Mia Van Steenwinkel

Senior Petroleum Geologist

20+ years experience in E&P, training & coaching. Areas of expertise are: carbonates, play-and prospect evaluation, reservoir characterization, static modeling & field development planning in all phases of field life cycle - including EOR projects, sequence stratigraphy, sedimentology, design of workshops & training.

Bert Dijksman

Exploration Geologist

Bert is an experienced exploration geologist specializing in regional geological evaluation, hydrocarbon play definition, and value assessment based on all available data. His expertise includes the preparation of well proposals, Competent Person Reports, and field development plans. Bert has worked across a wide range of hydrocarbon basins worldwide, including Nigeria, the North Sea (UK and Dutch sectors), Uzbekistan, Oman, Myanmar, the Guyana Basin (Suriname), East Greenland, Bulgaria, Morocco, Guinea-Bissau, Tunisia, and Egypt.

Arie Speksnijder

Exploration Geologist

Experienced in regional geological evaluation and Hydrocarbon Play definition. Before the oil industry, Arie worked on study of European Alpine and Variscan orogenic belts. He evaluated basins and their prospective in the North Sea, onshore Europe, Atlantic Margins, Gulf of Mexico, Nigeria, Africa, Asia and Australia.

Senior Petroleum Engineers

Willem Schulte

IOR/EOR Specialist

Provides consultancy on field development planning, technology strategies and IOR/EOR methodologies. He focuses on understanding the physics and chemistry of the recovery mechanisms and from this understanding being able to select the best recovery process, given operating conditions, risks and life cycle opportunities.

Rik Drenth

Senior Reservoir Engineer

Conducted, supervised and coordinated many full field (re)development studies, mainly for Shell, but also for other companies. This included developing models, either analytical or simulation based, for the whole production stream from reservoir to pipeline, for oil and gas fields.

Jos Maas

Sr. Reservoir Engineer and SCAL Specialist

Over 40 years experience, mainly working for Shell. Focuses on research on SCAL techniques, with numerous peer-reviewed papers, and on teaching SCAL, EOR, geothermal. Interpretation-by-simulation of laboratory data has been the continuous factor in his career. Developed the SCAL simulator SCORES on jgmaas.com.

Senior Petrophysicists

Wim Looyestijn

Principal NMR Consultant

Researcher with 30+ years of experience, specialised in the interpretation of NMR core and log data. Experienced in other Petrophysics subjects, ranging from research into tool physics to development of new petrophysical applications: e.g. log deconvolution, thin bed analysis, core analysis, sponge coring, EOR trials.

Ap Van Der Graaf

Petrophysics Consultant

30+ years as a Petrophysicist. Has additional expertise in Integrated Reservoir Modelling ("IRM)" workflows (uncertainties in reservoir properties, Saturation Modelling and consistency between modelling scales). He is also highly skilled in Techlog having contributed to the development and the deployment in Shell.

Senior Production Chemists

Ron Hofland

Production Chemist Specialist

40 years of international experience. Became one of Shell’s global experts on reservoir souring and its mitigation, and is still active in this regard as principal consultant. Responsible for planning, conducting and interpreting of on-site coreflood experiments, geared to establishing quality specs for injected fluids by empirical means.
