Abstract: Barite (barium sulfate) scale may be problematic in subterranean formations, wellbores, pipelines, and other locations and may be difficult to remove in many instances. Aqueous fluid compositions effective for removing barite scale may comprise a concentrated mineral acid, a first salt comprising an iodide anion, and a second salt comprising an anion that forms an aqueous-soluble barium salt. One suitable aqueous fluid composition may comprise concentrated hydroiodic acid, an alkali metal iodide, and an alkali metal hypophosphite salt. The aqueous fluid compositions may be used in combination with a second treatment phase comprising a fluid composition comprising at least one acid gas capturing agent. The at least one acid gas capturing agent may comprise a first component reactive toward hydrogen sulfide and an optional second component reactive toward carbon dioxide.

Abstract: A method of performing a remediation process on a flowline comprises: calculating an asphaltene deposition profile characterizing blockage of the flowline by a deposit of asphaltene; determining, based on the asphaltene deposition profile, whether the blockage exceeds a predetermined level of blockage; and treating the flowline with an asphaltene solvent to dissolve at least a portion of the deposit when the blockage exceeds the predetermined level. A computer program product comprises instructions that are stored on a computer-readable medium and that, when executed by a processor, cause an apparatus to: calculate an asphaltene deposition profile characterizing blockage of a flowline by a deposit of asphaltene; determine, based on the asphaltene deposition profile, whether the blockage exceeds a predetermined level of blockage; and determine to treat the flowline with an asphaltene solvent to dissolve at least a portion of the deposit when the blockage exceeds the predetermined level.

Abstract: A method for evaluating and optimizing scale management at a subsurface for improved well performance may include performing multiple first tests, where each first test combines a first fluid with a second fluid, wherein the first fluid comprises a concentration of a scale inhibitor and a chemistry of additional fluid components. The method may also include identifying an optimal mixture of the first fluid among the first tests, where the optimal mixture comprises a minimum concentration of the scale inhibitor that reduces scale deposition. The method may further include performing a second test that combines the first fluid with the scale inhibitor, the second fluid, and rock. The method may also include evaluating a concentration of the scale inhibitor in aqueous phase after a period of time after initiating the second test. The method may further include identifying a target fluid for use in a field operation at the subsurface.

Abstract: A resource exploration and recovery system including a first system, and a second system extending into a wellbore. The second system includes a completion having a casing defining a wellbore internal diameter. Chemical injection tubing extends from the first system into the completion. The chemical injection tubing includes a terminal end portion. A chemical introduction system is arranged at the first system and fluidically connected to the chemical injection tubing. The chemical introduction system is operable to deliver a chemical into the chemical injection tubing. A chemical injection assembly is mounted to the terminal end portion. The chemical injection system includes an anchor system operable to secure the chemical injection assembly to the casing.
