摘要： Various methods and well systems are provided for characterizing a hydraulically-fractured hydrocarbon-bearing formation that is traversed by a well partitioned into a number of intervals. The methods and well systems analyze surface flow characteristics of fluid that flows from the well (for example, using a multiphase flow meter) in order to characterize local formation properties for one or more intervals for one or more intervals (or other sections) of the well.

摘要： In-line electrolysis of well treatment fluid in a method and system to supply a treatment fluid downhole in the well. In the method, a treatment fluid is electrolyzed in a flow path to a downhole location to form one or more electrolysis products. In the system, an electrolysis cell has at least one electrode integrated in the flow path. Also disclosed is a method to treat a subterranean formation by modulating amperage to an electrolysis cell in the flow path to form a heterogeneous concentration of one or more electrolysis products to transform a self-agglomerating solid composition in the fracture into a channelized solids pack comprising clusters having a high concentration of solids, wherein the clusters are separated by open voids having a substantially reduced concentration of solids between the clusters.

摘要： A downhole tool system may include one or more containers to hold waste product and a tractor to convey the one or more containers to a storage location within a wellbore. The downhole tool system may also include an anchor to seal against the wellbore and secure the containers at the storage location. Additionally, the downhole tool system may include a disconnect tool to separate the tractor from the containers such that the tractor may be removed from the wellbore while leaving the containers at the storage location.

摘要： Methods of delivering reactive components to a geological formation disclosed herein include generating a plurality of microholes along a wellbore, the plurality of microholes comprising one or more openings, and the plurality of microholes are configured to connect the wellbore to the geological formation. Methods further include delivering the one or more reactive components to the plurality of microholes via a carrier fluid, wherein the one or more reactive components are configured to enable one or more chemical reactions to occur, and wherein the carrier fluid is configured to expand, and controlling a flow rate of the one or more reactive components based on whether a volume of the one or more reactive components delivered to the plurality of microholes is greater than a threshold volume.

摘要： The disclosure pertains to methods for completing a well may comprise lowering a coiled-tubing in the well thus forming an annulus between the casing and the coiled-tubing, pumping down said annulus a treatment fluid above the fracturing pressure of the formation while also pumping fluid through the coiled tubing. The methods may also comprise monitoring in real-time the bottom hole pressure and increasing the pump rate through the coiled-tubing if an increase of bottom hole pressure is observed.

摘要： A method and system is provided that analyzes flow characteristics of return fluid that flows to a surface-located facility during well operations (such as plug mill-out or cleanout/workover operations) in order to characterize local formation properties of the formation. The method and system can be used to characterize a hydraulically-fractured hydrocarbon-bearing formation that is traversed by a well having a number of intervals that are hydraulically isolated from one another by corresponding plugs.

摘要： Methods for initiating chemical reactions in a wellbore include delivering one or more reactive components via a carrier fluid to the wellbore. The one or more reactive components delivered to the wellbore are configured to enable one or more chemical reactions to occur. The one or more chemical reactions are carried out until a threshold volume of the one or more reactive components is delivered to the wellbore.
