Energy company based in Madrid is seeking talented professionals to join our dynamic team and fill the following position, contributing to innovative projects across Spain and North Africa. Senior Petrophysicist / Madrid --------------

MIDAD Energy

is seeking a

Senior Petrophysicist

based in

Madrid

to lead

petrophysical evaluation and interpretation

for our

North Africa projects

(Algeria, etc.). This role focuses on

advanced petrophysical analysis, rock typing, saturation-height modeling (Sw), and reservoir characterization

to support field development and production optimization. The ideal candidate will have

extensive experience in North African basins

, a strong background in

integrating well log, core, and seismic data

, and the ability to collaborate with

reservoir modeling and engineering teams

to drive data-driven decisions.

com] with the subject: “Senior Petrophysicist – Madrid ” . Perform

detailed petrophysical evaluations

using

open-hole and cased-hole logs, core data, and special core analysis (SCAL) . Conduct

uncertainty analysis and sensitivity studies

to assess petrophysical variability and risk. Rock Typing & Facies Analysis Lead

rock typing studies

to classify reservoir intervals based on

lithology, pore geometry, and flow units

. Integrate

core descriptions, thin sections, and log data

to define

electrofacies and hydraulic flow units (HFUs) . Collaborate with

geologists and reservoir engineers

to ensure consistency between petrophysical rock types and dynamic reservoir behavior. Develop

saturation-height functions (capillary pressure models) using

core data, well logs, and production data

. Calibrate

Sw models

with

production logs, well tests, and dynamic reservoir data

. Work closely with the

Reservoir Characterization and Modeling team

to integrate petrophysical data into

static and dynamic reservoir models

. Provide

petrophysical inputs

for 3D geological and simulation models

, ensuring consistency with well data and geological concepts. Well Log Quality Control & Data Integration Conduct

rigorous QC of well log data

(gamma ray, resistivity, density, neutron, NMR, etc.) Ensure

data consistency

between petrophysics, geology, and reservoir engineering disciplines. NMR interpretation

for pore-size distribution and fluid typing. Dielectric and spectral gamma ray analysis

for complex lithologies. Fracture and stress analysis

using image logs (FMI, UBI). Work with

geologists, geophysicists, and reservoir engineers

to ensure petrophysical interpretations align with

geological models and dynamic reservoir behavior

. Participate in

integrated reservoir studies

and

field reviews

for North Africa projects. Mentor

junior petrophysicists

and provide

technical guidance

to cross-functional teams. Master’s or PhD in Petrophysics, Petroleum Engineering, or Geophysics

. Proven experience in rock typing, Sw modeling, and reservoir characterization

. ~ Petrophysical software
