fluid is provided having a relatively non-conductive fluid and an effective amount of an electrically conductive fiber sufficient to modify the electrical characteristics the relatively non-conductive fluid resulting in a modified fluid or well logging fluid such that an electrical well-logging tool when disposed in the modified fluid can perform an electrical well-logging survey of a borehole containing the modified fluid. The non-conductive fluid is selected from the group consisting of a non-aqueous fluid and an invert emulsion of an aqueous phase in a non-conductive liquid. In an invert emulsion, the aqueous portion thereof ranges up to about 70 percent by volume. Preferably, the modified fluid or well logging fluid has an electrical stability of at most 350 volts, more preferably at most 250 volts, as measured according to API RB 13-2. The well logging may be used for electric well logging and imaging.

摘要： A method of maintaining the integrity of a sheath, in particular a cementing sheath in a well consists in calculating or estimating variations in well pressure and/or in well temperature and/or in the variations in in-situ stresses, which may occur during the lifetime of the well, evaluating the stresses in the sheath as a function of the above variations, determining the nature of the stress likely to be first in causing deterioration of the sheath, and the risk thereof, and evaluating the influence of the elastic properties of the sheath, of the rock and/or of the casing on this stress, in order to select a sheath which is capable of attenuating this deterioration. The method is of particular application to oil, water, gas, and geothermal wells.

摘要： A method of cementing a well permitting a reduction in the degree of diameter reduction of casing or liners required, and not requiring excessively large initial conductor casing, is described. The method is characterized by provision of an enlarged wellbore and a novel liner structure which is adapted for expansion of a reduced diameter section thereof downhole, providing, before expansion of the section, unimpeded flow of fluid from the enlarged wellbore during cementing and close fit of the expanded section with the casing or preceding liner, after cementing is completed and expansion of the section. A novel well liner structure and novel well liner expansion means are disclosed.
