8 Ways to Keep Drilling and Save Millions

March 17, 2020

Gearing up to drill? That’s a tough question to answer right now as oil prices remain uncertain.  Given the shifting economics, many producers are taking a second look at drilling programs and the ROI of new wells. Maintaining drilling momentum in 2020 is all about optimizing field spending and Corva is perfectly poised to help drillers do just that with our integrated platform of drilling and completion apps, laser-focused on maximizing capital efficiency.

From optimizing performance across the rig and getting the most mileage out of equipment to pumping more stages in a day and preventing wireline mistakes, here are 8 ways your team can save millions this year along with real-world examples of how Corva’s clients are saving big.  Corva is your partner in driving capital efficiency to new heights, enabling you to sustain drilling and completion momentum no matter what curveballs are thrown at the industry.

#1 Reduce Connection Times

Making up a stand of drill pipe requires meticulous timing and execution by rig crews. Knowing where to improve starts with a clear view of connection times across the board. That’s where Corva’s Connection Times app comes into play. On bottom to slips, slips to slips, slips to on bottom, and weight to weight – this app enables crews to easily spot areas to improve and trim times.

Actual Client Results: $17,300 saved per well by cutting connection time by 2 minutes (208 connections, $60k daily rig cost)

#2 Minimize Swap Over Times

As we’ve seen on the drilling side, operational KPIs are something that should be tracked and constantly refined in order to drive performance higher and costs down for completions.  We should challenge our frac and wireline operators to reduce swap over times.  To do this, we need a way to track and compare performance across morning and night shifts, set goals, and trim down times.  Corva’s Swap Over Times app allows target goals to be set and automatically tracked.  It enables field and office personnel to visualize time spent transitioning between frac and wireline operations and stay on track with their goals.

Actual Client Results: $174k estimated savings by trimming swap overs by 25 minutes in two weeks (assuming daily burn rate of $100K and 100 stages)

#3 Increase Rotary ROP

Because drillers spend most of their time on rotary drilling, a boost to rotary ROP by even a few percentage points can significantly cut project cycle time and costs.  Attaining optimal ROP requires constant analysis of rig and offset well data, underscoring the need to process and visualize drilling parameters in real-time. Corva’s suite of apps delivers this real-time analysis with tools like ROP and MSE Heatmaps, which recommend optimal weight on bit and RPM parameters. And with our Driller’s Roadmap, drillers can harness offset well data to find the best practices and parameters that yielded best-in-class performance through each formation.

Actual Client Results: $30,000 saved per well by boosting ROP by 13% (12 hours of rig time saved, $60k daily rig cost)

#4 Optimize Frac Chemical Usage

How slick does your slick water frac really need to be?  That’s a million-dollar question indeed.  Costs add up for friction reducer (FR), crosslinked gel, and other fracturing fluids.  With Corva, however, you can dial-in just the right amount every time and book the savings.  Our Well Comparison app provides two levels of insight that guide stage-to-stage chemical volume selection: 1) users can mine offset wells to see what worked best through the same formations, and 2) up-to-date pressure response data is provided for the last stage of the target well, enabling completion staff to continuously adjust chemical treatment to balance friction pressure and cost.

Actual Client Results: $47,500 estimated savings on hybrid frac treatment on one well (assuming 2,000 pounds of crosslinked powder at $10 and a 50-stage completion pumping 50 gallons of FR per stage at $11)

#5 Decrease Slide %

Directional drilling intervals can reduce overall ROP by half and adds tortuosity to the wellbore, so it is critical to minimize sliding in order to reduce rig costs and wear on equipment. Corva has several powerful apps designed to minimize sliding and improve directional drilling accuracy, including our Toolface vs MD and Rotary Trend Analysis apps. Together, these tools enable directional drillers to monitor toolface consistency and slide effectiveness while reducing slide percentage and increasing rotary ROP.

Actual Client Results: $64,800 saved per well by reducing sliding by 13%/ (-1.08 days of rig time, $60k daily rig cost)

#6 Pick the Optimal BHA

Ensuring neutral tendency and minimizing dysfunction require careful analysis of historical BHA runs as well as selection and optimal configuration of downhole tools.  Corva’s BHA Optimization app helps engineers select the ideal BHA components, paired with the optimal WOB, RPM, and other drilling parameters. Leveraging hundreds of historical BHA runs and offset well data, this app enables drillers to pick the perfect BHA for the job and subsurface conditions. The result? The BHA selection process is cut from weeks to minutes. And by using the best-in-class string of tools every time, BHA runs are longer while boosting ROP and reducing slide %.

Actual Client Results: 72 hours saved per year for each Drilling Engineer

#7 Prevent Costly Wireline Mistakes

There’s nothing like stuck wireline guns and a fishing job to bring a completion to a standstill.  To keep your plug and perf operation running like clockwork your team needs up-to-the-second data, like CCL, line speed, line tension, measured depth, elapsed time, current, and voltage.  But this data is almost never available on the spot for real-time analysis, which can make the precise business of wireline work feel like a shot in the dark.  Corva users, however, now have real-time access with our app, which provides tools to verify plug placement and avoid costly mistakes like pre-setting or pumping off guns.

Actual Client Results: $1M estimated savings on fishing jobs and NPT by avoiding stuck, preset, and pumped off wireline guns (on a multi-well pad)

#8 Avoid Train Wrecks

Washouts, twist offs, fishing jobs, and other catastrophic events are the bane of drillers. In addition to the high cost associated with damaged equipment and remediation, these train wrecks have a cascading impact on drilling schedules, adding NPT and idle rigs to the cost. Corva helps drillers anticipate and avoid hazardous conditions with our Torque & Drag, Hydraulics Dashboard, and Predicted vs. Actual Divergence apps. Plus, drillers can monitor by exception using custom alerts that leverage state-of-the-art algorithms to provide early warning of washout pressure conditions or alert drillers when nearing formation top to prevent bit damage.

Actual Client Results: $200,000 estimated savings by preventing 3 surface and 6 downhole washouts (Over 2-month period and multiple wells)

Adding Up Drilling and Completion Savings

In the real-world examples above, we’re only taking into account the results of a few wells. Even so, the results are impressive with a combined savings of more than $1,500,000. But factor in continuous improvement over many wells and the cost savings accrue, potentially knocking a couple of million off the cost of a multi-well pad. And for factory drillers with hundreds of sites in their inventory, it’s a multi-million-dollar savings that can fuel a new wave of drilling regardless of the pricing environment.
