In reservoir engineering, hydrodynamic properties can be estimated from downhole electrical data using heuristic models (e.g., Archie and Kozeny-Carman's equations) relating electrical conductivity to porosity and permeability. Although proven to be predictive for many sandstone reservoirs, the models mostly fail when applied to carbonate reservoirs that generally display extremely complex pore network structures.

In this article, we investigate the control of the three-dimensional (3-D) geometry and morphology of the pore network on the electrical and flow properties, comparing core-scale laboratory measurements and 3-D x-ray microtomography image analysis of samples from a Miocene reefal carbonate platform located in Mallorca (Spain).

The results show that micrometer- to centimeter-scale heterogeneities strongly influence the measured macroscopic physical parameters that are then used to evaluate the hydrodynamic properties of the rock, and therefore, existing models might not provide accurate descriptions because these heterogeneities occur at scales smaller than those of the integration volume of the borehole geophysical methods. However, associated with specific data processing, 3-D imagery techniques are a useful and probably unique mean to characterize the rock heterogeneity and, thus, the properties variability.

Lateral thinking is something we can all employ, whether freshly minted graduates or seasoned veterans looking for the next career move. In fact, it’s common in our cyclical industry that petroleum geoscientists have to pivot, change and reorient to launch and advance their careers.

Explorer Historical Highlight

 

The Ayoluengo field was the first commercial oil discovery in Spain and more than 50 years later remains the only onshore oilfield in the Iberian Peninsula. The field was discovered in 1964 and is still producing.

The Ayoluengo field, commonly cited as Spain’s only onshore oil field, was discovered in June 1964. Today, 50 years later, the field is still active, with an average production of some 100 barrels oil per day and a total cumulated oil production of nearly 17 million barrels of oil.

Participants will examine illustrative outcrops of thrusts, fault-related folds, stratal architectures and facies of depositional systems affected by growing structures, which are good analogues for hydrocarbon reservoirs. Objectives include interpreting complex thrust structures, identifying and understanding strain and fracture systems in fold-thrust belts, and analyzing patterns of growth strata in areas with synsedimentary folding.

The field trip will include stops at Shumard Canyon and Bone Canyon to observe the scale and internal architecture of submarine channels incising the bedrock of the relict platform. Other field-trip stops will include Stratotype Canyon, Black Stove Canyon, and Rest Area Gully to observe basin-restricted carbonate and siliclcastic sediment gravity flow deposits, carbonate channel-levee complexes, failure scours associated with the downslope transport of olistostromal blocks, and thick (>50 m) accumulations of recumbently folded deposits associated with these failure events.
