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.

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.

Field: Spraberry (Trend Area)

Rig: H&P 487

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 experiencing fluid losses while drilling. Solutions/ Product

Recommendation:

They were pumping 30ppb sweeps to help with losses while drilling. Decision was made to mix up an 80ppb pill and spot with a light squeeze. Started with 40ppb (10ppb PRO Sweep Aid, 10ppb SB SuperCeal, 10ppb PRO V+, 10ppb PRO X) and increased to 80ppb. Decision was made to sweep the hole with the 80ppb pill and run liner.

Results:

The 80ppb sweeps fixed the losses and products were pumped through tools with no problems.

Field: Spraberry
Parish/County: Andrews County, TX
Rig: HP 248

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:
Having torque issues while drilling with Water-Based mud in the lateral section of the well.
Solutions/Recommendations:
To run 3-5% by volume of PRO Slide into the active system to decrease torque and allow for smooth drilling.

Results:
Torque decrease with 4% by volume an average of 4-7K and drilling was completed.

Rig: Patterson 256

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.
