Abstract: A formation evaluation system and method. A formation evaluation system includes an assembly interconnected as part of a tubular string and displaceable to multiple positions proximate each of multiple zones intersected by a wellbore. The assembly includes at least one formation evaluation instrument for determining a characteristic of formation fluid, and a pump which draws the fluid into the assembly. A method of evaluating multiple subterranean zones during a single trip into a wellbore includes the steps of: interconnecting a formation evaluation assembly in a coiled tubing string; for each of the multiple zones, displacing the formation evaluation assembly to a position proximate the respective zone, receiving formation fluid from the respective zone into the formation evaluation assembly, and determining at least one characteristic of the formation fluid; and performing the multiple displacing, receiving and determining steps during the single trip of the coiled tubing string into the wellbore.

Abstract: Some aspects of the present disclosure include monitoring fluid flow in a subterranean reservoir. In some implementations, a sealant mixture is injected into a subterranean reservoir to form a flow barrier in the subterranean reservoir. The sealant mixture includes a sealant material and a tracer. The tracer may be stored in the flow barrier, and the tracer may be displaced from the flow barrier, for example, by fluid flow in the subterranean reservoir. The displaced tracer may be detected, for example, in fluid produced into a well bore in the subterranean reservoir. Fluid flow in the subterranean reservoir may be analyzed based on detection of the tracer.

Abstract: A method comprises providing a fluid source in a subterranean formation; providing a wellbore in the subterranean formation; and providing an in-situ barrier, wherein the in-situ barrier is disposed within the subterranean environment and modifies the flow pattern of at least one fluid within the subterranean formation that is provided by the fluid source and flows towards the wellbore.

Abstract: Production of a well is predicted by associating log profiles for wells in a reservoir to production indicators for wells in the reservoir. A log for the well is matched to a corresponding log profile. The log profiles may each be generated by clustering logs for wells in the reservoir. The log profiles and logs may include magnetic resonance imaging (MRI) and/or other suitable data.

Abstract: Methods are provided for detecting the surface and/or subterranean locations of well treating fluids after the treating fluids have been introduced into wells and used for performing treatments therein. The methods of determining the subterranean locations of treating fluids basically comprise introducing a treating fluid into a well having a non-hazardous thermal neutron absorbing material combined therewith and performing a treatment in the well with the fluid. Fast neutrons from a source thereof are emitted in the well after the treatment whereby they interact with elements in the well and are thermalized. The thermal neutrons backscattered in the well are detected, and a count representing the detected thermal neutrons is generated. The subterranean locations of the treating fluid are determined by comparing the thermal neutron counts in the well before and after placement of the thermal neutron absorbing treating fluid therein.

Abstract: A fracturing treatment schedule, including several phases of fracturing fluid quantities and corresponding concentations, is designed within maximum constraints imposed by a job pump time and a critical proppant concentration which are derived in response to a monitored pressure versus time test in the well. Intermediate factors used in quantifying the job pump time and the critical proppant concentration are derived from emiprically created correlations to a particular parameter derived from the pressure versus time graph. The parameter is specifically defined as a pump-in test leak-off factor corresponding to the time in minutes for the monitored pressure to decrease a predetermined amount from the pressure level existing at a predetermined time after the well has been shut-in during the test.
