GUIDELINE FOR APPLICATION FOR APPROVAL OF DEEP WELL DISPOSAL OF NON-SPECIAL WASTE
- the location and coordinates of the proposed disposal well and justification for the selected location;
- a map showing title holders within a 3-kilometre radius of the proposed disposal well;
- a map showing the status and completion zone for all wells within 3-kilometre of the disposal well;
- a structure map and a gross-isopach map of the pool into which disposal is proposed;
- geological cross-section through the pool, including the disposal well, and showing all gas-oil, gas-water, and oil-water contacts and upper and lower bounding formations;
- a general discussion of the geology of the proposed disposal zone, including details of stratigraphic traps, dip and strike;
- a discussion of the reservoir rock properties including continuity and thickness of base and caprock, evidence of fracturing and comments on the effectiveness of the pool boundaries;
- a discussion of the results of a cement bond log in the proposed disposal well;
- the producing history, if any, of the proposed disposal well, and of the first two rows of wells off-setting it;
- the results of calculations made to estimate drive indices, interface movements in the pool, and injectivity performance of the disposal well;
- a description of the non-special waste to be disposed of, together with an analysis of the formation water in the proposed disposal pool and the results of compatibility studies;
- an estimate of the daily volume of non-special waste to be disposed of, and its effect, if any, on the recovery of oil or gas from the pool;
- a diagram of the proposed disposal well completion showing existing and proposed completion intervals, casing and tubing details, depth of packers and nature of the inhibited fluid to be used in the annulus;
- a diagram of the surface non-special waste handling and metering facilities;
- a general discussion and justification of the need for disposal of non-special waste in the proposed well, and an economic comparison of the options investigated;
- written statements from other parties who may be affected, indicating their reaction to the proposed non-special waste disposal scheme. An example of such a statements is provided here.
