Abstract: The present invention features a method and system for extraction of oil from drill cuttings. The extraction is carrying out by using a solvent. The extraction conditions preferably include a temperature and pressure each elevated above ambient and optionally to at least the critical point of the solvent. The cleaned drill cuttings may include not more than 1 wt. % oil.

Abstract: The present invention relates to methods and compositions for treating subterranean formations. More particularly, the present invention relates to polymersomes, viscosifying agents that comprise polymersomes, and associated methods of use. In some embodiments, the present invention discloses methods of treating a section of a subterranean formation that comprises the steps of providing a viscosified treatment fluid that comprises an aqueous-based component, and a viscosifying agent that comprises a polymersome; and treating the section of the subterranean formation. In other embodiments, the present invention discloses methods of viscosifying a treatment fluid, suspending particulates in a treatment fluid, fracturing a subterranean formation, providing sand control in a section of a subterranean formation, and encapsulating treatment fluid additives.

Abstract: This invention relates to methods of crosslinking polysaccharides to form crosslinked polysaccharides, and more particularly, to crosslinked polysaccharides that may be incorporated in fluids useful in, for example, applications requiring a crosslinked viscoelastic gel. In one embodiment, the present invention provides a method of crosslinking a polysaccharide comprising the steps of: providing a metal coordinating group having a reactive site, derivatizing a polysaccharide with the metal coordinating group to produce a derivatized polysaccharide having bidentate ligands, and crosslinking the derivatized polysaccharide having bidentate ligands with a metal ion to form a metal ligand coordination complex.

Abstract: The present invention is directed to a method and system for determining parameters inside a subterranean formation. In accordance with the present invention, a plurality of wireless data sensors are injected into the pores or fractures of a subterranean formation. The data sensors includes sensors that record parameters such as temperature, pressure and certain time stamps. Either autonoumously or upon command from a data interrogator tool located down hole, the plurality of data sensors form a wireless ad hoc network and telemeter the recorded data back to the data interrogator tool, which in turn communicates the data to a microprocessor located at the surface. Based on these data, the spatial distribution of the sensors and formation parameters such as temperature and pressure at each data sensor inside the subterranean formation can be obtained.

Abstract: Methods of cementing in well bores using cement compositions having elasticity or high compressive strength and low permeability are provided. The cement compositions basically include particulate acid-degradable glass, water, at least one water-soluble polymerizable alkenoic acid monomer, and a water-soluble free-radical initiator.

Abstract: Plant growth regulating preparations comprising: (a) 0.1-20 wt. % of a 16,17-dihydro gibberellin of formula (Ia) or (Ib); (b) up to 99.9 wt. % of a formulation additive selected from: (b1) the reaction products of triglycerides based on carboxylic acids having 2-30C and ethylene oxide and/or propylene oxide in the presence of a base, and/or (b2) fatty acid alcohol polyethoxylates; (c) up to 50 wt. % of an organic solvent; (d) 0.1-50 wt. % of a formulation auxiliary different from (b1) and (b2); (e) up to 50 wt. % of additional plant growth regulating compounds can be used in agriculture and horticulture to induce the desired effects on, for example, seed germination and seedling growth, rooting, dormancy, juvenility, maturity and senescence, flowering, abscission of leaves, flowers and fruit, fruit set and development, tuber formation, growth of shoot and root, photoassimilation, control of unwanted plants and senescence of whole plants or single organs.

Abstract: Ring D-modified gibberellin compounds are effective in promoting or inducing a desired tissue morphology and/or physiological state in plants, giving effects such as growth retardation or inhibition and inhibition of floral development.
