EXAMPLES
Example 1: Initial set-up for a depleted oil well.
Purchasing or leasing land having a depleted oilwell with a wellbore and a well casing already in place such that the wellbore and well casing extend into a subterranean formation that has been substantially depleted of hydrocarbons. Attaching a valve assembly to the head of the wellbore such that the valves of the valve assembly can control what enters and leaves the wellbore. A suitable valve assembly can be purchased from oil field service companies such as Mogas, Suez Water Technologies, and Halliburton, among others.
Using a bulldozer to dig a pool into the surface within about 100 to 200 meters out of the valve assembly of the depleted oil well. Digging the pool to a depth up about 5 feet any length and width of about 100 meters. The pool would be filled with water and alga of the genera Chlorella or Scenedesmus which can be purchased from UTEX Culture Collection of Algae at the University of Texas at Austin. A series of rods would be extended over the length and width of the pool to form a support structure, and a transparent polyethylene cover would be used to seal the top of the pool, making it substantially airtight. The covered pool would serve as an algal bioreactor.
A free-standing structure would be connected by one or more gas pipes to the algal reactor to form a hydrogen separation building. The hydrogen separation building would be connected to the subterranean formation either directly by drilling a wellbore into the subterranean formation or by one or more pipes connecting to the valve assembly. The freestanding structure would contain a T-junction connecting a gas path from the subterranean formation to a hydrogen selective membrane, where in on one side of the hydrogen selective membrane (the filtered hydrogen side) the hydrogen separator is connected to a hydrogen storage tank by a gas pipe. A suitable hydrogen selective membrane can be hollow microfiber membranes, which can be purchased from Generon located in California, among other suppliers. Alternatively, palladium-based membranes, such as those available from HySep, can be used for hydrogen separation. The other side of the membrane (the carbon dioxide side) would be connected to the algal bioreactor by a gas pipe.
The valve assembly would be connected to two containers, one serving as a microorganism container and one serving as a hydrogen production enhancer container. The valve assembly would further connect to a genetic material testing facility wherein the genetic material testing facility includes a DNA and/or RNA sequencer and would further connect the valve assembly to the DNA and/or RNA sequencer, such that sequencing could be controlled by a computer or remotely. A suitable DNA and/or RNA sequencer would include the Minion nanopore sequencer, which can be commercially purchased from Oxford Nanopore Technologies located in the United Kingdom.
The algal bioreactor would further be connected to the subterranean formation either directly by a well bore and liquid tube or indirectly by connecting the algal bioreactor to the valve assembly.
Example 2: Increasing hydrogen production from a subterranean formation having a low amount of hydrogen producing microorganisms.
Providing the set up according to Example 1 above, with the following changes.
Taking a gas sample of the hydrogen produced by the subterranean information and analyzing the amount of hydrogen in the gas sample using a gas chromatograph with PDHID (Pulse Discharge Helium Ionization Detection), which can be purchased from Custom Solutions Group which is located in Houston, TX. Determining that the hydrogen output is too low.
Taking a liquid sample from the subterranean formation. Performing a bulk DNA/RNA extraction by performing the steps detailed in the DNeasy PowerSoil Pro Kit from Qiagen (Hilden, Germany). Quantifying the amount of DNA/RNA using real-time PCR and primers that target the 165 rRNA gene. Sequencing the DNA/RNA from the samples using a commercially available kit such as the 16S sequencing kit, which is commercially available from Oxford Nanopore Technologies.
Further testing the liquid sample to determine pH, temperature, and level of nutrients present in the liquid sample.
Analyzing the data from the microorganism population and determining that there are microorganisms present in the subterranean formation, but that less than 1% of the microorganisms present produce hydrogen. Adding 1-50 barrels of -10e cells/nnL of a nonnative hydrogen producing microorganism, such as Clostridium spp., which is known to be a hydrogen producing organism and compatible with a pH of 5-8 and temperature of 25- 35°C (77-95F), until the amount is projected to be over 20% of the total microorganisms present. Suitable Clostridium can be purchased from ATCC, which is located in Manassas, VA.
Harvesting an amount of hydrogen by pumping the gasses from the subterranean formation through the hydrogen selective filter into a hydrogen storage tank at a rate of about 0.3 tons/hr to 30 tons/hr, wherein the percentage of hydrogen in the gas sample is increased by at least 10%.
