Which modules are you? ©

Techlog is designed in a modular fashion and companies or users can choose the ones to which they want to have access. Users have the ability to condition the menu system used in Techlog to suit their own working style. Unused functions can be hidden; used functions can be grouped just the way you like. Customised systems can be saved at Company, Project or User level. There is a licensing strategy that is easy and flexible. Pick and choose modules to suit your needs.

Import, view and manage core data from anywhere

Tco SHM

Locate user data

Generate inventories

Within countries, fields and wells, search for data with complex search filters. Filters can use data values as limiting criteria, e.g. porosity > 0.2.

Filters execute complex queries to organise the data; queries can be saved for re-use.

Q

Tables are easily compiled with core results data and experimental conditions data. Click on a report document to see its associated

plug data highlighted. Create mono-well or multi-well inventories by grouping core information through the query tools.

Keep audit trail

There is full user access to pre-defined standard plot templates, with full customisation of plots, histograms and logs. Plots, with their associated data, may be exported to Excel spreadsheets.

A click on a sample in a table brings the core images into view; click on the image to see photos of core plugs listed; click on the core plug picture brings the plug information table. View core images at low and high resolution.

CoreDB (CDB) keeps user activity history that can be accessed from the administrator console. See when data were uploaded, by whom, and whether any edits have been performed.

Pore network and fluid distribution Tco SHM T2 Conversion: data “regularisation”

Toolbox

• Adjust the T2 data into a single data range and a single number of bins across that range, irrespective of tool source. The application is designed to accept all industry T2 distribution data and to convert them into a regularised T2 distribution

• Compute porosities, permeabilities, water and hydrocarbon volumes through an intuitive user interface; the results can be displayed immediately and controlling parameters/functions adjusted graphically if necessary

Q Q.m TBA Nmr FP°

• Using the clay-bound water (CBW) cut-off (from constant or curve), the NMR clay-corrected porosity and the CBW volume are computed. The Free-Fluid-Index (FFI) cut-off is used to compute the hydrocarbon volume. The total porosity is an integration of the regularised T2 distribution • Two estimates of permeability, the Coates and SDR permeability, are automatically computed from standard equations whose parameters can be again curves or constants and can be adjusted graphically if necessary
