Darvaza (Door to Hell): put out and launch gas production!In the past January, Gurbanguly Berdimuhamedow, the President of Turkmenistan, ordered to shut off the “Door to Hell”, the gas crater that has been burning for the past 50 years. According to Turkmenbashi, the crater, which has become one of the country's attractions, contaminates the ecology and is injurious to the citizens’ health. The world leading geological institutes and experts could not offer a solution other than undermining the crater. At the same time, they do not vouch for a favorable result of such an operation, as even more serious environmental problems can emerge in the future. However, do not despair, because there is a solution. Out company’s specialists developed a technical proposal that can not only extinguish the fire in a rapid and efficient manner, but also start up the gas field development. It has been suggested to recover gas from the unit and create an artificial underground dome, using the new technology and equipment, by creating a radius pattern of wells around the crater. The residual gas in the area of the formation (reservoir) unsealing will be released to the surface as a residual combustion, and this process will be terminated when the gas yield is over. Upon work completion, the running wells can be put into operation as the gas producing ones in compliance with all the relevant production parameters in natural drainage mode. The crater can be reclaimed depending on the project plan (concrete dome, artificial lake, etc.).
Water sustains life!Unavailability of water resources in many world regions, where water is lacking in the form of flows in the surface soils, underground rivers and lakes, is a global problem whose solving can ensure existence and economic growth of such regions. It is known that water can be found almost everywhere in formation conditions at different depths, but lack of technologies that would be capable to collect and raise water to the surface precludes the use of this resource. Our specialists have studied and analyzed a large number of different technical materials, including the information obtained during geological exploration, over many years of works related to use of special acoustic equipment at oil and gas fields. The general analysis has revealed one feature that is common for all the geological and physical investigations, as well as geological exploration, carried out in different world regions: regardless of the nature, conditions and amounts of the gas and oil-bearing fields bedding (the main investigation subject during the exploration and production), significant number of water-saturated formations (reservoirs) was found everywhere in all the studied areas. They were found even in those locations where oil content was insignificant or entirely unavailable. In general, such reservoirs can be characterized as water-saturated formations (reservoirs) of different types and forms, with bedding depth reaching 3000 m. In such areas the water is contained in the rock matrix pores like oil. The geological and physical survey of an oil and gas field Elements shown on the geological survey map are marked in white, black, red and yellow and are related to different characteristics of oil and gas content in-place. Geological reserves of water are marked in blue and light blue!!! The problem related to such reserves development consists in the lack of process solutions capable of displacing the water from the pore space and ensuring its draining to a collection point, such as a vertical producing well, in the relevant amounts. If it is possible to use water as an agent that allows maintaining the formation pressure and ensuring oil displacement to the producing wells drain during oil production from the mentioned geological structures, then pumping water into the formation, if the water production is needed under the same conditions, becomes simply meaningless. Acoustic wave impact can ensure efficient water displacement from the pore space and its motion to the collection point (hole toe of producing well). Such an impact can be used during development of water-saturated formations (reservoirs) with the same result as during oil production. It therefore becomes possible to arrange water production for potable and industrial purposes in regions that are in desperate need of this resource, which will also boost the economic growth through development of agriculture, industrial production and other types of human activities. Our company has already begun to develop the plan of such project implementation in the African continent. May 15, 2022
UGS (underground gas storage facilities): both gas and oil!Constructing a network of underground gas storage facilities (UGS) is a strategic goal making part of the common problem of the energy security in general. Availability of UGS in the country's portfolio allows not only regulating seasonal fluctuations of gas consumption, but also having well protected gas reservoirs located near the main industrial facilities. Use of seasonal prices would make the UGS attractive for investments. Many operating UGS currently make part of the gas transportation system, the expenses on their construction and operation are simply included into the price of natural gas supplied to the consumers, which means that they are all publicly funded facilities. Depleted oil fields with extremely low oil recovery factor (up to 25%) that are non-profitable for further development (even with currently high oil prices) are the most attractive facilities for UGS creation. Creating UGS in such places allows not only solving the problem of reservation of significant gas amounts, but also obtaining (during UGS operation in the mode of gas delivery to the gas transportation system) large amounts of oil, since here the gas is a working agent used to activate the oil reservoirs. It means that gas injection into the oil formation will not only compensate for the formation energy, lost during the operation, but also increase the oil mobility. Combining acoustic wave technology, owned by LandResources AS, to increase oil recovery of formations with active gas pumping can be the most rapid way and a commercially attractive variant to be used during the UGS operation. According to preliminary estimates, the oil recovery factor can be increased from 25% up to 50% (which means millions tons of oil) during UGS operation with use of the combined technology (gas injection and acoustic wave impact). At the same time, constructing and maintaining such a UGS is much cheaper than those of the above-ground facilities. So the publicly funded gas storage facilities not only become highly profitable and lucrative, but also turn into additional industrial sites of strategic importance. Our company has prepared a technical proposal for one of such facilities that is suitable for UGS construction therein and will allow extracting up to 10 million tons of oil by enhanced oil recovery method, using the wave impact technology.

