Oxford Well Engineering, London

Oxford Well Engineering is a London consultancy. We design wells, plan them and stay with them while they are drilled, working beside your own drilling team.

What we do

We can come in at any stage of a well.

  • Well engineering and drilling designWell designs, casing and tubular design, and the drilling programme.
  • Directional well planningTrajectories, anti-collision and relief well planning.
  • Drilling project managementCampaign planning, tenders, operations and the end of well report.
  • Real-time drilling optimisationEngineers reading the rig data with you while the well is drilled.
  • Integrated well data analysisWhat happened downhole and why, rebuilt from the data.
  • Plugging and abandonmentDesigned, executed and recorded, barrier by barrier.
  • Geothermal well engineeringWell designs for geothermal wells and their temperatures.
  • Carbon capture and storageWell engineering for storing carbon dioxide underground.
  • Technical due diligence on wellsAn independent view of wells and drilling risk before a deal.
  • Specialist wells coursesHands-on courses in wells and drilling, taught on the software.

Our latest development

You sign in from a browser. It costs a well before it is drilled and reads it while it is drilled. Its modules follow, one at a time. The real-time part runs in a desktop edition, which keeps rig data on your own machine.

WellCost OptimaStart a well

The problem
Building a well cost by hand takes days.
What it does
Photograph the casing table and check what was read. Say where the rig works, pick a completion template and adjust any number you want. On the web, Android and iOS.
WellCost Optima, the AI import dialog with Photo to calculation
Photo to calculation: photograph a casing table or a well schematic.
WellCost OptimaPhoto to calculation
  • Hole size
  • Casing size
  • Shoe depth
  • Units
You check each value before it is used.

Sizes, depths and units are read off the photo. You check each one before it is used.

WellCost OptimaThe projection

The problem
One figure does not show the range, and changes after approval are hard to trace.
What it does
Time against depth and cost by phase. A P10, P50 and P90 range from offset wells. Lock the AFE and every later change is logged against it.

RT-DOX

The problem
A plan only helps if you can see the well against it while there is still time to act.
What it does
The recorded drilling over the plan, section by section. Its Dynamic Performance Gap is a moving measure of performance in real time: hours won or lost while the pipe is moving.
See RT-DOX
RT-DOX, a hole section with the actual depth trace over the plan
One hole section: the well as drilled over the plan.

Dynamic Performance Gap: hours won or lost while the pipe is moving, as a running total.

TopWise

The problem
The prognosis says where the next formation top should be. The rock does not always agree.
What it does
TopWise predicts the next top ahead of the bit with a range, and corrects it as the well is drilled and matched against the offset wells.
See TopWise
TopWise, the correlation console with the look-ahead to the next formation top
The correlation console: the next top, how far ahead it is, and its range.

Real-Time NPT & ILT Intelligence

The problem
Small losses never reach the daily report. Each one is small, and fast drilling hides them.
What it does
Flat time, slow tripping and drilling speed against plan are found section by section from the time stamps, and priced.
See NPT & ILT
RT-DOX, the Invisible Lost Time card with flat time, slow tripping and rate of penetration against plan
Invisible Lost Time: the time lost and not reported, by kind and by section.

ToolMD

The problem
After a run, someone has to decide whether a tool runs again or goes to the shop, and how deep the work goes.
What it does
ToolMD reads how a mud motor or an MWD tool was run and gives one maintenance level for the tool, with the evidence behind it.
See ToolMD
ToolMDMaintenance level

Minor shop maintenance

  • Replace bearing pads
  • Greasing
  • Replace external seals
  • General redressing

Change or repair parts

  • Replace or service the power section and rotor

Digital Drilling Optimization, RTOC

The problem
Drilling data sits in many plots and logs. Remote support needs them in one place.
What it does
RTOC brings the dashboards, depth roadmaps and time logs together in one place.

How it works

A short film of WellOptima AI at work. No sound needed.

  1. Photograph the casing table.
  2. Check what was read.
  3. Say where the rig works.
  4. Adjust any number you want.
  5. There is the projection.
  6. And the range.
  7. Lock the approved AFE.
  8. The well as drilled, laid over the plan.
  9. A moving measure of performance, in real time.
  10. The lost time nobody reported.
  11. The next formation top, ahead of the bit.
  12. Every dashboard in one place.
  13. A maintenance level for each tool.
