    ENERGY COUNTRY REVIEW Sudan keyfactsenergy.com KEYFACTS Energy Country Review Sudan Most of Sudan's and South Sudan's proved reserves of oil and natural gas are located in the Muglad and Melut Basins, which extend into both countries. Natural gas associated with oil production is flared or reinjected into wells to improve oil output rates. Neither country currently produces or consumes dry natural gas. In Sudan, the Ministry of Finance and National Economy (MOFNE) regulates domestic refining operations and oil imports. The Sudanese Petroleum Corporation (SPC), an arm of the Ministry of Petroleum, is responsible for exploration, production, and distribution of crude oil and petroleum products in accordance with regulations set by the MOFNE. The SPC purchases crude oil at a subsidized cost from MOFNE and the China National Petroleum Corporation (CNPC). The Sudan National Petroleum Corporation (Sudapet) is the national oil company in Sudan.

  • Tectonic Inversion and Petroleum System Implications in the Rifts Of
    Tectonic Inversion and Petroleum System Implications in the Rifts of Central Africa Marian Jenner Warren Jenner GeoConsulting, Suite 208, 1235 17th Ave SW, Calgary, Alberta, Canada, T2T 0C2 [email protected] Summary The rift system of western and central Africa (Fig. 1) provides an opportunity to explore a spectrum of relationships between initial tectonic extension and later compressional inversion. Several seismic interpretation examples provide excellent illustrations of the use of basic geometric principles to distinguish even slight inversion from original extensional “rollover” anticlines. Other examples illustrate how geometries traditionally interpreted as positive “flower” structures in areas of known transpression/ strike slip are revealed as inversion structures when examined critically. The examples also highlight the degree of compressional inversion as a function in part of the orientation of compressional stress with respect to original rift structures. Finally, much of the rift system contains recent or current hydrocarbon exploration and production, providing insights into the implications of inversion for hydrocarbon risk and prospectivity.

    IOSR Journal of Applied Geology and Geophysics (IOSR-JAGG) e-ISSN: 2321–0990, p-ISSN: 2321–0982.Volume 5, Issue 5 Ver. I (Sep. – Oct. 2017), PP 19-25 www.iosrjournals.org Geology of the Muglad Rift Basin of Interior Sudan Hassan A. Ahmed and Maduka Bertram Ozumba Pan African University (PAU) Life and Earth Sciences Institute University of Ibadan, Nigeria Abstract: The Muglad rift basin of interior Sudan is an integral part of the West and Central African Rift System (WCARS). It has undergone a polyphase development which has resulted in three major phases of extension with intervening periods when uplift and erosion or non-deposition have taken place. The depositional environment is nonmarine ranging from fluvial to lacustrine. The basin has probably undergone periods of transtensional deformation indicated by the rhomb fault geometry. Changes in plate motions have been recorded in great detail by the stratigraphy and fault geometries within the basin and the contiguous basins. The rift basin has commercial reserve of petroleum, with both Cretaceous and Tertiary petroleum systems active. The major exploration risk is the lateral seal and locally the effect of the tectonic rejuvenation as well as tectonic inversion. In some oilfields, the volcanic rocks constitute a major challenge to seismic imaging and interpretation. --------------------------------------------------------------------------------------------------------------------------------------- Date of Submission: 23-09-2017 Date of acceptance: 06-10-2017 --------------------------------------------------------------------------------------------------------------------------------------- I.

  • Hydrocarbon Resource Potential of the Bornu Basin Northeastern Nigerian
    GLOBAL JOURNAL OF GEOLOGICAL SCIENCES VOL, 10, NO.1, 2012 71-84 71 COPYRIGHT© BACHUDO SCIENCE CO. LTD PRINTED IN NIGERIA. ISSN 1596-6798 www.globaljournalseries.com, Email: [email protected] HYDROCARBON RESOURCE POTENTIAL OF THE BORNU BASIN NORTHEASTERN NIGERIAN H. HAMZA AND I. HAMIDU (Received 18 February 2011; Revision Accepted 21 September 2011) ABSTRACT The separation of Africa from South America was accompanied by rifting and sinistral strike-slip movements that formed the Bornu Basin. The Bornu Basin form part of the West African Rift System. Geochemical analyse of samples from the Fika Shale shows that eighty percent of the samples have TOC values >0.5 wt%. Plots on the modified Van Krevelen diagram indicate organic matter that is predominantly Type III kerogen. A corresponding plot on the HI–Tmax diagram indicates an entirely gas generative potential for the source rocks. In the Bornu Basin which belongs to the West African Rift Subsystem (WARS) two potential petroleum systems are suggested. “Lower Cretaceous Petroleum System” – is the phase 1 synrift sediments made up of sandstones with an extensive system of lacustrine deposits developed during Barremian to Albian time. “Upper Cretaceous Petroleum System” – is the phase II rift sediments in the Bornu Basin which comprise mainly shallow marine to paralic shales, deltaic to tidal flat sandstones and minor carbonates. TOC values range generally from 0.23 wt. % to 1.13 wt. % with an average of 0.74 wt. % for the Fika Shale. KEY WORDS: Bornu Basin; Fika Shale; Source rocks; Organic matter; Petroleum System. INTRODUCTION the Chad Basin (Figure 1). It is contiguous with the N–S Exploration started in the Bornu Basin in the aligned part of the upper Benue Trough called the Gajigana area northeast of Maiduguri in 1979, when Gongola Arm or Gongola Basin.

ABSTRACT A review on the geology and petroleum potentials of the Nigerian Benue Trough and Anambra Basin is done to identify potential petroleum systems in the basins. The tectonic, stratigraphic and organic geochemical evalua- tions of these basins suggest the similarity with the contiguous basins of Chad and Niger Republics and Sudan, where commercial oil discovery have been made. At least two potential petroleum systems may be presented in the basins: the Lower Cretaceous petroleum system likely capable of both oil and gas generation and the Upper Cretaceous petroleum system that could be mainly gas-generating. These systems are closely correlative in tem- poral disposition, structures, source and reservoir rocks and perhaps generation mechanism to what obtains in the Muglad Basin of Sudan and Termit Basin of Niger and Chad Republics.
