G. In the event that work is required on any well,including but not limited to plugging and abandoning, reabandonment, cutting off casing,or adding a riser,written permission is needed from the Division. r H.All conductors must be plugged with cement and leak tested by a Division inspector. I.The outermost casing stub of all wells within the construction site should be maintained within 5 to 10 feet below the surface of the final grade.The casing can be cut off or a riser added to achieve the required depth. ALL WELL WORK MUST BE COMPLETED BEFORE ANY CONSTRUCTION-SITE PLAN APPROVAL IS ISSUED. Construction-Site Plan Requirements To conduct a review,the Division requires three copies of the plan along with a completed Construction-Site Review Application(PDF)that must be submitted to the appropriate Division district office. Following well-location verification and testing,the applicant must correctly plot the well location on the construction-site plan map. Each well must be identified with the official name of the company/operator and the well designation.Wells in proximity,but outside the construction site,should also be plotted to verify their locations. The construction-site plan should indicate the property and/or construction site boundaries,footprints of proposed structures,and existing structures that will remain.Also,existing and proposed oilfield facilities(tanks,processing equipment,enclosures, pipelines,etc.)that will be operating on the site after completion of the proposed development should be included. The applicant should include a description of the existing type and height of all facility enclosures(e.g.,fencing) r. and list any modifications that are part of the construction-site plan. Any conductor casing found on the site must be plotted on the construction-site plan and listed on the Construction-Site Plan Review. Conducting Gas Tests on Wells ` The Division requires that all accessible wells be located and tested for gas and/or oil leakage. Division staff conducts the test using the following guidelines: 1. Standing Water Test: Cement that is flush with the top of the casing is chipped down so that water poured on top is allowed to pool.This test consists of observing any bubbling through standing water in the casing and annular spaces. If bubbling is noted,the source of the bubbling must be ascertained. If the bubbling is from air displaced from micro fractures in the cement,the bubbling will cease within a short time. 2. Soap Test:A soap solution is sprayed on all exposed portions of the wellhead.Any bubbling is tested for combustible gasses with a sensitive testing instrument. 3. Bag Test:This test involves attaching a plastic bag over the casing and testing the vapor in the bag with a _ sensitive testing instrument.This method can be used in an empty annulus prior to approving a surface pour. If there is any indication of oil or gas leakage,or if the surface plug does not have competent cement in the casing and/or annular spaces,the well needs to be reabandoned. Obtaining a Permit to Work on a Well If any well requires plugging work or extending or cutting casing,and that well has been previously plugged and abandoned,the applicant must file a Supplementary Notice(to Abandon)(Form OG123R)(PDF)with the appropriate district office. If the well has not been previously plugged and abandoned,then a Notice of Intention to Abandon(Form OG108)(PDF)must be fled with the appropriate district office.When the well work is completed,a Report of Operations(Form OG109)will be issued.
