Parish/County: Webb County, TX
Rig: H&P 536

Challenges:
The operator drilled out of intermediate casing and attempted to obtain a casing shoe test of 17.0 EMW but was unsuccessful with the pressure leaking off.

Solutions/ Product Recommendation: This Operator is familiar with running our products did not reach out to PROCOR for assistance or recommendations on squeezing the shoe, so they mixed and squeezed an 80bbl pill with 25ppb SB SuperCeal, 30ppb Calcium Carbonate-30 and 30ppb Calcium Carbonate-50ppb.

Results:
The operator was only able to achieve a maximum squeeze of 15.1ppg EMW with the mud engineer’s pill combination. The operator decided to drill ahead with a maximum mud weight of 14.6ppg while pumping preventative sweeps of 10ppb PRO Sweep Aid and 10 ppg Calcium Carbonate every 100ft drilled. The operator was able to drill to the pilot hole TD with no losses. After the fact, we informed their mud engineer we would have recommended pumping, 40ppb PRO X, 30ppb
PRO V+ and 10ppb SB SuperCeal, but we’re concerned about plugging the directional tools. We explained we have pumped this concentration many times and offered to go out to location and assist. The mud engineer was convinced they had a bad cement job on the intermediate casing string.

County: Reeves County, TX
Rig: Savanna Rig 650

Challenges:

Operator experiencing water flow during cement job channeled through cement to surface. First set of perferations and new cement did not stop the water flow.

Solutions:

PROCOR recommended 40 bbls @ 80ppb: Pulled 38 bbls water. Add 1-2 sacks fresh water gel and allow to yield for product suspension, Added 48 sxs PRO V+ (30ppb), Added 48 sxs PRO X (30ppb), Added 40 sxs PRO HG (40ppb). Should yield 40 bbls @ fluid weight. When the squeeze packer was set, began pumping the slurry down the casing as the lead cement Aggressive LCM pill as recommended by the cement company. Once the cement was in place allowed recommended wait time by cement company no less than 4 hours for the PROCOR lead slurry. During the wait time, the hydrogels continued to absorb the water flow, preventing contamination or thinning of the cement by the water allowing it to set up and provide full compressive strength for the test.

Results:

Pressures were constant during pumping procedure and flow was not an issue. This application was basically pumped to stop a slight water flow, absorb water and act as a median allowing the cement to set up.

Lea County, NM
Rig: Nabors 895

Challenges:

While drilling ahead in 7.875’’ lateral section at 13,342’ MD, we experienced a noticeable drilling break and nearly immediate full losses which are suspected to be related to a fault zone. We continued dry drilling while pumping 30 ppb LCM sweeps until partial returns were established resulting in ~150 bph losses. As we continued drilling ahead, we traversed another suspected fault zone at 13,777’ MD resulting in similar drilling break & full losses. LCM treatments continued and partial returns were re-established with losses now at ~280 bph. As we continued drilling ahead to 14,929’ MD, we experienced a reduction in the loss rate to approximately 65 bph prior to a bit trip. During the trip out, we experienced sporadic overpull through the losses intervals which in turn resulted in losing fluid on the trip out – likely having ripped the LCM scab off. Currently, we are tripping back in hole and experiencing some minor wellbore instability likely resulting from the hole’s inability to hold a column of fluid. We have approx. 1,300’ to TD on this well prior to running our 5.5’’ production casing.

Solutions/ Product

Recommendation:

If still drilling to TD upon product arrival, we recommend a strict sweep regimen through TD of the sections. Begin pumping sweeps every connection or as the prior sweep exits the bit. Sweeps should be 10-20bbls @ 65ppb (25ppb PRO V+, 25ppb Sweep Aid, 5ppb SB Superceal and 5ppb Sweep Aid). This sweep regimen will enhance hole cleaning, resins will coat and keep shales in good shape preventing reactivity, prevent minor seepage to moderate losses, enhance filtration control of the mud and help keep the well bore in gauge. 80bbl sweep slurry @ 65ppb
•Pull 70bbls system mud to slugging pit•Add 80sx PRO V+ (25ppb)•Add 80sx PRO X (25ppb)•Add 16sx PRO Sweep Aid (5ppb)•Add 16sx SB Superceal (5ppb)•Top off to full 80bbls and agitate, pump sweeps as needed.At TD if losses have occurred while drilling, we recommend spotting 50bbls @ 80ppb (35ppb PRO V+/35ppb PRO X/5ppb SB Superceal/5ppb Sweep Aid) across the area where suspected losses occurred prior to POOH to run casing. Mix and pump same pill ahead of cement to ensure returns on cement job.

