A method is detailed for obtaining data useful in the analysis of fluid communication and migration between first and second horizons intersected by a wellbore. In the practice of this method, a pressure transducer is fixedly attached to a length of casing. The casing is inserted into the well such that the transducer is positioned proximate the first horizon. The annulus between the face of the wellbore and the casing is then filled with cement and the cement is permitted to cure. The output of the transducer is monitored and recorded. A change in the pressure observed at the first horizon corresponding to a known change in the pressure at the second horizon is indicative of fluid communication between the two horizons. The change in the pressure condition of the second interval can be induced artificially by the injection of fluids into the second interval or by the production of pore fluids from the second interval.

Plugging perforations in casing in a wellbore penetrating a subterranean formation using degradale ball sealers. The ball sealer used is composed of a polyester polymer which is substantially insoluble in the wellbore fluid. The polymer degrades in the presence of water at an elevated temperature to form small molecules which are soluble in a fluid in the subterranean formation. After the polymer degrades, the flow through the perforation returns to substantially its initial value.

The present invention relates generally to the composition and method for reducing the permeability of subterranean formations penetrated by a wellbore. The composition of the present invention comprises a wellbore fluid having dispersed therein a fluid loss control agent comprising a polyester polymer which is substantially insoluble in the wellbore fluid. The polymer degrades in the presence of water at an elevated temperature to form small molecules which are soluble in a fluid in the subterranean formation. The method of the present invention comprises reducing the permeability of subterranean formations penetrated by a wellbore by placing the composition of the present invention down the wellbore.

A Method of coating particulate materials (such as silica sand, glass beads, seeds and metal particles) with a liquid thermosetting epoxy resin which comprises agitating the epoxy resin with the particles in a nonpolar liquid, which is immiscible with the epoxy resin, and contains a nonionic surfactant having a molecular weight of at least 2,000 to retard the tendency of the epoxy coated particles to agglomerate during curing of the resin in the non-polar liquid. A suitable liquid for use as the immiscible liquid is a paraffinic oil which is aromatic-free and olefin-free.

A method for sequential treatment of formation strats when treating fluid is pumped into a well at a matrix rate by temporarily closing perforations in the well casing. The perforations are closed by ball sealers injected into the wall during the treatment. The ball sealers are sized to plug the perforations and have a density less than the density of the treating fluid. The treating fluid is injected at a rate which transports the ball sealers to the perforations but which is sufficiently low to prevent formation fracture.

In a method of treating a subterranean formation, a well treatment composition comprising a dispersion of a water-in-oil emulsion in an aqueous medium is injected into the formation. The water-in-oil emulsion has an internal aqueous phase and an external phase containing a liquid hydrocarbon and a surfactant soluble in the hydrocarbon. The compositions can be designed to perform various well treatment applications including hydraulic fracturing and acidizing and can also be used to encapsulate or to transport well treatment materials and chemicals into the wellbore or formation. Treatment methods may also employ dispersions of a reactive simple or multiple emulsion. The distinct phases of the compositions may be selected to form treatment solutions upon mixing. Thus, improved acidizing may be achieved through an in situ reaction format.

Apparatus and method for detecting flow outside Casing in a well are provided. The flow may be detected by logging tools or by fixed equipment inside casing. An alarm system is provided for lack of mechanical integrity of a wellbore. Stationary temperature sensors are placed in contact with the inside wall of the casing. Electronic circuits are used to provide output signals sensitive to differences in temperature of the sensors.
