When a Form 10 -403 is submitted requesting approval to plug a well for redrill, the initial reviewer (Art or Steve D.) will check to make sure that the "Plug for Redrill" box in the upper left corner of the 403 form is checked. If the "Abandon" box is checked, we will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). 2. On the Form 10 -403 if "Abandon" is checked in Box 15 (Well Status after proposed work), Art or Steve y D. will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). Instead, we will check the "Suspended" box. Guy and Winton will serve as quality control for steps 1 and 2. 3. When Steve McMains receives the Form 10 -403 with a check in the "Plug for Redrill" box, he will enter the existing code "IBPRD" into RBDMS. This code automatically generates a comment under the History tab stating "Intent: Plug for Redrill." 4. When Steve McMains receives any Form 10 -407, he will check the History tab in RBDMS for this comment. If he sees the "Intent: Plug for Redrill" code, and cannot find any evidence that a subsequent re -drill has been COMPLETED, he will assign a status of SUSPENDED to the well bore in RBDMS, no matter what status is listed on the 10 -407. Steve will also change the status on the 10 -407 form to SUSPENDED, and will date and initial his change. If Steve does not see the "Intent: Plug for Redrill" comment or code, he will enter the status listed on the Form 10 -407 into RBDMS. 5. When the Form 10 -407 for the redrill is received, Steve M. will change the original well's status from suspended to abandoned. 6. The first week of every January and July, Steve M. and Steve D. will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, Steve M. and Steve D. will also review the list of suspended wells for accuracy.

Displace well to new mud after setting whipstock. Higher hole angles increase the probability of cuttings bed formation. Monitor LSRV of the drilling fluid with a Brookfield Viscometer. Maintain a 1 minute LSRV of > 50,000 with FIo-Vis additions. Control solids by running the finest shaker screen size possible. Run centrifuge for removal of fine solids... Keep mud weights as Iow as possible. Mud weights should range from 8.55 ppg to 8.75 ppg. Note: Higher mud weights may be required. Report drill solids analysis on mud check sheet. Report hydraulics calculations on mud check sheet. Lo-Ware should be used as needed for a bridging agent to control seepage losses. NOTE: Maximum recommended Lo-Wate concentration for discharge purposes is 75 ppb. Flotrol should be used as needed for fluid loss control. NOTE: Maximum recommended Flotrol concentration for discharge purposes is 3 ppb. If torque is a problem. Lubetex should be added. Monitor decrease in torque with each % addition of Lubetex.
