LogScope is a new generation package that works locally on the following platforms:

  • Windows devices

  • iOS devices including iPhone

  • MACOS devices

 

The software allows:

  • WITSML streaming

  • OSDU access

  • Mapping

  • Cross sections

  • Data Editing 

  • Petrophysical Interpretation

  • Geomechanics

  • User equations

  • Python Scripting

  • Data Display

  • Cross plots

  • Depth indexed plots

Modules in LogScope
LogScope is easy to use and works on a Windows, iPad and iPad Pro tablets.
​
Users say " It was fabulous for monitoring LWD results and picking TD at 3 am in the morning. Easy to use."  

"I'm extremely pleased with the LogScope package."
Data Structure

 

The data is stored locally on device and leverages the security features of iOS and Windows 10 architecture to keep the data secure. The data can come from any source and archived remotely from any cloud based or web accessible data base. Some examples include OSDU, Well to Desk and various WITSML vendors.

 

Standard LAS, DLIS and CSV files can be loaded directly from email, disk files or web links.

 

Sample rates are honored and discrete data, array data and high-resolution information can be stored locally. All metadata such as header, logging run properties and formation tops are stored locally as well.

Editing

 

LogScope has the following editing functions:

  • Trim

  • Merge

  • Patching

  • Depth Shifting

 

From any plot, the user can graphically trim  selecting top and base of log interval to keep. This trim function can also expand the various groups in LogScope. 

​

Data from external DLIS, LAS files can be directly merged into existing data sets. Curves can be composited or changed by copying from individual groups within a well to other groups. Mixed and discrete sample rates are handled as LogScope intelligently copies curves appropriately.

 

The graphical Patching function allows curves to be interactively digitized using Mouse, Apple Pen or Finger. Artefacts such as tool pick up can be removed quickly from a curve.

 

Both rubber band depth matching and linear depth matching (one depth shift) which can be applied across multiple curves and baseline curve shifting are available. The latter being suitable for Spontaneous Potential drift correction.

 

The data view in LogScope allows individual values to be edited on the fly simply by clicking on the value and editing it.

 

LogScope has a vast unit conversion data base so recognizes most units used.

Petrophysics

 

LogScope performs complete petrophysical processing and any or all of the following can be processed:

  • RT/RXO

  • Gamma correction

  • Density Correction

  • Neutron Correction

  • Bad Hole Flag

  • Vclay

  • Apparent porosity

  • Spectral Gamma

  • Mineral

  • Apparent Water resistivity

  • Total and effective porosity and Saturation

  • Lithology from various models

  • Pay flags

  • Rock Mechanics

  • Unconventional Reservoirs

  • Coal Bed Methane

  • Cased hole Sigma

  • NMR T2 distribution to porosity and clay

 

LogScope preserves the original input data and creates a Group with all the updated curves and output data.

 

The mud properties stored in the well header are used to compute the mud properties along the well bore. 

 

LogScope has four models which include a basic deterministic, complex lithology, silt, shale, sand model and a dual water model. The flexibility allows parameters and curves to be used as inputs for additional Python scripted models.

 

LogScope has a sophisticated geomechanical computation module as well as ability to handle Unconventional reservoirs and coal bed methane computations.

 

LogScope allows different models to be used for different zones in a well and also provides the ability to different models for facies zones. For example, coals can be identified and the gas volumes computed in one pass.

Display

 

LogScope allows single well plots to be constructed using components that include:

  • Depth track

  • Curves

  • Curve shading

  • Arrays

  • Photographic images

  • Tadpole plots 

  • Polar plots 

  • Alphanumeric curve data

  • Discrete data

  • Formation Tops

 

The plot set up can be saved as user defined templates and exchanged between devices and users.

 

Cross plots can be created using three curves and sized and stored as defaults. Predefined cross plots that include matrix lines and other signifying features are also built and can be accessed by the user quickly and easily.

 

User defined depth index plots related to the cross plot is available and points can be highlighted on either to show the points or interval of interest. 

 

A simple Deviated plot is also available which allows the attitude of the well to be shown. 

 

The Map view allows wells to be displayed spatially and leverages the mapping capabilities in the respective Windows and iOS environments.

 

Lines of Sections can be fixed distance fence, projected or scaled and can use any datum such as a zone or formation top. They can be scaled in true vertical depth or depth subsea.