Lessons Learned:

Would recommend going back up to the lost zone and squeezing the product into the formation to get a better seal in the zone.

Challenges:

Drilling the intermediate section on the 9H at 6,845’ with WBM and previously running a competitors lube which was blinding off the shakers causing mud losses and having to slow down.

Solutions/Recommendations: Recommended PRO Slide Synthetic Based Drilling Lubricant. Plan was to run PRO Slide in the production lateral with 2% in the active system and spotted 600 bbls in the lateral at TD to POOH and run casing. Results: Lubricant worked well by not blinding over the shakers. Decreased torque enough to help drill faster, allowing the use of WBM through out the well until total depth and the decrease of torque was between 12-20%. Spotting PRO Slide lubricant pills before running casing allowed for casing run to be smooth.

Challenges:
Operator did not get a good FIT and decided to apply PROCOR’s squeeze product to increase formation integrity to correct pressure.

Solutions/Recommendations:
Recommended preforming squeeze by closing well in and Bull heading fluid into the wellbore.
•We recommend starting off with 10-15bbl sweeps @ 50ppb sweeps every 100’ or as needed (15ppb Sweep Aid, 5ppb SBSuperceal, 15ppb PRO V+ and 15ppb PRO X). Utilize these sweeps from KOP to landing curve.
•Build 80bbl 80ppb pill and spot just above lost zone. Pill will consist of (PV+ 30 ppb, PX 30 ppb, PRO Sweep Aid 10 ppb,SB SuperCeal 10 ppb)
•We recommend spotting a pill across the loss zone and squeezing fluid into the formation till pressure required isachieved.

Results:
Improved FIT results to 9.8 ppg ECD (Equivalent Circulating Density) but needed to get 11.0 ppg ECD. Decision was made to go back in and continue drilling and bring weight of fluid up as need slowly. Will continue to sweep hole with sweep recommendation.

Challenges:

Operator lost returns at approximately 4,456’ and continued drilling for another 4,000’ before calling out. Once we arrived on location operations were drilling ahead with no returns. Plan was to pump sweep down to regain returns and finish drilling to casing point. Talked with representatives on location and it was decided that the highest concentration would be 40 ppb, set up 30 bbl sweeps of the 40 ppb consisting of PRO V, PRO X, and SB SuperCeal. Once sweep was pumped there was a noticeable rise in pump pressure, but no returns. The gain in pump pressure stayed until they decided to TOH to change out bit and motor due to low ROP. Before TOH they spotted a 40 ppb 80 bbl pill down around 4,400’ to let soak while changing BHA. Pill did not regain returns.

Solutions/Recommendations: Spotted a pill consisting of 40 pounds per barrel (PRO X 15 ppb, PRO V+ 10 ppb, SB SuperCeal 5 ppb). Products used , PRO V +, PRO X, SB SuperCeal.

Results:

Operator finished drilling interval without returns, but maintain sweeps.

Recommendation:
PROCOR recommended pumping a squeeze pill of 80bbls at 80ppb using 50% PRO V+ and 50% PRO X and PRO V+ @ 40ppb and
PRO X @ 40ppb.

Results:
Minor fluid seepage continued same as last well we had just squeezed off so we spotted another 80bbls @ 80ppb. We just achieved 13ppg EMW with about 30bbls in formation. Plan is to bump up a couple more times to get our back-end bleed down a little higher. Top end holds 690-700psi perfect, bleeds down to about 560 after 1hr, so now we were trying to get the back end to settle a little higher. Mud weight to drill to TD is 10.8 – 11.2ppg which would stay below squeeze EMW and was another successful application.

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.

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.
