This seminar covers the fundamental principles concerning how hydraulic fracturing treatments can be used to stimulate oil and gas wells. It includes discussions on how to select wells for stimulation, what controls fracture propagation, fracture width, etc., how to develop data sets, and how to calculate fracture dimensions. The seminar also covers information concerning fracturing fluids, propping agents, and how to design and pump successful fracturing treatments. As the industry wrestles with another price cycle, making sense of the world in which the oil and gas industry will operate is important to understanding the actions (by engineers, corporations, and governments) which must be taken today so that the oil and gas industry may prosper in the future. Hydraulic fracturing has been touted as a ‘new technology’ (though a misnomer) which is opening access to un-tapped value (in the USA) and lowering the cost of energy across the globe by shifting the balance between supply and demand.
The Apollonia tight-gas chalk play is located in the Abu Gharadig Basin in the Western Desert of Egypt. This has long been ignored as a gas play in the overburden, while the Jurassic and Cretaceous oil fields deeper in the basin have been explored and developed. Large areas of the North Sea contain Cretaceous sediments, which form a massive hard layer of chalk that historically has presented a major drilling risk and expense to operators in the area.
As the fallout deepens from the coronavirus pandemic and the global collapse in oil and gas prices, oil- and gas-producing regions around the world are feeling the pain. Landmark deal called most significant since 1979 peace treaty. The Arab world’s most populous country has awarded a string of concessions in a bid to become the region’s next major supplier of natural gas. The Sidri 36 appraisal well confirmed the downdip westward extension of the Sidri 23 discovery announced last July by the Italian major. Conventional oil and gas discovered resources in 2019 are on pace to rise 30% from last year and reach their highest level since the beginning of the industry downturn.
Multistage horizontal well designs were first implemented in the Bakken in 2007. Since then, more than 12,000 wells have been completed in either the Middle Bakken or Three Forks zones. The Apollonia tight-gas chalk play is located in the Abu Gharadig Basin in the Western Desert of Egypt. This has long been ignored as a gas play in the overburden, while the Jurassic and Cretaceous oil fields deeper in the basin have been explored and developed. Dubai Petroleum embarked on a new mission last year to drill and complete its first multistage, hydraulically fractured, and propped horizontal well from an offshore platform.
New report offers guidelines for pressure pumpers of the future. A 3-year study of air quality, soils, groundwater, and waterways found few to no effects as a result of hydraulic fracturing operations in Surat Basin coal seam formations. Not everybody suffers when US oil producers slash production. Among the beneficiaries could be US gas producers who will benefit because less oil production will mean a lot less gas on the US market. A downhole compressor solution based on advanced magnetic technologies completed its first field trials in an unconventional gas well.
The merged companies will offer large-diameter coiled-tubing, directional drilling, snubbing, wireline services, and pressure pumping services. The amount of uncertainty related to directional drilling makes accurate drilling challenging, leaving much to human know-how and interpretation. Additionally, few path-planning methods in the literature consider the directional steering tool being used. This paper describes the analysis of sidetracks drilled in an open hole by an annular ledge formation method with a downhole motor in multilateral wells. Although multilateral and long-reach wells are common, the technological development is not complete.
Africa (Sub-Sahara) Sonangol's deepwater Orca-1 well encountered oil in the presalt layer of Block 20/11 in the Cuanza basin offshore Angola. The well reached a measured depth of 12,703 ft. Initial well tests saw flow rates of 16.3 MMcm/D of gas and 3,700 BOPD. Cobalt International Energy (40%) is the operator, with partners Sonangol Research and Production (30%) and BP Exploration Angola (30%). Asia Pacific Premier Oil's Kuda Laut-1 well in Indonesia's Tuna production sharing contract has encountered 183 net ft of oil-bearing reservoir and 327 net ft of gas-bearing reservoir. Following evaluation operations, the well will be sidetracked to drill the Singa Laut prospect in an adjacent fault block. Premier is the operator (65%), with partner Mitsui Oil Exploration Company (35%).
Africa (Sub-Sahara) Eni Congo discovered oil at its Minsala Marine 1 well offshore the Republic of the Congo in Marine XII Block 12 km from the operator's recent Nené Marine discovery. Minsala intersected 420 m of gross pay and encountered light oil in a Lower Cretaceous presalt sequence. The well reached a total depth of 3700 m. Eni (65%) is operator, with state-owned partner SNPC 25%), and New Age (African Global Energy) Limited (10%). SOCO EPC's Lindongo X Marine 101 Well (LXM-101)--located offshore the Republic of Congo in Marine XI Block--encountered oil in a clastic sequence of the Djeno sands, with early log interpretation indicating approximately 50 m of gross pay.
Asia Pacific Strike Energy and Warrego Energy discovered gas in the multireservoir West Erregulla-2 appraisal well in the onshore North Perth basin of Western Australia. Strike, as operator, said the well encountered a gross gas column at least 97 m thick in the Kingia formation. Strike and Warrego are 50–50 joint venture partners. Latin America-Caribbean Gran Tierra Energy produced oil from new pay in the Acordionero field in Colombia. The Acordionero-48 well produced at an average rate of 509 B/D from Paleocene-Eocene Lisama E, located just below the main Lisama A and C reservoirs, during 115 producing hours. Gran Tierra holds 100% working interest in the field. Tullow Guyana encountered 55 m of net oil pay on its Jethro-1 well, drilled to 4400 m TD in 1350 m of water in the Orinduik block offshore Guyana, and says the prospect could hold more than 100 million bbl of recoverable oil.
PETRONAS FLNG SATU (PFLNG1) is a floating liquefied natural gas facility producing 1.2 million tonnes per annum (mtpa) of LNG, on a facility that is 365m long, and 60m wide, making it among the largest offshore facility ever built. The PFLNG1 project is the first of its kind in the world and is the first deployment of PETRONASâ€™ Floating Liquefied Natural Gas (FLNG) technology, consolidating the traditional offshore to onshore LNG infrastructure into a single facility. This will see a giant floating facility capable of extracting, liquefying and storing LNG at sea, before it is exported to customers around the globe. The FLNG journey has come a long way since 2006, with many technological options explored to monetise and unlock the potential of small and stranded gas fields. Moving an LNG production to an offshore setting poses a demanding set of challenges â€“ as every element of a conventional LNG facility needs to fit into an area roughly one quarter the size in the open seas whilst maintaining safety and increased flexibility to LNG production and delivery.
