Processes for adding a chemical composition to a produced water mixture upstream of a pad related to a well to be fracked are described. The added chemical composition comprises a drag reducing agent, or a biocide, or a scale inhibitor, or any combination thereof. The produced water mixture comprising the added chemical composition may then be transferred in a pipeline to the well to be fracked.

Processes for chemical dosing prior to the pad

A method for evaluating a chemical treatment at a subsurface for improved well performance may include obtaining information about a post-reaction fluid that results from a fluid flowing through a testing vessel for a period of time, where the testing vessel comprises a plurality of materials, where the plurality of materials is designed to be representative of the subsurface, and where the plurality of materials comprises rock and proppant. The method may also include performing, using the information, a compatibility test on the post-reaction fluid and the plurality of materials after the period of time. The method may further include evaluating, after performing the compatibility test, an effect of the post-reaction fluid on the plurality of materials.

Optimizing chemical treatment at the subsurface for improved well performance

A missile for a hydraulic fracturing system can include a high-pressure (HP) manifold, a low-pressure (LP) manifold, and a main manifold in between. The missile is configured to simultaneously fracture three or more wells. The HP manifold has multiple input channels, an output channel, and a main channel disposed in between. The LP manifold includes a LP input channel, multiple LP output channels, and a LP manifold in between.

Systems and methods for simultaneously fracturing multiple wells from a common wellpad

The present disclosure provides methods and systems for hydrofracturing processes utilizing native drilling cuttings to enhance wellbore permeability. The native drilling cuttings are obtained during drilling operations and may be used in hydrofracturing applications without further grinding or processing. The native drilling cuttings can be combined into a slurry and injected into a well for the hydrofracturing application. In some cases, the native drilling cuttings are dried before combining them with the slurry.

Hydrofracturing applications utilizing drilling cuttings for enhancement of wellbore permeability

A system for fracturing multiple wellbores on a multi-well pad can include a missile that receives high-pressure fracturing fluid from a plurality of pump truck. The system can also include a main manifold that receives the high-pressure fracturing fluid from the missile, where the main manifold includes multiple valves and multiple output channels, where each of the valves are operated between an open position and a closed position. The system can further include multiple wellbores including a first wellbore, a second wellbore, and a third wellbore, where the wellbores are connected to the output channels of the main manifold. The valves of the main manifold can be operated to enable simultaneous flow of the high-pressure fracturing fluid to the first wellbore, the second wellbore, and the third wellbore so that the first wellbore, the second wellbore, and the third wellbore are fractured simultaneously.
