Heavy Oil

Massive reserves, technical challenges, and huge rewards

Some of the world’s largest reserves are heavy oil reservoirs. With oil in place equal to the largest conventional oil fields in the Middle East, heavy oil reserves are found in more than 30 countries around the globe.

Our focus is improving the development and exploitation of deposits in existing heavy oil regions and increasing recovery from underdeveloped deposits. This requires balancing economics and reducing the energy requirements and environmental footprint of producing these reserves.

Modern sample analysis laboratories located around the world provide rapid, accurate rock and fluid property information

Heavy oil resources are twice those of conventional oil.

The main challenge of heavy oil is not finding the resources but in extracting, recovering, producing, and selling heavy crudes within often changing economic guidelines. To bring these extensive reserves into economic viability, all parameters, disciplines, and personnel need to be optimized to work in perfect sync for exceptional operations. We have the expertise and technologies to cover all the reservoir, drilling, completions, and production bases and bring heavy oil recovery within practical reach.

Software

Model reservoir geology and flow with expert interpretation and consulting.

Once EOR methods have been deployed, planning and implementing the most efficient strategy for full field development requires good quality data, expert analysis, and regular review. Overall project economics can be significantly enhanced by accurate modeling with the industry's most diverse portfolio of software solutions.

VISAGE finite-element geomechanics simulator

VISAGE simulator provides a comprehensive system for geomechanical analysis on a reservoir scale. Stresses and strains are calculated in a consistent manner across the reservoir, the overburden, and the surrounding environment. Coupling VISAGE simulator with ECLIPSE industry-reference reservoir simulator ensures the interaction between mechanics and fluid flow is fully accounted for, including the effects of faults and fracture sets.

INTERSECT Thermal high-resolution reservoir simulator

INTERSECT Thermal enables accurately modeling the thermal recovery methods typically used in heavy oil and bitumen reservoirs to reduce the high oil viscosity by increasing the temperature. Thermal recovery processes that can be simulated include steam-assisted gravity drainage (SAGD), cyclic steam injection (huff ‘n’ puff), steamflooding, steam-solvent, hot water injection, and wellbore heaters.

OLGA dynamic multiphase flow simulator

OLGA simulator models time-dependent behaviors, or transient flow, providing an added dimension to steady-state analyses by predicting system dynamics such as time-varying changes in flow rates, fluid compositions, temperature, solids deposition, and operational changes. The OLGA simulator enables key flow simulation applications, including liquids handling; sizing separators and slug catchers; managing solids; simulating key operational procedures including startup, shutdown, and pigging; modeling for contingency planning; and assessing environmental risk in complex deepwater drilling environments.

Reservoir Description

Plot out a target-by-target production strategy.

Generally, heavy oil targets are known with depths identified and a general idea of the API gravity. So the key question is, which target within a field do you evaluate first?

The technical challenges in preliminary evaluation of heavy oil are often related to accurately understanding the reservoir geology, petrophysics, and geomechanics. This knowledge helps to evaluate, model, and simulate various EOR methods to determine which would provide the best results, with minimal environmental impact. By understanding key reservoir characteristics, you can better predict fluid flow and ultimate recovery volume. With this information, you can prioritize and further evaluate your asset using concept-to-full-field methodologies to ensure the best-possible ROI.

Well Construction

Accurately place and construct your producer, injector, and monitor wells.

There are three main objectives when constructing and completing heavy oil wells: accurate well placement, wellbore stability and longevity, and production efficiency. Typical heavy oil fields will likely undergo thermal recovery, but some operators are piloting and evaluating alternative hybrid thermal-solvent recovery methods, such as gas- or solvent-assisted methods, to reduce energy demands of production. Careful consideration must be given to applying technologies that will yield the most value.
