摘要： A method of drilling with a wellbore fluid, wherein the wellbore fluid forms a filtercake on a wellbore wall, that includes pumping the wellbore fluid with an oxidative degradable polymer and an inactivated oxidant; forming a filtercake in a downhole environment by the pumping of the wellbore fluid into a well and allowing some of the fluid to filter into a subterranean rock formation to produce a filtercake comprising the oxidative degradable polymer and inactivated oxidant; and removing the filtercake formed by the wellbore fluid from the wellbore walls by exposing the filterckae with a breaker fluid comprising an aqueous fluid, and at least one iminodiacetic acid or a salt thereof is disclosed.

摘要： A downhole debris recovery tool including a ported sub coupled to a debris sub, a suction tube disposed in the debris sub, and an annular jet pump sub disposed in the ported sub and fluidly connected to the suction tube is disclosed. A method of removing debris from a wellbore including the steps of lowering a downhole debris removal tool into the wellbore, the downhole debris removal tool having an annular jet pump sub, a mixing tube, a diffuser, and a suction tube, flowing a fluid through a bore of the annular jet pump sub, jetting the fluid from the annular jet pump sub into the mixing tube, displacing an initially static fluid in the mixing tube through the diffuser, thereby creating a vacuum effect in the suction tube to draw a debris-laden fluid into the downhole debris removal tool, and removing the tool downhole debris removal tool from the wellbore after a predetermined time interval is also disclosed. Further, an isolation valve including a housing, an inner tube disposed coaxially with the housing, and a gate, wherein the gate is configured to selectively close an annular space between the housing and the inner tube is disclosed.

摘要： A composition may include a branched polymer to encapsulate a guest molecule to be released under oilfield conditions. The guest molecule may include a production chemical, such as a scale or corrosion inhibitor. The branched polymer may be substituted with fatty acids. The branched polymer may also function as both an ecapsulator as well as a production chemical in certain applications.
