Welcome to the Global Hotspots Series | Africa

EAGE GLOBAL HOTSPOTS: ALGERIA

2 February 2021 | Online

10.00 AM-4.30 PM GMT+1

Event Overview 

Algeria is the largest country in both Africa and the Arab world with a total landmass of 919,600 square miles. Rich in natural resources, Algeria has the tenth-largest proven reserves of natural gas in the world, is the sixth-largest gas exporter and has the third largest reserves of shale gas.

Along with gas, Algeria is a large oil producer with 12.2 billion barrels of proven oil reserves. The country exports 540,000 b/d of its total production of about 1.1 million b/d. All proven oil reserves are held onshore, though offshore exploration is in the early stages. With most of Algerian hydrocarbons derived from mature and depleting fields, and in line with its ambition to boost output, an important focus is being placed on the need to optimize production, notably through enhanced recovery technology. 

About two-thirds of Algerian territory remains unexplored or largely underexplored. Most of these areas are in the north, the deep south and offshore. (Source: International Trade Administration)

PRESENTATION TITLE | Exploration Challenges & Potentiality in Algerian Basins

So far, the Petroleum exploration in Algeria has been mainly devoted to prospecting structural taps. The large gap is observed between the quantities of hydrocarbons discovered and the quantities generated and expelled. The main question to ask, where are these quantities of Hydrocarbon? We believe that subtle traps, unconventional reservoirs and frontiers basins can harbor huge amounts of hydrocarbons. In recent years we have tested some these opportunities, explored some frontiers basins, acquired new data and carried out a lot of studies. During this presentation we will share with you the results obtained, and review some all of those opportunities by illustrating some of them with examples.

PRESENTATION TITLE | Utilizing the wave equation for effective de-risking of hydrocarbon exploration

Hydrocarbon exploration and exploitation relies on seismic data to fill in the lack of information between wells. AVO [Amplitude Vs Offset] seismic inversion has emerged as a tool to extract quantitative elastic properties about the reservoir. Based on this technology, operators can predict, in some cases, the presence of hydrocarbons as well as the reservoir properties. However, AVO inversion is based on a series of assumptions and linearizations of the wave propagation. The Wave-Equation-based inversion is a natural next step in the evolution of seismic inversion techniques, adopting a non-linear, full wavefield approach. This type of inversion is now possible due to advances in the computational front. In this talk, we will be analyzing the theory behind this non-linear solver along with some key applications that have led to de-risking of a various relevant hydrocarbon exploration projects.

This presentation will talk about areas of interest (ZOI), revealed by several integrated regional studies launched by ALNAFT over the past three years for the assessment of the hydrocarbon potential in place within the main basins of the Algerian hydrocarbon mining domain, even Offshore and Onshore domain, which may interest oil and gas companies (IOC) to invest in the exploration for the hydrocarbon potential in place, still under-explored.


Giancarlo Cristofalo

Fugro ITALY SpA

Giancarlo is the Marketing and Commercial Manager at Fugro ITALY SpA. His specialties include: Geophysical Marine Survey, Land geophysical and geological survey and offshore marine survey in general.

PRESENTATION TITLE | Gas seep/Geochem/Heat Flow and Shallow 2DHR Seismic Surveys for Hydrocarbon Exploration

A detailed interpretative model of the hydrocarbon seepage is useful to reduce offshore exploration risk and cost. The link between hydrocarbon seeps and commercial reserves is well established. Marine seep hunting is at the forefront of hydrocarbon exploration due to recent advances in offshore geophysical and geochemical technologies. Fugro’s team of geoscientists deliver an advanced client-focused seep hunting service for the offshore industry creating a competitive advantage for our clients. This Case of Study creates a programme consisting of a legacy data study, geophysical acquisition survey, targeted coring, geochemical sampling and heat flow measurement program. It demonstrates how Fugro approach, compared to historic industry success rates, can more than double the likelihood of recovering samples bearing evidence of migrated liquid petroleum and thermogenic gas. Identifying and sampling sites where deep fluids have migrated to the seabed provides the highest quality geochemical data for understanding the deep reservoir.

