In October 2017 the operator noted bubbling in the cellar and the well was shut in for a surface casing leak with a leak depth of 58”. A conductor top job with LockCem was executed in January 2018 without success. In June of 2020 an OA cement job was performed with squeezecrete. In November 2020 a patch was welded over the conductor and subsequently squeezecrete was pumped into the conductor through the patch. The patch established a leak post squeezecrete job. In March 2021 the patch was removed from the conductor and the area was cleaned. A second patch was then welded to the conductor and the well was popped. During the under eval period the OA and patch had minimal pressure build up while online but we continue to have small amounts of residual fluid entering the conductor flutes while online. The intent of this procedure is to install an engineered clamp to contain the conductor fluid and create a monitorable & bleedable void above the conductor flutes. 14-24A has a passing MIT-IA to 2458 psi from May 2018 and a passing CMIT-TxIA in March of 2021 to 2390 psi. Procedure: DHD: 1. Clean and buff conductor bowl & wellhead per Northern Solutions. Remove all residual fluids from the conductor bowl/flutes. Special Projects: 1. Install surface clamp as outlined in drawings below. a. Installation to include: i. One wireless pressure gauge ii. One Needle valve with drain hose iii. Lock down screws installed into the conductor bowl groove. 2. PT to 20 psi for 5 minutes with diesel. Operations/Well Integrity: 1. Establish wireless alarm at 10 psi tied into the SCADA system. 2. Bleed clamp annulus to 0 psi. Pop well. Monitor w/ DHD during pop. 3. Verify clamp contains all fluid leaks. SAG CTD sidetrack 00 14-24A Wellhead Clamp 4. Ops to bleed clamp annulus as necessary during operation. 5. Turn well to operable.

The operator noted bubbling in the conductor on 10/23/17. SL secured the well with a plug and the well has a passing MIT-T to 2336 psi and a passing CMIT-IA to 2388 psi. The OA failed to catch pressure when an MIT-OA was attempted. Leak depth detection confirmed a 1gal/min surface casing leak @ ~ 58.5". A conductor top job with LockCem was executed to fix the SC leak on 1/28/2018 per the previous Sundry approval. A 10- 404 was submitted to close out this Sundry. The well was POP in April of 2018 but still leaked fluid from the Conductor flutes so an OA downsqueeze will be needed to repair the SC leak. A CMIT-TxIA passed to 2419 psi on 11/23/2019 and a MITT passed to 2336 psi on 10/24/2017. A previous Sundry was approved for a Surface Casing Excavation and patch repair. That Sundry can be cancelled with this one in its place. Current Status The well is Not Operable well due to SC leak and is secured with a TTP. Objective Perform an OA downsqueeze to seal off the SC leak. Procedural steps DHD/Special projects 1. Pump sealant (squeezecrete, Well Lock, or similar product) into the OA. 2. Squeeze sealant into the SC leak. 3. Wait on sealant to cure. Slickline 1. Run LGLVs. 2. Pull TTP. DHD/Well Integrity Engineer 1. POP well Under-Evaluation and monitor SC/Cellar for any leakage. 2. If there is no leakage, convert well to Operable status. 2 1 Carlisle, Samantha J (CED) From:Rixse, Melvin G (CED) Sent:Wednesday, May 6, 2020 4:09 PM To:Lastufka, Joseph N Cc:Carlisle, Samantha J (CED) Subject:RE: 14-24A (PTD #216-057) Sundry # 319-367 Joe, Okay.

The pressures were confirmed to be T/I/0=2100/2110/Opsi. Attempts to bleed the annulus resulted in a rapid repressurization confirming TxIA communication. The plan forward is to have slickline replace the gas lift valves in order to restore tubing integrity. If the tubing integrity cannot be restored the well will be secured with a tubing tail plug. To give some background 14-24 was initially classified as not operable on 10/29/17 for having a surface casing leak,arid then again on 5/2/18 when a conductor top job failed to mitigate the surface casing leak. The well has had no recent history of TxIA communication and was not immediately secured on 5/2/18 due to ongoing work to diagnose and repalir the SC leak.

The operator noted bubbling in the conductor on 10/23/17. SL secured the well with a plug and the well has a passing MIT-T to 2336 psi and a passing CMIT-IA to 2388 psi. The OA failed to catch pressure when an MIT-OA was attempted. Leak depth detection confirmed a 1 gal/min surface casing leak @ - 58.5". The objective of this job is to perform a conductor top iob to fix the SC leak with a contingent OA downsqueeze if the top job repair is unsuccessful. The top job was-performed on 1/28/2018 per the previous Sundry approval. A 10-404 was submitted to close out this Sundry. The well was POP in April of 2018 but still leaked fluid from the Conductor flutes so the OA downsqueeze will be needed to repair the SC leak. Current Status The well is Not Operable well due to SC leak. Objective Perform an OA downsqueeze to cement the OA from the inside out and repair the SC leak. Procedural steps Fullbore 1. Establish injectivity rate and pressure with diesel or crude oil down the OA and into formation. Max A pressure 2500 psi. 2.

The operator noted bubbling in the conductor on 10/23/17. SL secured the well with a plug and the well has a passing MIT-T to 2336 psi and a passing CMIT-IA to 2388 psi. The OA failed to catch pressure when an MIT-OA was attempted. Leak depth detection confirmed a 1gal/min surface casing leak @ — 58.5". The objective of this job is to perform a conductor top job to fix the SC leak with a contingent OA downsqueeze if the top job repair is unsuccessful Current Status The well is Not Operable well due to SC leak. Objective Perform a conductor top job to eliminate any leak from the surface casing (OA). If the top job is unsuccessful then perform and OA downsqueeze to cement the OA from the inside out and repair the SC leak. Procedural steps DHD/Special projects 1. Steam clean the Conductor x Surface Casing Annulus to top of good cement. 2. Circulate Cement or LockCem into the conductor from the top of existing cement to surface until clean cement returns are observed. Operations/DHD 1. POP the well Under Evaluation and monitor the conductor/cellar for bubbling and sniff for LELs to determine Operability status. • S The following steps are contingent upon whether or not the SC leak is fixed. If the SC leak is not fixed proceed with the following: Fullbore 1. Establish injectivity rate and pressure with diesel or crude oil down the OA and into formation. Max OA pressure 2500 psi. 2.

On 10/25/17 slickline secured the well with a tubing tail plug and fullbore performed a passing MIT-T to 2,337psi and CMIT-TxIA to 2387psi. DHD confirmed the surface casing leak on 10/26/17 with nitrogen and determined the leak depth to be approximately 58.5" below the OA casing valve. At this time the well is classified as Not Operable and will remain shut in and secured. The production engineer will evaluate the well for repair.
