Services

Various elements help us understand Geopressure in an area

  • Reservoir

    What do reservoir pressures locally and regionally tell us about your reservoir? Analysis on a local and regional scale to understand vertical and lateral connectivity

  • Seal

    What lithology is our seal? What is its fracture strength? Is the seal effective elsewhere? What controls it’s effectiveness? Does it vary spatially? How much pressure can it support?

  • Overburden

    What is the geology of the overburden? How much load does it exert? Where in the overburden does overpressure exist and how does it relate to our reservoirs?

  • Burial History

    How fast was burial? Has there been uplift? What controlled overpressure build-up? How hot are the rocks? All these questions and more can affect present day pressures.

  • Drilling Experiences

    Drilling Experiences

    How was each well drilled and what does this tell us about pore pressure? What were the mudweights, casing points, Leak-Off Tests? Were kicks or losses taken? What drilling gases were experienced? What issues occurred whilst drilling?

Bespoke Services to meet your needs.

Discuss and agree a scope of work. Analysis may include the following

  • Reservoir Overpressure Mapping

    Focus on reservoir pressure data. This is our primary data source, and from this we can understand lateral and vertical connectivity, baffles and barriers on a local to regional scale. Identify areas of high and low overpressure, faulted controlled compartments, draining systems and their leak points, isolated reservoirs, effects and extents of depletion, key internal baffles and barriers, the potential for kicks.

  • Well Planning

    Use the most relevant offset well data to understand the likely hydrostatic, formation, fracture and overburden pressure at a prospect location.

    Understand risks pre-drill to aid well design, or in the case of Carbon Capture and Storage, how the prospect will perform during injection.

  • Seal Capacity Analysis

    Focus on reservoir-seal pairs.

    How strong is the seal at your prospect and how has the seal performed in nearby and regional analogues?

    Does leakage or column height relate to pore pressure?

    What are the main risk factors?

  • Regional / Field Scale / Local Geopressure Studies

    Understand the whole pressure system from shallow to deep, what has controlled it’s development and how affects prospectivity and risking.

    Assess small areas or large regional datasets. Include seismic, structural interpretations and facies distributions to get the most out of your data.

  • Database Creation

    Locating, collating and organising data from wells is part of the day job. This means that highly valuable databases can be created efficiently and accurately allowing the maximum potential to be extracted from them.

    This might be a regional database of pressure data, Leak-Off Tests, mudweights, kicks and more.

  • GIS Analysis

    Professional manipulation of data and map creation to enable efficient display of large or small datasets.

    Get your deliverables as shapefiles for use on your internal systems.

    Take advantage of a large in house database of collated published structure and facies maps from literature, publications, relinquishment reports and well reports.

  • Post Drill Analysis

    Get a professional second opinion on the pressures experienced in previously drilled wells.

    What are the alternative interpretations?

    Can any learnings be taken forward to the next targets?

  • Decommissioning & Abandonment

    Assess the different pressure regimes in wells ready for abandonment by using offset wells and local/regional understanding.

    Analyse which formations may have potential to flow into the borehole to aid plug placement.