Development of hard-to-recover fields of hydrocarbons.There are large proven oil reserves at the Canadian territory, Alberta province. According to the recent estimates, the reserves in bituminous sands of the province amount to 2.0 trillion barrels, with all the world oil reserves being equal to one trillion. Therefore great hopes are set on the Alberta oil reserves. It is planned to increase the oil production in these regions by five times by 2030. The Alberta oil has a feature. There are two oil types in the province that differ by the nature, age and bedding characteristics. The first one is the “conventional” oil, its age is about 350 million years. It is found at great depth of several kilometers in so-called oil traps in foothills of the Rocky Mountains and in the province central parts. The second oil is produced from bituminous sands, Tar Sand. Their age amounts to about 125 million years, the bedding depth is 50-500 m. The reserves are estimated at 1.6 trillion barrels in crude oil equivalent. Over 1.6 trillion barrels of oil per day are currently produced from Alberta oil sands. Overall area of oil sands region amounts to 140 million sq km. Though having a great resource potential, the oil production at these fields is not carried out in the required amounts. It is explained by the fact that technologies applied nowadays require great power input and large amounts of fresh water. According to some estimates, the power input is 2/3 of the total oil production costs, while others put the estimate at 1/5 of the oil energy potential. The scientists who study this issue believe it is a matter of the future. Now we can state with confidence that the “future” has come. The application of the new LandResources technology and equipment in these fields allows abandoning the use of significant amounts of energy and water, changing over the production mode to the dynamic (wave) one, ensuring thus highly efficient and highly profitable development of hard-to-recover hydrocarbon reserves with an increased oil recovery factor and low cost of the end product. Technical proposal on application of new technologies and equipment has been prepared by our specialists. May 4, 2022
Increased oil recovery – increased company value.As it is known, oil producer value consists of two main parameters: own funds and volume of the extracted hydrocarbons reserves. Increasing oil recovery factor is one of the main production tasks. The world average volume of extracted reserves is from 3% to 30% of the total share of proven reserves depending on the reservoir geological nature and field development method. It means that over half of the proven reserves remain in-place upon production completion. The main process problem related to such a low indicator of the final production is the imperfection of the process itself. The main oil production technology (flooding) that is widely used today was launched in the oil industry over 70 years ago, when the knowledge, equipment, machinery and other special equipment were at the last mid century level. Some of the basic flooding characteristics, affecting the oil recovery factor, are as follows: • inability of the agent (water) to cover all the reservoir volume, i.e. ensure oil displacement from the whole reservoir volume; • physical properties of water, fluid (oil) and rock matrix, i.e. difference between oil and water density, permeability and the formation (reservoir) heterogeneity, etc. As for the hydrophobic formations (reservoirs) and a number of fields with highly viscous oil reserves, the flooding technology cannot be applied in this case or its use is simply senseless (not profitable). When new technology and equipment are used, i.e. when system of oil and gas displacement through wave impact on the reservoirs is created, it becomes possible to cover the whole formation volume. Physical characteristics of the acoustic flow in the created wave field, allow creating a constant pressure distribution in the reservoir at the speed of sound (depression-repression) from the injection well to the producing one, thus ensuring displacement of liquid phases (oil, gas) in the volume up to 90% of the initial proven reserves. In this case, the geological and physical parameters of the rock matrix and oil properties are irrelevant; the entire reservoir, which becomes a waveguide, is put into operation. The foregoing means that applying new technology and equipment makes it possible to increase oil recovery and hence the capitalization (value) of the oil producer in line with its own resources increase.
