With commodity prices rising, so is the prospect of a surge in drilling activity. As companies scope and plan their prospective drill programs, there’s a lot of factors to consider as to where/what wells to drill. In this week’s post, we’ll focus on one of those factors: Drill Problems – Risk Avoidance and Mitigation.
Looking back at the last three years of drilling in Alberta, we ran some numbers using XI’s proprietary Drilling Database and various data-mining techniques to get a sense of where drill problems are most prevalent.
What is considered a “drill problem” you ask? Good question…for this article, we’re considering all AER reported Blows/Blowouts, Kicks, Circulation Losses, and Water Flows. Also included are incidents of Stuck Pipe, Fishing, and Circulation Losses.
We can see from the figures above that Grande Prairie is not only the second most active region in the province, but where operators are most prone to experiencing drill problems, most of which being circulation losses.
Let’s take a closer look…
It’s one thing to be aware of historical drill problems, it’s a whole other ballgame to understand the impact of those problems. A circulation loss on a well could amount to ½ day of NPT (non-productive time), or it could amount to 3+ days of downtime and mitigation procedures.
XI identified 115 Montney wells drilled in and around Grande Prairie that experienced drill problems. In the drill curves shown below, you can see the significant impact these issues had on their overall drill times.
Those 115 wells represent a broad spectrum of wells across a wide variety of depths.
Let’s narrow in a bit further…
So, what next?
For some this may be all the information they need, depending on the question being asked/decisions to be made). For others, this simply opens yet another door and raises new questions. To follow the rabbit further down the hole, it’s a matter of reading into these wells.
Unless these are their own drills, an operator would have to hunt down the drill records for each well they want to investigate:
Regardless of how one gets their data, historical knowledge is critical to successful drilling in any area. Being aware of previous drilling complications helps you prepare and strategize how to best deal with them.
