Operations Geology

Petrophysical Evaluation aims to reveal the reservoir rock and fluid properties using Well Bore logs, mud logs, cuttings and core data. The Petrophysical Evaluation is a key input for building a reservoir geomodel.

GeomodL can perform swift petrophysical evaluation for clastics and carbonates reservoirs.

Operations Petrophysics starts with the creation of the data acquisition plan as part of a Well Proposal. Closer to spud, the Data acquisition evolves into a logging program.

During the actual data acquisition process, constant monitoring is required to ensure that the data get properly acquired. Following the acquisition, a quick look evaluation is performed which will serve as basis for the final data interpretation and after action reviews.

GeomodL can assist you with the drafting of your data acquisition plan and logging program, Monitor your logging activities, perform quicklook and final interpretation.

GeomodL can provide technical support for logging contract tendering process and contractor performance management.

Our expert is also available should you need to consolidate your petrophysical database.

Understanding the reservoir is the key for an effective and efficient oil and gas field development. Reservoir concepts are the starting points of Reservoir Models and ultimately enable robust development decisions.

GeomodL provides Geological services aiming at understanding your reservoir using “all the available data” including:

• Core description and interpretation
• Geological data mining and analogue study

Integration with other subsurface disciplines to consolidate the understanding of the field and ultimately defines the critical reservoir features worth modelling.
Seismic Data offers valuable insight of the reservoir and is, most of the time, the only 3D data available to understand the reservoir. Seismic interpretation transforms the seismic waves information into usefull data inputs for Subsurface models and help nurture the understanding of the reservoir. Often the seismic intepretation process involves a close interplay between geological concepts (Geology) and physical theory behing the seismic response (Geophysics).

Together with our strategic Partner Ires-Geo, GeomodL can offer the following geophysical services:

• 2D / 3D seismic interpretation
• Time to Depth Conversion
• Block Evaluation / Prospect Maturation
• Seismic attributes analysis
• 2D / 3D seismic inversion
• Spectral Decomposition
• Reservoir Sweet Spotting
• Seismic 4D feasibility and analysis

Model Framing is a must do that consists in defining (framing) the reservoir modelling effort with the business objective, the data available and the resources at hand prior to embarking on a reservoir modelling exercise.

This short, focus and integrated service allows the team to define the most efficient workflow for your Reservoir Model. Our expert can supervise and frame your subsurface team to define the best workflow, the corresponding workscope and inputs needed, the QC steps and the timeline for your Reservoir Modelling exercise.

GeomodL can assist you to choose the best workflow to construct your geomodel.

An initial step by step workflow can be generated taking into account your data limitation, your time and resources constraints
Follow up progress checkpoints can be organized to check progress and provide guidance / steering if required.

GeomodL expert can be based in your office and provide continuous software support during your Geomodelling exercise if you want to know which method to use for performing an action in your Geomodelling workflow or simply do not know which “button to push”, our expert, sitting near you, is available any time of the day to guide you through the multiple options proposed by the software.

GeomodL help you to prepare and set for success your drilling activies. Our expert can assist with Well deployment strategy, Well Picking, Well Proposal and Well Functionnal Specs, Geological Prognosis, Pore Pressure Prediction, Well Trajectory Session and Data Acquisition.

Our expert can generate a valuable Geo-Operational Plan which allow you to stay on top of your drilling activities. The Geo-Operational Plan covers all the subsurface aspect of your drilling operations:

• Well objectives definition: a set of ranked well objective helping you focus on critical answers
• Data Acquisition plan: a synthetic document grouping the data acquisition requirement to fullfill the well objectives
• TD criterias: a clear and concise matrix for each section to call TD based on several criterias used to determine TD
• “What-if” scenario: the mapping out of possible scenarios during drilling (ex: losses, shallower reservoir, etc…) and their corresponding course of actions to stay ahead of time and boost-up readiness. The target of the what-if scenario is to avoid costly last minute rush decisions

GeomodL can provide Wellsite and office based geologists to supervise the drilling of your well and report every significant developments.

Our expert can assist in monitoring the progress of the well, pick section TD, perform Active / Passive Geosteering in the reservoir, oversee and advise during data acquisition phase.

GeomodL can compile the Post Drill Report and coordinate with the contractors the transmission of final data and the archiving

Our expert can help you capture the subsurface learnings of the well via a subsurface After Action Review where Post-Drill actual data are set against Pre-Drill predictions.

Post drill Volumetrics update and Pre-Drill / Post-Drill reservoir model comparison can be done and communicated to your stakeholders.
