“…Di Cekungan Banyumas, zeolit dapat ditemukan dalam jumlah yang cukup signifikan di daerah Cihonje. Menurut Seubert (2015) kapasitas adsorpsi zeolit dapat mencapai 30 % dari berat batuannya atau dengan kata lain 1 ton zeolit dapat menyerap gas mencapai 300 kg. Hal ini dapat menjadi tambahan bagi sumberdaya gas terutama gas metan.…”

Formasi Halang merupakan formasi yang dikenal dengan struktur turbidit dan diendapkan pada lingkungan laut dalam. Penelitian tentang reservoir Formasi Halang telah ditulis oleh beberapa penulis sebelumnya menyebutkan bahwa porositas batupasir Formasi Halang cukup baik namun diragukan permeabilitasnya, sehingga permasalahan utama reservoir batupasir Formasi Halang di Cekungan Banyumas adalah permeabilitasnya. Metode penelitian yang digunakan meliputi pengukuran penampang stratigrafi di lapangan, analisis dan interpretasi data laboratorium berupa data porositas, permeabilitas dan densitas, yang diintegrasikan dengan data sekunder hasil penelitian sebelumnya. Hasil penelitian menunjukkan bahwa fasies proksimal dan medial Formasi Halang mempunyai potensi sebagai reservoir dan adanya rejim tektonik kompresi pada umur Plio-Plistosen membentuk kekar-kekar pada batupasir sehingga menambah permeabilitasnya. Data sidewall core sumur Karang Gedang-1 juga menunjukkan masih adanya permeabilitas yang bagus pada batupasir Formasi Halang di bawah permukaan. Data XRMI juga menunjukkan adanya rekahan terbuka sebagian pada kedalaman sekitar 13.000 – 14.000 kaki di bawah permukaan, sehingga kesimpulannya batupasir turbidit Formasi Halang mempunyai potensi sebagai reservoir hidrokarbon di Cekungan Banyumas.Katakunci: Batupasir, Cekungan Banyumas, Formasi Halang, Reservoir.

“…In Indonesia, accumulations of hydrocarbons have been observed in volcaniclastic rocks, based on image profiles and calculations of total organic carbon (TOC), have allowed the development of new concepts of plays in oil systems (Seubert, 2015). In Vietnam, Tan et al (2016) applied processing techniques and seismic attributes to improve the imaging of fractured basements.…”

Within the oil and gas industry, igneous rocks are still seen as exploration and production challenges, due to their diverse petrogenesis and the wide range of values of some important petrophysical properties. This petrophysical variability depends on both primary and secondary processes. These facts made these rocks unattractive for decades. This condition is still observed in many fields around the world. This article has as main objective to make a historical review of studies developed globally with a focus on igneous rocks that act as a reservoir in petroleum systems. The review covered in this article was developed from a compilation of global data, thus allowing an overview of the countries that produce hydrocarbons in volcanic rocks, what types of rocks, geological age, and size of the reserve. Countries such as China and Indonesia stand out with higher daily production, exceeding orders of quantities of 108 cubic meters of gas and 104 tons of barrels of oil. In these countries, geological patterns are already being noticed in volcanic reservoirs, such as more recent geological ages and typical lithologies. Also, this work seeks to emphasize the importance of studying this type of reservoir, as its knowledge can lead to the solution of real problems within the world oil and gas industry.
