A method of monitoring a subterranean operation includes sampling fluid from a borehole during the operation, and estimating, in near real time, a concentration of one or more gases in the sampled fluid and an isotope composition of the sampled fluid. The method also includes identifying an operational inefficiency in the operation based on the isotope composition associated with the one or more gases, and performing, during the operation, at least one of: alerting an operator and adjusting an operational parameter of the operation, based on identifying the operational inefficiency.

Quantifying operational inefficiencies utilizing natural gasses and stable isotopes

Methods, systems, devices, and products for well logging. Methods include conveying a logging tool in the borehole on a carrier; obtaining a borehole image over at least one interval of borehole depth from well logging measurements with a downhole imaging instrument; obtaining acoustic information representative of acoustic reflections from a far-field region of the formation; obtaining quantitative borehole fluid information indicative of properties of a formation fluid in a near-field region of the borehole; generating a borehole connectivity fracture model of the formation in dependence upon the borehole image, the quantitative borehole fluid information, and the acoustic information. Methods may include identifying near-field fractures from the borehole image, and/or identifying far-field fractures from the acoustic information. Methods may include generating a fracture interpretation correlating the near-field fractures with the far-field fractures, and generating the borehole connectivity fracture model of the formation in dependence upon the fracture interpretation.

Estimation of fracture properties based on borehole fluid data, acoustic shear wave imaging and well bore imaging

A method of estimating one or more properties of an earth formation includes acquiring formation fluid data indicative of a qualitative property of a formation fluid in a near-field region of an earth formation surrounding a borehole, the near field region including a surface of the borehole, and acquiring acoustic data based on acoustic signals transmitted into a far-field region of the formation, and estimating a property of one or more fractures in the far-field region based on the acoustic data. The method also includes combining the formation fluid data and the acoustic data, and estimating, by a processing device, at least one fracture characteristic of the formation in the near-field region and the far-field region based on the combined data.

Estimation of fracture properties based on borehole fluid data and acoustic imaging

Methods and systems for generating intervention programs for a downhole formation including collecting mud-logging data during a drilling operation, wherein the drilling operation forms a borehole through the formation, generating zone characterization of one or more zones along the borehole based on the collected mud-logging data, defining targeted zones of the one or more zones along the borehole, generating a treatment characterization for each targeted zone based on the collected mud-logging data, and generating an intervention treatment design based on the targeted zones and associated treatment characterizations.
