摘要： A method and composition for distinguishing native hydrocarbons in a formation from oil-based drilling fluid with nuclear magnetic resonance (NMR) is provided so that NMR may be used in analyzing formation fluids from boreholes drilled with oil-based drilling fluids. In the method, the drilling fluid is doped with oil solubilized paramagnetic species before or during drilling of the borehole. The paramagnetic species cause a shift in the T1 and T2 NMR response of the drilling fluid.

摘要： Metal cross-linked phosphate ester compositions impart fragile progressive gel structure to a variety of oil and invert emulsion-based drilling fluids at neutral or acidic pH. The fluids are useful for drilling wellbores in subterranean formations without need for organophilic clays to suspend drill solids. At greater concentrations, metal cross-linked phosphate ester compositions enhance fluid viscosity for suspending weighting materials in drilling fluids during transport of the fluids, as from a manufacturing or mixing facility to a drilling site.

摘要： An improved acidization solution is provided which comprises water and one or more esters or polyesters of hydroxy acid or of glycerol. The solution may include, for example, ethyl lactate and pure water or a brine. The hydrolysis of the esters or polyesters occurs at a slower reaction rate than that of several other known acidization esters, such as diethyleneglycol diformate, at temperatures higher than 60° C. or even higher than 100° C. Thus, the acidization solution may be distributed substantially throughout a region in a well where acidization is required before hydrolysis is completed, despite being exposed to relatively high temperatures. The hydrolysis may result in the slow release of an acid that is capable of consuming all or most of an undesirable substance in the well, e.g., a filter cake.
