IRT offers technical petroleum reservoir management consulting services to the worldwide petroleum industry. We specialize in providing reservoir simulation studies and integrated multi-disciplinary studies to solve our clients' reservoir development problems. These studies typically involve some or all of the following services:
and of Primary, Secondary, and Integrated Reservoir Management Integrated Reservoir Management uses all IRT's services to splice the diverse pieces of a technical puzzle together, leading to the most accurate possible description of the reservoir, prediction of its performance and optimization of its economic depletion. Ongoing gathering of reservoir specific data, including continuing production, new wells, etc.,can be used to update that description to fine-tune the performance predictions and optimizations, thus providing a valuable reservoir management tool. Numerical Reservoir Simulation  Numerical reservoir simulation is well proven as the most accurate means of understanding the production history and predicting future well and reservoir performance. IRT's engineering staff has extensive experience in single-well, cross-sectional, sector-models, and full-field reservoir simulations using a variety of commercially available software. IRT has a geophysical staff with extensive experience in the latest techniques and software for seismic interpretation. Seismic data can be used in conjunction with well data, regional geology, surface maps, and other data to develop accurate interpretations of the reservoir structure and any associated faulting. These interpretations can be used for exploration and reservoir development. Seismic attribute analysis can also add to the understanding of the distribution of the reservoir physical properties. IRT has staff experienced in structurally complex regions including extensional, compressional, and strike-slip environments. IRT has geological staff trained with software packages that allow for structural restoration. In addition, our geophysical staff is trained to use 3D visualization and interpretation software to develop accurate structural models in the most complex settings. Structural models, fault-seal analysis, and seismic sequence stratigraphy assist in understanding complex reservoir compartmentalization. Structural Cross Section IRT's geological staff and associates have extensive experience in core description. Accurate core description can be critical to understanding the reservoir's depositional environment, petrophysical properties, and reservoir characterization. Also, accurate characterization of fractured reservoir environments usually begins with close examination and description of the core. IRT's geological staff is experienced in the latest techniques and software for facies identification and stratigraphic interpretation. Stratigraphic interpretation can be critical to understanding the distribution of hydrocarbons and productivity within a reservoir. Regional geology, logs, seismic interpretation, and sequence stratigraphy, as well as core data and description are used to reconstruct facies distribution to develop a depositional model. Stratigraphic Cross Section IRT's petrophysical team has vital experience in the latest techniques and software for petrophysical interpretation in single and dual porosity systems. IRT supports both traditional and neural-net modeling. IRT also has ongoing relationships with senior petrophysical associates who can assist in these complex studies. Petrophysical analysis is key to determining depositional environment, effective in-place hydrocarbon volume(s), and productivity. 
Geostatistics and Heterogeneity Modeling IRT has significant experience in the application of geostatistical methods of heterogeneity modeling. Moreover, IRT is accustomed to working with large conditioning datasets of 100 or more wells. Geostatistical techniques often provide a more accurate representation of the internal reservoir architecture by properly modeling the spatial distribution of reservoir facies and capturing the spatial variability of the reservoir properties. Many of these techniques being stochastic in nature allow us to explore the uncertainty in the reservoir description (e.g., volume, connectivity) by generating multiple realizations. The realizations can be analyzed to assess risk and to improve reservoir management.
IRT's engineering staff has extensive experience in the latest techniques and software for hydrocarbon characterization. Accurate description of characteristics and behavior of the hydrocarbons is very important to understanding and predicting the production performance of the reservoir. Equation of state calibration for both compositional and thermal studies is a special capability of IRT staff. In addition to reservoir pressure determination, individual well test analysis can be used in the design of fracture treatments, artificial lift design, and the analysis of coning, as well as the analysis of damage and natural fracturing. IRT has several engineers on staff that have experience in the latest techniques in well test analysis by conventional means, as well as with the integrated reservoir simulators to explore fracture networks and interference. Full-Field Geocellular Static / Dynamic Model To properly assess possible operating strategies, it is usually necessary to evaluate the economic impact of those strategies. Using simulation-based forecasts of production streams, and cost estimates for new wells, facilities, etc., each potential operating strategy can be evaluated economically to determine the most optimum depletion strategy to employ in a reservoir. In conducting its studies, IRT encourages participation of client staff. This participation provides hands-on training within the staff-member's area of interest, using the client's own reservoir(s). This transfer of technology can have long-lasting benefits to the client. IRT can tailor similar training in a course-like environment for a client that is not dependent on conducting any particular study. Additionally, IRT staff have conducted training courses for many of the world's largest energy companies in various aspects of reservoir engineering, reservoir simulation and enhanced oil recovery. IRT currently offers two courses, building a reservoir static model and reservoir simulation that are taught at various times throughout the year or as an in-house class as requested. In some cases, clients find themselves in need of credible independent technical expertise to defend their positions in legal proceedings. Because of IRT's high level of experience, our analyses and testimony as expert witnesses can lend substantial credibility to a client's position. In some cases, clients find themselves in need of expert opinions on technical subjects that may not be related to any specific reservoir. IRT's experienced technical staff may be able to help. Examples of this type of service include comparison of software alternatives; recommendations for appropriate software/hardware purchases for the client's internal use; recommendations for technical approaches for internal studies; EOR screening studies; assistance in supervision, management, and conduct of internal studies; and others. |
