Gas to Geothermal, maximizing value for both 'Gas' and 'Green' in Vermilion's onshore Middenmeer field.
By Michiel Ottevanger (Vermillion)

Abstract:
The end of gas field life, high geological risk exploration targets and a call for the renewable energy transition. What will be the role of the onshore E&P industry in the future Dutch Energy mix and how can Vermilion play a leading role in the transition to a lower carbon dioxide economy? The Dutch government had a Natural Gas revenue of EUR2.4 billion in 2016, a decline of 85% compared to 2013 and the lowest since 1975. On the other hand the governmental investments in the renewable energy transition should be around 200 billion euros, according to 90 Dutch professors. Dutch natural gas, and its related revenues, could be the transition fuel towards a renewable energy future. Innovative ideas, using existing infrastructure and joining forces between E&P industry and the Renewable Energy industry could lead to effective and efficient production of both natural gas and renewable energy. Vermilion is exploring its role in the energy transition, while remaining a healthy E&P business. One of its projects is in the province of North-Holland, where the onshore Middenmeer gas field reached its end of field life. Only 5 kilometers further East, one of the largest greenhouse areas of Europe is being developed, with a demand for heat. A perfect chance to give the Middenmeer wells a second life to provide the greenhouses with geothermal energy and maximize the recovery factor of the Middenmeer field.

Gas meets Wind, and how to repurpose the oil and gas infrastructure to create a stable and reliable Northsea Powerhouse
By Rene Peters (TNO)

Abstract:
Oil and Gas production from the Dutch offshore sector is rapidly declining under current market conditions and political environment. Independently, offshore wind is rapidly developed to realize the Dutch growth ambitions on sustainable energy until 2023. While gas has been a reliable, affordable and stable source of energy, income and employment for the Netherlands for decades, renewable sources bring along many challenges related to grid stability, capital costs and public investments. Instead of considering these two developments as independent and not connected, there can be a large benefit of considering North Sea Energy as an integrated system, where existing infrastructure can be repurposed for energy transport, conversion and storage, and offshore wind development can be accelerated more cost efficiently. Can the lifetime of existing oil and gas assets be extended while accelerating the transition to an emission free energy production from the North Sea?

Monthly Lecture: Marten ter Borgh (EBN). The Hydrocarbon Potential of the Lower Carboniferous in the Northern Dutch Offshore

Lecturer: Marten ter Borgh

18:00 - 19:00: Lecture

Production of hydrocarbons from Carboniferous reservoirs in the Southern North Sea and adjacent areas comes primarily from the Upper Carboniferous (Westphalian). The discovery and development of gas fields with Lower Carboniferous reservoirs such as the Visean Breagh field and the Namurian Pegasus field triggered new interest in the hydrocarbon potential of the Lower Carboniferous in the Southern North Sea and Mid North Sea High area. EBN therefore evaluated the potential of this stratigraphic interval in the northern Dutch offshore.

The abundance and thickness of reservoir-quality Visean sands was found to increase from Breagh towards the northeast and significant amounts of Namurian sands are expected. A structural framework was developed for the area to identify closures, understand source rock and reservoir distribution, source rock maturation and trap formation. Multiple undrilled structures were identified. Visean-Namurian coals and shales are considered promising source rocks to charge these structures in A, B and northern E blocks. The presence of a mature Palaeozoic source rock in the Step Graben and Dutch Central Graben is supported by hydrocarbon shows and vitrinite reflectance data. In the southern E and F blocks charge may also occur laterally from Upper Carboniferous Westphalian coals.

A regional post-well analysis showed that the Lower Carboniferous is virtually untested in the Dutch northern offshore. Two tests were positive but had high N2 contents, one was negative, while ten wells were drilled off-structure and are therefore considered invalid tests of this play.

We conclude that the Lower Carboniferous in the northern Dutch offshore has significant hydrocarbon potential.

