Oil & Gas Upstream

Subsurface Consulting & Mapping Analysis

Building reliable estimates and forecasts based on correct data, consistent interpretation

In the oil and gas industry, fortunes can be made or lost based on a company’s ability to anticipate where hydrocarbons are located in the ground and what it will take to recover them. The ability to make smart, confident decisions about exploration and production investments often depends upon access to accurate data and analysis from experts with a proven track record.

The upstream oil and gas consulting team at IHS Markit can help you optimize development of your company’s in-ground assets. We specialize in addressing complex reservoir situations by providing integrated subsurface consulting and mapping analysis solutions for:

  • Reserve and resource evaluation and auditing
  • Reservoir engineering & simulation
  • Geological studies
  • Reservoir development, production engineering, and asset optimization
  • Gas gathering system modelling
  • Well-test analysis field development planning and concept selection
  • Expert testimony

Disciplines

Our ability to address the full spectrum of reservoir situations is based on the breadth and depth of IHS Markit expertise. We generate best-in-class exploration assessments, greenfield/brownfield development studies and large reserve evaluations by bringing together the technical skill sets of consultants from:

  • Geology
  • Geophysics
  • Petrophysics
  • Reservoir Engineering
  • Reservoir Simulation
  • Reserves and Economic Evaluation
  • Well Testing
  • Wellbore Modeling
  • Pipeline Modeling
  • Development Planning
  • Uncertainty [Monte Carlo] Assessment

For each project, subsurface consultants from relevant disciplines develop an understanding of the available datasets and the conclusions that can be drawn – e.g. geology from regional studies, geophysics from seismic data, petrophysics from core and log data, reservoir engineering from production data, etc.

“Consistency of interpretation” is the hallmark of quality for the IHS Markit subsurface consulting team. We can optimize the reliability of our integrated analysis for investment and reporting purposes by ensuring that each discipline’s interpretation of the data is consistent with the core dataset as well as the analytic approach of the other disciplines.

Deliverables

Our subsurface consulting services are flexible and scalable to your needs. We support projects as small as a single well test analysis or wellbore model, or as large as a pool, field or offshore concession for well and facility optimization studies, exploration assessments and greenfield/brownfield developments.

The starting point for all of our subsurface projects is data gathering and rigorous quality control. Accuracy is essential, especially when data availability is limited. Something as simple as an off-depth perforation interval or an incorrectly reported pipeline operating pressure can invalidate any analysis, particularly if it is the only data point you have on hand at the time of the study.

Once we have obtained the best available data, IHS Markit experts from multiple disciplines deliver subsurface consulting and mapping analysis via:

  • Estimates of hydrocarbons-in-place, recovery factors and recoverable volumes
  • Forecasts of production rates and ultimate recovery, which become inputs for economic value assessments, exploration and development plans as well as the de-bottlenecking and optimal operation of producing fields and entities

Industry Success Stories

North Sea operator continues strong production based on waterflood simulation study insights

When its offshore rigs reported increasing water-cut, a North Sea oil producer wanted to know if the ratio of water production would plateau. IHS Markit evaluated a third-party geological study and developed a waterflood simulation that identified the cause and suggested that the firm could continue to achieve strong oil recovery performance. As production proceeded, this forecast proved accurate.

Oil field producer optimizes pipelines to reduce wellhead pressure and sell casing-head gas

A leading energy company wanted to reduce wellhead pressures and capture casing-head gas by improving its oil gathering pipeline network. IHS Markit created a pipeline model, identified the location for a pumping station and found a pipeline bottleneck. When the energy company implemented our recommendations, it was able to successfully capture and sell the casing-head gas.
