H.W. PARKER BY A ATTORNEYS rates This invention relates to an improved process for initiating in situ combustion in a carbonaceous stratum.
In situ combustion in the recovery of hydrocarbons from underground strata containing carbonaceous material is becoming more prevalent in the petroleum industry. In this technique of production, combustion is initiated in the carbonaceous stratum and the resulting combustion zone is caused to move thru the stratum by either inverse or direct air drive whereby the heat of combustion of a substantial proportion of the hydrocarbon in the stratum drives out and usually upgrades a substantial proportion of the remaining hydrocarbon material.
The ignition of carbonaceous material in a stratum around a borehole therein followed by injection of air thru the ignition borehole and recovery of product hydrocarbons and combustion gas thru another borehole in the stratum is a direct air drive process for effecting in situ combustion and recovery of hydrocarbons from the stratum. In this type of operation the stratum usually plugs in front of the combustion zone because a heavy viscous fluid bank collects in the stratum in advance of the combustion zone which prevents movement of air to the combustion process. To overcome this difliculty and permit the continued progress of the combustion zone thru the stratum, inverse air injection has been resorted to. By this technique, a combustion zone is established around an ignition borehole by any suitable means and air is fed thru the stratum to the combustion zone from one or more surrounding boreholes.
In operating With either direct or indirect air injection to produce hydrocarbons from a carbonaceous stratum by in situ combustion, it is necessary to first ignite the carbonaceous material in the stratum around a borehole therein. One method of ignition utilizes a downhole heater of either the electric or gas fired type to heat the wall of the ignition borehole and an annular section of the stratum surrounding the borehole. Another technique comprises placing charcoal in the ignition borehole adjacent the stratum to be ignited and burning the charcoal therein by igniting same while feeding O -cOntaining gas thereto. In any of these processes for igniting the carbonaceous stratum, a long preheating period is necessary to bring the temperature thereof up to ignition temperature, which is usually in the range of about 550 to 700 F. when contacting the hot stratum with air as the O containing gas. This invention is concerned with a method whereby the preheating period is substantially reduced.
Accordingly, the principal object of the invention is to provide an improved process for initiating combustion in a carbonaceous stratum. Another object is to reduce the preheating period required prior to the ignition of a carbonaceous stratum. A further object is to provide an improved method of controlling the ignition of a carbonaceous stratum to be produced by in situ combustion. Other objects of the invention will become apparent upon consideration of the accompanying disclosure.
A broad aspect of the invention comprises heating a section of a stratum containing combustible carbonaceous material to bring the same to ignition temperature and, while preheating said section, contacting the same with a stream of O -containing gas under controlled flow conditions.
'Air or other o -containing gas is passed to the section of stratum being heated during the heating step, at a slow rate during the initial phases of the preheating and at a faster rate during the later phases thereof. The floW of air to the preheated area is regulated by analyzing the effluent therefrom for either 0 or CO and by controlling the rate of air flow so as to maintain the 0 concentration in the range of about 0.10 to about 10% by volume; or, when analyzed for CO concentration, regulating the flow to maintain the concentration of CO in the range of about 6 to 13 or 14% by volume. If the O concentration in the effluent exceeds the desired upper limit in the range of 0.10 to 10% by volume or if the concentration of CO in the efiiuent gas falls below a minimum in the range of 6 to 14% by volume, the fiow rate of air thru the stratum is decreased to bring the concentration of 0 or CO to a level in the preceding ranges. Conversely, if the 0 concentration in the efl iuent gas falls below a minimum in the range of 0.10 to 10% by volume, or if the CO concentration in the efiiuent gas exceeds a maximum in the range of 6 to 14% by volume. then the rate of how of air thru the heated stratum is increased. In other words, the concentration of either 0 or CO in the effluent gas is determined and the fiow rate of air is controlled so as to maintain the concentration of these constituents in the above ranges.
It has been found that by contacting the heated section of stratum during the preheating step with O and controlling the flow of 0 so as to maintain a low oxygen concentration (and high CO concentration) in the efiiuent from the heated section, the time required for establishing ignition of the stratum can be reduced at least in half. By this method the allowable rate of flow of O continuously increases during the preheating thus permitting self-sustaining ignition to start without the sudden shock of operating the ignition well after a long period of being shut in and the associated problems of flashing water to steam or a sudden rush of cold tar and water into the heated zone, particularly, when the inverse air injection method is utilized, with the ignition well serving as a production well.
