Noble County, OH
Date:` 3/1/25
Operator: Encino Energy
Well / Area: Bears NB BUF 205H
Field: Unknown
Parish/County: Noble County, OH
Rig: Patterson 579

Challenges:
Preventative sweeps are working but as they pass and seepage comes back @ 525gpm. They can drill with 500gpm but the directional tool company needed 525gpm to steer so Operator decided to treat the system with preventative WBSM products.

Solutions/Product Recommendations:
We recommended treating the system with 7ppb SB SuperCeal and 3ppb PRO Sweep Aid Results Completed system treatment , no losses, even increased MW to 12ppg.

Note:
Operator decided to pump sweeps and not squeeze since they didn’t have losses when they displaced and decided to not use the squeeze products to determine if the squeeze was working and determined squeeze application was obviously working.

Well / Area: Stitt 1H
Field: Utica Shale
Parish/County: Harrison County, OH
Rig: Patterson 571

Challenges:
Expecting Coal section @ 381’ and water flow @ 750’ , ensuring a good cement job.
Solutions/ Product

Recommendation:
After running 8.75” csg, operator runs 80 bbls @ 100 ppb of PROCOR WBSM/ LCM across and through top of Clinton formation, then perform squeeze to 12.3 EMW once back to shoe. Also pumping 65ppb sweeps in lateral section. Mixed sweeps at 65 ppb consisting of 25ppb PRO V+ 25 ppb PRO X, 5 ppb SB SuperCeal and 5ppb Sweep Aid. Currently pumping 20 bbl sweeps every 200-300′ or as needed to control fluid loss and help with cleaning wellbore.

Results:
Successfully drilled well to TD.

Arrived on location 10/27/24, Check in with Co Man. Currently drilling ahead with occasional losses of 10-40 bbls/hr.
Solutions/ Product

Recommendation:
Cut back pre-mixed pill from 100 ppb to 50 ppb of PROCOR LCM, pumped in 30 bbl sweeps. Losses reduced, mixed sweeps at 40 ppb consisting of 15 ppb PRO V+ 15 ppb PRO Sweep Aid and 10 ppb SB SuperCeal. Currently pumping 20 bbl sweeps every 200-300′ or as needed to control fluid loss and help with cleaning wellbore.

Results:
Drilling ahead at report time at 250-300 ft/hr with little to no fluid loss.

Date: 8/12/24
Operator: HG Energy 
Well / Area: Winans 1216 N-5H
Field: unknown
Parish/County: Lewis County, WV
Rig: Patterson 611

Challenges:
Operator drilling the curve , starting losing fluid @ 100 bbls per hr.

Solutions/ Product

Recommendation:
PROCOR recommended 50bbls (20ppb SB SuperCeal / 25ppb PRO V+). Products used – PRO V+, PRO X, SB SuperCeal

Results:
Pumped pill and achieved full returns, drilled the 24,000’ lateral with no more losses.

Operator: Encino Energy
Well / Area: David Weaver HN STO 6H
Field: 
Parish/County: Harrison County, OH
Rig: Patterson 579

Challenges:
Operator experiencing fluid losses.

Solutions/ Product

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.

Belmont County, OH
Date: 12/1/23
Operator: Gulfport
Well / Area: Clark 1B
Field: Clark Pad
Parish/County: Belmont County, OH
Rig: Patterson 873

Challenges:
Fluid losses observed while drilling lateral section of well. Goal is to control and stop any and all fluid loss.
Solutions/ Product

Recommendation:
Mud company LCM consisting of cedar fiber and CACO3. Broad range of recommendations given depending on losses. Recommendation followed was our 25 ppb sweep mix. PRO V + at 15 ppb, SBSC at 5 ppb, PSA at 5 ppb totaling 25 ppb for all
sweeps. Products mixed into slugging pit through hopper, then pumped using rig pumps. No problems encountered during this mixing procedure and no issues pumping products through tools or bit.

Results:
After pills were spotted, well went static and returns were achieved at the shoe with no losses. Procedure went as planned and returns were regained; however, decision was made to cement and P&A by management.

Well / Area: Sproul 205h 6078
Field: Utica
Parish/County: Tuscarawas County, OH
Rig: Patterson 580

Challenges:
Prevent / Stop fluid losses in the Clinton formation during intermediate well section.

Solutions/ Product

Recommendation:
PROCOR recommended spotting 80 bbls @ 80 ppb and squeezing formation to desired MWE. Operator followed recommendation using PRO V+ and PRO X both @ 40 ppb.
All products were mixed through the mixing hopper into the slugging pit and pumped using rig pumps downhole. No problems encountered during this mixing procedure and no issues pumping products through tools or bit.

Results:
After spotting and squeezing pill, an acceptable MWE (mud weight equivalent) was achieved, and drilling resumed with no losses. Procedure went as planned and rig was able to drill ahead with no losses while PC Engineer was on location. Superintendent reported after the PROCOR Engineer was released, began weighting up at bottom of curve to drill lateral. This is usually when losses
occur back up in the “Clinton” due to ECD’s. Started w 15bbl sweeps every connection at 45ppb, once 500′ was drilled w no losses, sweeps were reduced to 10bbls every 200′ at 30ppb. Drilled to TD w no further losses or hole issues. Casing was run to bottom slick and cemented with no issues.

Solutions / Products

Recommended:
Recommended 80bbl Pill of our High Solids/High Fluid Loss Squeeze Products which included PRO V+ @ 40ppb and PRO X @ 40ppb.
After successfully squeezing the formation recommended following up with sweeps as needed to keep the “Clinton” coated and sealed. We also included our PRO V+ Pre-Cement application, 50bbls @ 50ppb, Products Used : PV+, PX

Results:
No losses were encountered while filling well with OBM. However, we still spotted 85bbl pill of 80ppb (40ppb PV, 40ppbPX) at the bottom of the Clinton formation. We were able to squeeze +/- 7.5bbls into the formation, achieving a EMW of 13.36ppg. Rig is now drilling ahead with no fluid loss issues.
