Dewey County, OK
Date: 2/14/24
Operator: Calcuta Petroleum
Well / Area: SCU 43-1
Field:
Unknown
Parish/County: Dewey County, OK
Rig: Atlas 2

Challenges:
Operator drilling a 8,600’ vertical well in the Cottage Grove formation , running WBM, lost full returns 200’ off bottom, tried multiple different pills and nothing worked, tried mixing up a 50ppb pill of generic LCM products because nothing they had could be pumped @ higher concentrations so this is when we were called in.

Solutions/ Product

Recommendation:
They spotted the 50ppb pill 1000’ off bottom and began tripping out of hole and finally got returns inside surface casing. They tripped back in basically with full returns until they washed through the pill they left in hole and had 100ppb pill of our products mixed, we spotted 50bbls or our pill and as soon as it turned the corner full returns were established and dropped off to 50% returns on next trip in, stopped and pumped another 20bbl pill and established full returns to continue tripping in hole.

Products used –
PRO V+, PRO X, PRO HG, PRO Sweep Aid, SB SuperCeal

Results:
Plan continued to be successful drilled to TD, then spotted a couple of PROCOR pills near bottom to POOH to run casing. Spotted 80bbls @ 65ppb to run casing, had full returns running casing and full returns on cement job using PRO V+ Pre-Cement Spacer.

Blaine County, OK

Operator: Longfellow Energy
Well / Area: Nova 3031 #1MHX
Field: Okeene
Parish/County:
Blaine County, OK
Rig: Atlas 5

Challenges:
Having losses, unable to keep hole open, ratty formation top of curve needed to increase mud weight to keep hole open to POOH to run casing. Using conventional mud product treatments with no success unable to keep hole open.
When arrived on location rig was circulating with no losses and mud weight at 9.8ppg but could not raise mud weight needed to get out of hole. Rig crew had 69 bbls of rig fluid in pre-mix tank ,  which holds 80bbls. Recommended pumping an 80 bbl @ 50ppb pill at top of curve. Operator followed the proposed recommendation.

Solutions/Recommendations:
Ratty formation LCM squeeze – 80bbls @ 50ppb: -Pull 70bbls system mud; Add 70sx Pro V+ (20ppb); Add 70sx Pro X (20ppb); Add 20sx Sweep Aid (5ppb); Add 20sx SB Superceal (5ppb); Top off to full 80bbls and agitate. Spot pill just above or across “ratty formation ” at top of curve. POOH to above slurry, circulate 5bbls to ensure tools are clean then let slurry set for 1 hour for solids to settle. After 1 hour make sure annulus is full, if required to fill, fill in 20bbl increments to keep hydrostatic minimal. Once annulus held full, close annulus and started pumping slow as possible in 2-3bbl increments, building pressure in 100psi increments to desired pressure of 200psi. Refer to squeeze graph. Once desired pressure was achieved, opened annulus and started circulating and dusting up system to desired weight to keep hole open. Once desired weight was achieved, 10ppg, circulate a bottoms up. At this point slowly washing to bottom to clean up hole prior to POOH to run pipe.

Results:
Job was successful. After finishing the last squeeze started weighting up mud to 10ppg, returns were at 100 percent. After weighting up, tripped/washed back to bottom with minimal issues, encountered a few tight spots on way out but no losses and company man stated “this was the best shape the hole has been in since the issues started”. Ran casing to bottom with no issues and cemented with full returns.

Operator: Trinity Operating
Well / Area: Clay 4-15 22H
Field: North East Colgate
Parish/County: Coal County, OK
Rig: Latshaw 42

Challenges:
Operator anticipating fluid losses had products on location and did experience significant fluid losses prior to product applications.

Solutions/Recommendations:
PROCOR recommended 50-100bbls containing 65ppb/ 25ppb PRO V+, 25ppb PRO X , 5ppb SB SuperCeal, 5ppb PRO Sweep Aid)

Results:
Operator experienced significant fluid losses and where able to minimized losses by following product recommendation.

Hughes County, OK
Date: 11/30/22
Operator: Trinity Operating
Well / Area: Woodruff 1-24 25H
Field: Woodford
Parish/County: Hughes County, OK
Rig: Latshaw 42

Challenges:
Operator drilled through an unexpected fault and plugged drill pipe pumping conventional LCM products before PROCOR arrived. After 3 days of fighting losses Geology confirmed they drilled through a large fault causing total losses and gas influx, not a normal loss zone and not the fractured shale gas bearing formation they assumed.

Solutions/Recommendations:
Spot 50-100 pill containing: 80ppb – 35ppb PRO V+, 35ppb PRO X, 5ppb SB Superceal and 5ppb PRO Sweep Aid. Regained full returns and engineer released. As engineer left location, attempted to begin pulling plugged DP and well started losing again. Engineer was turned around to go back to the rig. A second 80bbl @ 80ppb pill was pumped with no success. We then held a conference call to discuss go forward plan. Plan was to utilize the most aggressive LCM pill we had available. It was decided to go with ½ the OH volume (240bbls @ 100ppb – 33.3ppb Pro V+, 33.3ppb PRO X and 33.3ppb PRO HG(hydrogel))

Results:
Once the 240bbls @ 100ppb was spotted, we finally began to get pressures to come down by 4-500psi each pump in and after pumping about 100bbls well stabilized to zero psi killing well, annulus held full and minimal gas. They were able to pull the plugged DP, saving the BHA and run casing. They thought for sure Drill Pipe would be stuck but we explained how the product works, can’t stick you if the BHA and bit or not near the loss zone where it is dewatering.
Notes on Preventative plan of action after the well was dead:
Treated active system with 10ppb SB SuperCeal and 10ppb PRO Sweep Aid. Once system was treated, we recommended maintaining treatment with addtions of 5sx each per hour.

Recommended Sweeps of 20 bbls every 200-200’ Sweep can be pumped as needed, consisting of 10-15bbls every 200-300’@ 20ppb (10ppb PRO Sweep Aid and 10ppb SB SuperCeal). This sweep regimen enhanced hole cleaning, resins coated andkept shales in good shape preventing reactivity, prevents seepage to moderate losses, enhance filtration control of the mudand help keep the well bore in gauge mixing up 80bbls at a time of sweep slurry @ 20ppb. Also ran PRO V+ Pre-Cement Spacer ahead of cement 80bbls @ 80ppb.
