Systems and methods presented herein include sidewall coring tools used to return core samples of rock from a sidewall of a wellbore as part of a data collection exercise for exploration and production of hydrocarbons. In particular, the systems and methods presented herein perform sidewall coring of a subterranean formation using a combination of rotary and percussive coring. More specifically, the systems and methods presented herein rotate a coring cylinder of a sidewall coring tool back and forth less than a full rotation while pushing the coring cylinder of the sidewall coring tool against a bore wall of a wellbore, and push the coring cylinder of the sidewall coring tool into the subterranean formation to enable extraction of a core sample of the subterranean formation.

Systems and methods for recovering and protecting sidewall core samples in unconsolidated formations

A method includes receiving first fluid property data from a first location in a hydrocarbon reservoir and receiving second fluid property data from a second location in the hydrocarbon reservoir. The method includes performing a plurality of realizations of models of the hydrocarbon reservoir according to a respective plurality of one or more plausible dynamic processes to generate one or more respective modeled fluid properties. The method includes selecting the one or more plausible dynamic processes based at least in part on a relationship between the first fluid property data, the second fluid property data, and the modeled fluid properties obtained from the realizations to identify potential disequilibrium in the hydrocarbon reservoir.

Reservoir fluid geodynamic system and method for reservoir characterization and modeling

A method for determining a dip of a geological structure in a subterranean formation, involves generating, using a 3D resistivity analyzer, a first intermediate result describing the dip of the geological structure based on 3D resistivity data collected from a borehole penetrating the subterranean formation. The method further involves generating, using a borehole image analyzer, a second intermediate result describing the dip of the geological structure based on a borehole image collected from the borehole. The method further involves generating, by a computer processor combining the first intermediate result and the second intermediate result based on a pre-determined criterion, an integrated result describing the dip of the geological structure.

Integrated dip from 3D resistivity tool and borehole imaging tool

A method can include providing borehole data organized with respect to a cylindrical surface, defining one or more bedding planes based at least in part on the borehole data, and transforming at least a portion of the borehole data to a planar slab format for a plane interior to the cylindrical surface. Various other apparatuses, systems, methods, etc., are also disclosed.

Slabbed core format for borehole image data

Computer-based method and system are disclosed for interpreting dips, dip trends, and mineral based lithofacies data to identify certain geological events in a subsurface formation. The disclosed method/system analyzes dip magnitude and azimuth data to determine the dip trends in the formation. The dip trends are then examined for indications of the presence of certain depositional events, such as build-ups, flow directions instances of scour and fill, direction to thalweg, parallel bedding, indications of fault, and the like. If lithofacies data is available the disclosed method/system can also analyze this data to identify the presence of interbedded sequences and condensed sections. Such an integrated solution saves geoscientists and interpreters an enormous amount of time compared to existing interpretation techniques, allowing them to be much more productive. The disclosed system/method may also be used to help train new and less experienced geoscientists and interpreters.

Method and system for interpreting borehole geological data

A rock classification system involves the use of a Ternary Diagram (TD) Model and a set of rules in a rule base. A computer, which stores a rock classification software which includes the rule base, will be responsive to certain data points from a Spectroscopy Sonde, will compare each data point with each of the rules in the rule base, and, when a match is found, will generate a specific rock classification for that data point. When a plurality of data points are input to the computer, a corresponding plurality of rock classifications are generated.