Monthly Lecture: Rutger Gras (ONE) and Richard Neale (Cegal). Fault Seal in the Upper Slochteren (Rotliegend), Case Study from the Gillian Gas Field, Block L11c, Netherlands Offshore

Lecturer: Rutger Gras

17:00 - 18:00: Social Drinks
18:00 - 19:00: Lecture

Authors: R. Gras (ONE), R. Neale (Cegal), O.J. Rossebo (Cegal) and E. Verkuil (ONE).

In 2015 Oranje-Nassau Energie (ONE), operator of the Gillian Unit joint venture, drilled the L11-14 exploration well targetting the Gillian prospect. This well found the Permian-aged Rotliegend reservoir sands (the Upper Slochteren) gas bearing with virgin pressure. The Gillian gas field is a downthrown fault-closed tilted fault block, vertically sealed by Zechstein evaporites, in a location adjacent to the depleted L11b-A gas field. Pre-drill the critical risk for the Gillian prospect was the fault seal required to effectively trap gas in the Upper Slochteren sands. The present paper focusses on the pre-drill evaluation of the Gillian gas field, with a particular emphasis on the seismic reservoir characterisation using AVO-stacks and rock physics models, structural modelling and fault seal analysis. This case study demonstrates how a Rotliegend downthrown fault closure was derisked by a combination of conventional seismic interpretation complemented by seismic reservoir characterisation and structural modelling.

Monthly Lecture: Process Safety in drilling wells – the importance of subsurface standards

Lecturer: Mieke Kosters

17:00 - 18:00: Social Drinks

18:00 - 19:00 Lecture: Process Safety in drilling wells - the importance of subsurface standards

Mieke Kosters (Shell)

From deepwater blowout prevention to fraccing, the focus on subsurface safety aspects of our industry remains at an all-time high. When it comes to designing wells and projects, subsurface data and its interpretation provide a key building block to safety. Getting it wrong can have major safety, environmental, economic and reputational implications.

In 2013 Shell introduced eleven global subsurface standards to achieve a reduction in HSE exposure by standardizing subsurface requirements. High level industry incidents high light the importance of especially high quality pore pressure/fracture gradient prediction, formation top prediction, and geohazard assessment. Examples of key requirements will be discussed.

Abstract:
Traditional models of passive margin evolution, suggesting generalised regional subsidence with rates decreasing after the break-up, have been questioned in the last decade by a number of detailed studies. The occurrence of episodic km-scale exhumation well within the post-rift stage, possibly associated with significant erosion, have been documented along the Atlantic continental margins. Offshore Morocco, numerous wells located on the shelf encounter a nearly complete syn- and post-rift succession. The offshore basins have potential petroleum systems, however, to date hydrocarbon exploration has mostly been unsuccessful, with a critical risk being the location of significant sandstone reservoirs. A key is to constrain when, where, and with what amplitude the unloading events occurred in the hinterland to quantify potential volumes of eroded sediments. Despite the wide-spread and increasing body of evidence supporting post-rift exhumation, there is still limited understanding of the mechanism or scale of these phenomena. Most of these enigmatic vertical movements have been discovered using low-temperature geochronology and time-temperature modelling along strike of passive margins. These observations call for an integrated analysis of the entire source-to-sink systems as a pre-requisite for a full understanding of the involved tectonics.

To better define the source-to-sink systems, we reconstructed the geological evolution of a 600km long transect across the Anti-Atlas belt of Morocco (ENE–WSW), from the offshore passive margin basin to the interior of the African plate. Extending the presently available low-temperature geochronology database and using a new stratigraphic control of the Mesozoic sediments, we present a reconstruction of vertical movements in the area. The results based on sampled rocks indicate exhumation by circa 6-10km after the Variscan orogeny until the Middle Jurassic. During the Late Jurassic to Early Cretaceous the region was subsequently buried by 1-3km, and later exhumed by 1-3.5km from late Early/Late Cretaceous onwards. From the Permian to present day, the Western Anti-Atlas is the link between the generally exhuming Anti Atlas and continually subsiding offshore basins.

