Abstract: This disclosure describes a method of assessing fractures in an underground formation using temperature profile measured by a DTS. The fractures can be identified by a temperature profile established by the feedback signals obtained from the DTS, but the DTS measurements are made at least 36 hours after a stage is fractured and during shut-in, thus allow crossflow and other noise sources to abate. Further, the size of the temperature differential is indicative of fracture spacing or density, not volume of fluid flow as thought in the prior art. Thus, these methods can be used to optimize the next stage or next well in a fracturing program.

Abstract: A method of optimizing production of a hydrocarbon-containing reservoir by measuring low-frequency Distributed Acoustic Sensing (LFDAS) data in the well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow and simultaneously measuring Distributed Temperature Sensing (DTS) data from the well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow. An initial model of reservoir flow is provided using the LFDAS and DTS data; the LFDAS and DTS data inverted using Markov chain Monte Carlo method to provide an optimized reservoir model, and that optimized profile utilized to manage hydrocarbon production from the well and other asset wells.

Abstract: A system for measuring fluid flow in a wellbore is provided. A probe includes at least a heater. A fiber optic cable is connected to the probe. The system is programmed to perform operations including: changing an output of the heater to thereby change a temperature of drilling fluid moving over a fiber optic cable; measuring a strain on the fiber optic cable caused by changing the temperature of the drilling fluid; preliminarily determining a velocity of the drilling fluid from the measured strain; measuring at least a second parameter of the drilling fluid; adjusting the preliminary determined velocity based on the measured at least a second parameter to yield an adjusted velocity; and determining a flow rate of the drilling fluid based on the adjusted velocity.

Abstract: A matrix production logging tool for measuring the temperature of produced fluids in a wellbore is described. Accurate production allocation to the pathways between the oil/gas well and the reservoir provides required data for the economic optimization of the techniques and procedures used to complete future wells and optimize the existing well. The low maintenance tool provides precise uphole, downhole and inflow temperature measurements of produced fluids within the wellbore. These are obtained at a plurality of locations along the oil/gas well as the tool is withdrawn, thus providing a matrix of temperature measures along the length of the well. From the temperature traces, inflow as well as up and downhole temperature, can be determined, and mass contribution at each inlet determined. With this method, a production profile along the entire well can be determined as used in further well optimization efforts.

Abstract: This disclosure describes a method of calculating fluid distribution from a hydraulically fractured well, especially during a plug-and-perf hydraulic fracturing operation. The Distributed Acoustic Sensing (DAS) data is used to quantify the fluid distribution in separate perf clusters during fracturing, and the result can be used for completion design and optimization, hydraulic fracturing, and ultimately for oil and gas production.