PRESENTATION TITLE | Characterization, distribution and prospectivity of Paleozoic shale plays across Algerian Saharan Platform: a guide for regional sweet spots tracking

Following an extensive integrated subsurface study intended at the scale of the Algerian Saharan cratonic platform, the spatial distribution (thickness) and main characteristics (organic matter typing, mineralogy, Corg richness, petrophysical properties) of the distinctive Paleozoic source-rocks (e.g. Silurian and Frasnian source-rocks) have been precisely deciphered. The evaluation results for the Algerian shale plays are also compared with the main productive US shale plays analogs. 

The aim of this talk relies on the overview of the subsequent regional prospectivity of the shale-plays defined, regarding their tectono-stratigraphic framework, the different play typologies that occur, the main rock-types in presence. It aims at providing subsequent guidelines for regional sweet-spots definition and tracking.

PRESENTATION TITLE | High density seismic finally accessible to all industries

High density seismic has been synonym of high quality subsurface images and attributes for more than 2 decades now, and although firstly made available by innovative source technologies like blended acquisition, which converted vibroseis fleet into very efficient autonomous single sources points, the receiver side was lagging behind with bulky heavy cables, and later, bulky heavy nodes, preventing it from spreading the sensors efficiently and reaching the full potential of an unlimited channel count system. So more nimble receiver systems were required to respond to the continuous need for better seismic images at a lower cost, lower environmental impact, and lower HSE exposure for both Oil&Gas and non Oil&Gas industries. In this paper, we will introduce the story behind the invention of a new generation of nimble nodes and how it has already disrupted the way seismic is being acquired, especially in difficult terrains, making high density seismic finally accessible to all industries.

PRESENTATION TITLE | Hydrocarbon potential in the Eastern Atlas Range with emphasis of Cretaceous plays, Algeria

The Saharan platform of Algeria covers almost two thirds of the country and holds most of the hydrocarbon resources, whereas northern part of the Algeria is under-explored with limited success. Northern Algeria, a province shaped to its current state largely by Alpine deformation, encompassing Tellian atlas and Saharan atlas. Few discoveries in SEC (south east Constantine) and one in Hodna (Oued Gueterini) proved the presence of a working petroleum system in these northern basins. Most of the discovery so far are made in SEC where primary source rock is Lower Turonian/Upper Cenomanian (Luning et al, 2004, Groshney et al, 2013; Bora et al, 2019) whereas other source rock potentials remains relatively less known.

ALNAFT in association with Schlumberger (D&I) launched a regional study in 2018 aimed at hydrocarbon potential assessment of this region.  It was the first attempt to integrate regional scale analysis from Hodna, Saharan Atlas, NEC (NE Constantine) and SEC (SE Constantine). The study is based upon regional synthesis of stratigraphy and structural interpretation consistent with outcrop data, well data including core, geochemical data, and huge volume of legacy (report) data transformed into digital format in Petrel. Regional mapping of potential source and reservoir rock intervals, many 1D petroleum system models, followed by seven 2D petroleum system models along structurally restored sections covering the complete area helped to assess play potential in this region. 

The study area extends over 240,000 km2. Over 35,000 LKM 2D Seismic, 1800 Km2 3D seismic, 270 wells, data from huge legacy data base (reports) transformed into digital format in Petrel. More than 10000m of core inventoried, of which ~2000m most representative core interpreted covering full stratigraphy across the basin. Over 103 wells with variable quality geochemical data reviewed and used for source rock analysis.

Despite data quality a primary challenge in this area, lithostratigraphically consistent and coherent digital data base across Hodna, Saharan Atlas, SEC and NEC achieved. Integration of sub-surface and surface data (surface/outcrop geology map), G&G data integration from Jurassic to Miocene and corresponding regional maping including potential source and reservoir rock intervals helped to understand play fairways across the basin and identify potential leads. 

In an ongoing second phase of this study, detailed sequence stratigraphy-based play fairway mapping with emphasis on Cretaceous sequences is ongoing which will be followed by play chance mapping and undiscovered play & prospect resource assessment. Lithostratigraphically, two play levels were mapped in this area corresponding to Cenomanian-Turonian transition and top Albian whereas sequence stratigraphy-based play analysis helped to map two additional plays. 

Thousands of man hours invested from Schlumberger global expertise to analyze and synthesize results including Cambridge Carbonate as key collaborator.