To quantify the source-to-sink systems, we digitized available time-temperature modelling results and associated them with dynamic geotherms for temperature-to-depth conversion. This allows calculation of denudation rates, presented in a series of contour maps. Self-similar models are grouped into three distinct regions, distinguished by discontinuous timing and magnitude: the Meseta, Anti-Atlas and Reguibat Shield. The presently outcropping Variscan rocks in the Meseta were close to the surface during the Permian/Late Triassic, followed by subsidence until the Late Jurassic, exhumation in the Late Jurassic/Early Cretaceous, renewed subsidence during the Late Cretaceous and a finally exhumation in the Cenozoic. The sampled Reguibat Shield basement rocks are marked by subsidence from the Permian to Triassic, and exhumation from Jurassic onwards for most of the old massif. Resulting denudation rates range from 0.21 to -0.01km/Ma. The highest denudation rates compare with values typical of rift flank, domal or structural uplifts and are only obtained in the Anti-Atlas during the Early to Middle Jurassic and in the High Atlas in the Neogene. The mean value of 0.04km/Ma compares with weathering/peneplain rates. Estimates of eroded volumes from Permian onwards are 2x106, 0.6x106, and 0.2x106 km3 in the Reguibat Shield, Anti-Atlas and Meseta respectively.

The results provide valuable source-to-sink qualitative and quantitative maps for seven selected periods in Phanerozoic times.

Montly Lecture: Conventional and Deep Geothermal Energy Opportunities in Noord Brabant

Lecturer: Jos Terken

Abstract:

Read more...

My presentation will start with a short intro of ECHR, a think tank of a dozen, mostly retired engineers with life time careers in Philips, TNO, TUE, and TUD, several ex-business owners and one geologist. The aim of this energy club and city council is to turn Helmond and its surrounding villages into a climate-neutral region by the year 2035.

A major step forward in this process was the signing of Green Deal 201 in the spring of 2016 between the Dutch and Provincial governments, interested customer companies and 5 major cities in Noord Brabant. In this deal, efforts and experiences will be bundled, funding organized and 5 well doublets drilled to explore the potential for conventional and deep geothermal energy. Geothermal energy is as an alternative for heat from fossil fuel and, if we can make it economic, expected to become the main heat and steam provider for the industry, greenhouses, and housing. The target reservoirs are the Lower Triassic Buntsandstein (mostly heat) and Dinantian Kohlenkalk limestones (mostly steam).

Next I will discuss the structural setting and geological history of the Roer Graben, describe the geothermal reservoirs and visualize the graben in 3D using two videos screen-captured from a Petrel model. This model is in depth and contains all 2D/3D seismic, well tracks and log data from the NLOG site, depth surfaces made by TNO, information from literature loaded as GIF files pictures or draped across surfaces, predicted porosity and permeability properties, proposed producer - injector well tracks, and spatial data.

Finally, I want to mention an issue that could jeopardize or unnecessarily delay the development of this alternative energy source and enlarge its business risks. Most parties currently involved are ‘new kids on the block’, often small in size, with limited own capital and hardly any experience in drilling, developing, and operating geothermal systems. As a result underestimation of the preparation efforts, risk assessments, in-house experience/knowledge and financial means required developing this business is common. So far this poor man’s approach has not led to financial ruin of a client or dangerous situations, but that all is not well can be concluded from the fact that most realized geothermal systems fail to meet expectations both in water flow and exploitation efficiency. A surprise as nearly all these systems are located in data-rich areas, intensively explored for oil and gas in the past. It may be time for the government to get involved especially now moves are made into areas that are less well known and also more complicated by active faulting or due to pressure depletion caused by gas production. To permit a more rapid development and efficient exploitation of this climate-neutral energy source, resources, R&D and finances could be made available to ease exploration efforts and facilitate pro-active studies (e.g. to avoid scaling problems and poor well designs).
