Integrated Reservoir Solutions via the OpenWorks database

Landmark Graphics provides a complete integrated reservoir characterization and management solution which covers the entire oil field life cycle. The components include geological and geophysical interpretation, petrophysical analysis, reservoir engineering (reservoir modeling, visualization and simulation), project data management and economics. Applications interact directly with the OpenWorks database, providing rapid access to the latest interpreted information.

PetroWorks

PetroWorks provides the fundamental log analysis tools needed for well data evaluation. Its multiwell, multizone capabilities are inherent in the softwareÕs design, providing for smooth transitioning from single well to field-wide studies. Included in its capabilities are graphically-based well log editing, environmental corrections, and a variety of deterministic interpretive models, including 3 and 4 mineral solutions. A sophisticated crossplot application, with data interaction between the crossplot, log plots and histograms, provides a flexible and intuitive approach to determining reservoir parameters on a zonal or field-wide basis. User programming is available to meet the needs for unconventional interpretation. A full-featured mapping module is also included to aid field studies for the petrophysicist or interdisciplinary team. PetroWorks is tightly coupled to the OpenWorks database, and is tightly integrated with StratWorks and Wellbore Manager.

PetroWorks Advanced

Specialized petrophysical interpretation, including stochastic analytical techniques, is provided by this suite of applications. These five products and the associated data handling utilities are developed by Western Atlas Logging Services and are integrated into the Landmark environment. The capabilities include Optima (probabilistic implicit interpretation,), Horizon (probabilistic explicit interpretation), Wave (acoustic log processing), Stratagon (dipmeter interpretation), and Vision (borehole image analysis).

LogEdit

LandmarkÕs log editing capabilities, integrated into the PetroWorks environment, are also available separately for those who donÕt require the analytical capabilities of PetroWorks. LogEdit allows the user to edit log and core data by graphical and manual means. Features include depth shifting, filling gaps, modifying measurement values, and merging data from different logging runs.

Included in LogEdit are the computational capabilities of MathPack, Unit Editor for the creation and modification of subsurface zones, curve management capabilities of Curve Utility, and graphical and text reports.

Wellbore Manager

Designed for both Geoscientists and Engineers, Wellbore Manager is an integrated application for incorporating well-mechanical data into interpretive workflows. Wellbore Manager builds, manages, and visualizes wellbore mechanical, image data and log curves. Extensive interactive functionality for creation, editing, updating, and management of well equipment, completion, and activity information easily provides up-to-date data to all asset team members. Wellbore Manager diagrams are instantly available for use in LandmarkÕs cross section, mapping, and petrophysical applications through the OpenWorks framework.

StratWorks

StratWorks integrates the interpretation of surfaces, faults, and reservoir attributes from both well and seismic data through tight interaction between detailed cross-sections and map windows. Log correlation is streamlined through innovative methods for overlaying well logs, and precisely picking tops, faults, and other geologic events. Well events are shared between PetroWorks and StratWorks to support integrated geologic and petrophysical interpretations. A common Well Display Template Editor with PetroWorks allows you to easily display log curves and other well information. StratWorks mapping capabilities (also shared with PetroWorks) enhance workflows by providing surface, attribute, and isochore modeling as well as basic basemapping capabilities. Bubble and Pie map displays can also be built. StratWorks results are available to other E&P applications through the OpenWorks database.

SynTool

SynTool is a powerful, easy-to-use application that allows you to accurately tie well events and lithologies with seismic data. Whether in need of a quick synthetic seismogram for a currently drilling well or a detailed prediction of reservoir properties away from an existing well, SynTool provides an extensive and robust set of modeling and analysis tools to improve your interpretation. Under the OpenWorks framework (shared with other Landmark geological and geophysical applications) you can access sonic and density curves, checkshot surveys, tops, and other well data quickly and easily. SynTool handles all your checkshot, TVD, and datum corrections, lets you edit or generate impedance data, and extracts wavelets from your seismic data using several methods. Synthetics can be displayed on your seismic sections with the click of a button, and correlation diagrams help you assess the quality and validity of your synthetic tie.

LOGIC GROUP (THE)

Log Interpret

This is a standard log analysis program, using many of the basic algorithms from the ADVISER series. Results are presented in tables and graphs. A net pay screen summarizes the results of analysis

ADVISOR SERIES

A system of programs with a series of modules: SSA (Shaly Sand Adviser)- analyzes well logs from shaly sands and includes several methods to compute clay volume, porosity, and water saturations; CBA (Carbonate Advisor)- determines lithology, pore type and hydrocarbon presence from cross plots, and computes porosity and lithology volumes. Various M models available for estimating water saturations; OEA (Old Electric Log Advisor)- provides an interactive environment for estimating true resistivities from the laterolog, short and long normal curves. Cross plots are provided to help find hydrocarbon presence; DSA (Devonian Shale Advisor)- analyzes well logs from organically rich shales using four component analysis of quartz, heavies, kerogen, and clay.

PLAN PLUS

Plan Plus is a windows based program that allow users to planimeter contour maps that are input using a digitizing tablet. Contour areas and volumes are easily computed. Both English and metric units are available. Additional features include computation of wellbore drainage from volumetrics, volume from digitized top and bottom structure maps, 3-D graphics displays, discretizing contour values based upon user defined grids, and hardcopy output of maps to user set size. New features include DXF interface to enter maps to AutoCAD and display of well bore from survey data.

LOGPRO GEOTECHNICAL SERVICES

TGS LogPro

An advanced log analysis software for tight gas sand applications and laminated shaly sand gas reservoir applications. The software can be used on either a PC or on a Macintosh. The choice of platform is more or less transparent. A framework of nine linked and integrated modules provide full functionality for data input, data editing, unit conversions, data discrimination, environmental corrections, histograms, data normalization, crossplots, statistical analysis, constant determination, log computations, zone summations, traceplots and tabular output.

TGS LogPro models a density-neutron derived water saturation in the "near-wellbore zone". This leads to the identification of flushed, permeable zones and unflushed, tight zones. There are additional advantages to this approach, for instance a fully gas-corrected porosity. Also, since the DN saturation is independent of resistivity, it results in a logic to interpret Rw in unflushed zones, thereby improving the accuracy of resistivity-derived saturations. Crossplot and traceplot methods are used to determine and verify the critical and sensitive constants. Results are therefore accurate and reproducible.

TGS LogPro includes a sonic-neutron model for laminated shaly sand gas reservoir applications. Also there are advanced models for analysis of the SP log, CMR and MRIL. Software documentation includes an introductory text, a user's manual and an example analysis of a tight gas sand well.
