Abstract: Methods of treating a subterranean formation penetrated by a well bore, by diverting treatment fluid stages from zones of higher permeability to zones of lower permeability with an acid precursor material and fibers. The acid precursor material has an average particle size less than 1000 microns.

Abstract: A technique facilitates monitoring of events related to various well operations. According to an embodiment, the technique provides a non-invasive approach to measuring fluid and solids transport through well surface pipe assemblies. The desired information may be detected and obtained by mounting sensors to the exterior of pipes, thus enabling retrofitting of the sensor system to existing assemblies at a desired time during a given operation. Additionally, the technique may utilize a combination of sensors and systems for measuring fluid and solids transport through well flow path assemblies. The measurements obtained may be used to provide real-time monitoring of surface flow conditions as well as of downhole wellbore conditions and of the status of downhole equipment.

Abstract: Methods disclosed for reducing the loss of a circulating fluid in a wellbore to an adjacent subterranean formation during a wellbore operation include coiled tubing milling, cleanout and gravel-packing operations. The methods include placing, either before, during, or before and during the operation, a first acid precursor material, and optionally fibers, in contact with the subterranean formation adjacent to the wellbore to at least partially form a temporary reservoir barrier and reduce hydraulic conductivity between the wellbore and the subterranean formation. The first acid precursor material has a first average particle size of about 3000 microns or less.

Abstract: Methods of treating formation damage or other service induced damage in a near wellbore region of a wellbore of a subterranean formation, by treating a zone or zones in the near wellbore region, and diverting treatment fluid stages from the treated zones to untreated zone(s) with an acid precursor material and optionally also with fibers. The acid precursor material has an average particle size less than 1000 microns.
