	CASINGCK – Casing Stress Check Model designs and verifies casing strings using the latest verification methods. CASINGCK compares the resistance of a casing column design to the stresses that the column will experience. A variety of potential stress factors are considered.
	CEMENT – Wellbore Cementing Model is a powerful and easy-to-use engineering tool for comprehensively analyzing the complex phenomena of multistage fluid placement in a wellbore and is a very useful planning tool prior to field operations.
	CENTRA – Casing Centralization Model is an easy-to-use tool for computing centralizer spacing to provide sufficient stand-off between casing strings and the wellbore wall.
	CTLIFE – Coiled-Tubing Fatigue Life Model predicts fatigue failure caused by cyclical plastic bending of coiled tubing (with and without internal pressure) during field operations.
	CTPRO – Coiled-Tubing Professional Package is a complete coiled-tubing job design software package used for planning CT field operations.
	CWEAR – Casing and Riser Wear Analysis and Prevention is the industry-standard analysis tool for predicting and monitoring casing and riser wear due to rotary contact of drill pipe with tubulars and other downhole elements.
	DDRAG – Torque and Drag Analysis Model is a field-proven engineering tool that analyzes the complex phenomena of axial and torsional loads, and the development of torque and drag (and buckling) of drill pipe as it is run into the hole (slacked off) and pulled out of the hole (picked up).
	DPLIFE – Drill-String Fatigue Life Model predicts and helps prevent drill-string fatigue failure. Two mechanical models are included: fatigue and crack growth.
	Driller's Toolkit™ for Desktop PC is a convenient collection of more than 100 drilling engineering tools. This useful package is available for desktop/laptop PC or for Pocket PC (see below).
	Driller's Toolkit™ for Pocket PC includes more than 100 drilling engineering tools in an extremely convenient hand-held package for use in the field.
	GTEMP – Wellbore Thermal Simulation Model is a thermal simulation program for predicting wellbore temperatures. The program models natural and forced convection, conduction within the wellbore, and heat conduction within the surrounding formation.
	HTHPFLOW – High-Temperature/High-Pressure Hydraulics Model determines the effects of high temperatures and pressures on rheological properties of drilling/completion fluids.
	HYDMOD – Wellbore Hydraulics Model is the drilling industry’s premier engineering program for comprehensively evaluating fluid hydraulics for drilling, completion, and workover operations.
	MUDLITE – Air/Mist/Foam and Flow-Drilling Hydraulics Model is a world-class engineering tool for planning and analyzing air/mist/foam and flow-drilling underbalanced drilling and completion operations.
	NITRO – Nitrogen Cost Analysis analyzes nitrogen costs for underbalanced operations. The primary purpose is to help in the decision-making process for selecting a nitrogen generation method.
	PORE – Abnormal Formation Pressure Detection and Estimation Model estimates pore, fracture and overburden pressures. It makes use of Pennebaker plots to determine formation pore pressures from seismic stacking velocity data.
	RESMOD – Horizontal Well Reservoir Model is a screening model that allows quick comparison of production from different types of wells in specific reservoirs. Results are used as an initial screening of candidates to save time and money in reservoir evaluation.
	TRIAX – Triaxial Stress Analysis Model calculates limits for burst and collapse pressures and equivalent stresses for the pipe body due to specific operational environments.
	WELLCON – Well Control and Kick Tolerance Model assists drillers in controlling gas kicks. It describes complex multiphase flow that develops as a gas influx is circulated out of the well.
	WELLPATH – Wellpath Planning and Projection Model is the most sophisticated software application available in the oil industry for generating wellbore surveys. WELLPATH manipulates well trajectory data including: survey data input, survey data editing, wellpath planning, wellpath projection, trajectory comparison, and checking well collisions.
	WELLSTAB Plus – Wellbore-Stability Analysis Model analyzes mechanical/ chemical stability of vertical or inclined wellbores and can be used prior to actual field operations. A linear poro-elasticity model is used to predict wellbore stability and ranges for stable mud weights or wellbore pressures.

We offer programs for every step in the well-planning process.