It has been found that slow oxidation occurs during the early phases of the preheating step when air is fed to the heated area and, as the temperature of the stratum rises, the rate of oxidation increases. For this reason, it is feasible to preheat the section of stratum around an ignition borehole therein to raise the temperature thereof to about 200 to 300 P. (such as 250 F.) before contacting the same with a stream of air. However, air may be flowed to the section of stratum during the entire preheating period at increasing rates, as required to maintain the proper oxygen concentration in the eifiuent, so that when the ignition temperature is reached, ignition is automatically effected. In cases where a heating device is utilized for the preheating step, the same is removed when ignition is established.
Control of the 0 or CO concentration in the efiiuent from the section of stratum being heated automatically determines the air flow rate at any given time. Flow rates will vary widely during the preheating period probably because of the changing rate of oxidation of carbonaceous matter.
A rate as low as l or 2 standard cubic feet per hour per square foot of well bore area in the carbonaceous stratum comes within the scope of the process and rates will go as high as 200 s.c.f.h. per square foot of borehole area and higher, depending upon the permeability of the stratum and the character of the carbonaceous deposit therein.
A more complete understanding of the invention may be had by reference to the accompanying schematic drawing of which FIGURE 1 is an elevation showing an arrangement of apparatus in association with a carbona- 3 ceous stratum for effecting the process of the invention; FIGURE 2 shows a typical S-spot well pattern adapted to the process of the invention; and FIGURE 3 is a graph showing the relation between time and preheat temperature in preheating a section of carbonaceous stratum with and without air flow.
Referring to FIGURE 1, a carbonaceous stratum 10 is penetrated by an ignition borehole 12 and a number of injection boreholes 14 two of which are shown. Boreholes 14 are spaced, as shown in FIGURE 2, around borehole 12 in a generally annular pattern and spaced therefrom any suitable distance within the range of a few feet to several hundred feet, depending upon the permeability of the carbonaceous stratum and other factors. It is to be understood that, where the permeability is low, the stratum may be horizontally fractured in known manner.
Each well is provided with a casing '16 and a well head 18. A heater 20 is positioned in borehole 12 within stratum 10 so as to heat the wall of the borehole Within the carbonaceous stratum. Heater 20 may be of any type such as a gas fired heater, an electric heater, or a mass of incandescent charcoal. One type of gas fired heater which has been found particularly effective is that disclosed and claimed in the US application of A. S. Rogers et al., Serial No. 719,890, filed March 7, 1958. Charcoal has also been found to be very effective in preheating a carbonaceous stratum surrounding a borehole for in situ combustion purposes.
FIGURE 3 shows curves plotted from laboratory tests on igniting tar sand on a small scale oil well arrangement. In the tests, a section of tar sand 4 /2 inches thick and 7 inches in diameter was clamped between two flanges so that air could be forced into the sides of the cylinder thru the cylindrical surface and produced from a well drilled along its axis. This gave a system of radial fiow similar to that employed in field operations. The rock or sand was heated by means of an electric heater in the well bore. In tests in which the well bore was preheated without flow of air thru the rock during the preheating operation, the time for heating to ignition temperautre was of the order of 40 minutes. In another test with the same arrangement of apparatus and tar sand, air was fiowed thru the sand during the preheating operation and the effluent gas from the well bore was analyzed for carbon dioxide. (A continuous oxygen analyzer was not available in the laboratory at the time.) The flow of air was controlled to maintain a carbon dioxide concentration in the range of 6 to 13 percent in the effluent gas from the well bore. A temperature of 600 F. (the approximate ignition temperature) was reached approximately 2 /2 times as rapidly as in the tests without air flow, as measured by a thermocouple one-half inch from the well bore. runs are plotted and shown in FIGURE 3.
Certain modifications of the invention will become apparent to those skilled in the art and the illustrative details disclosed are not to be construed as imposing unnecessary limitations on the invention.
