HXR Drilling Services - Extended Reach Drilling’s Post

Last week, we spent some time discussing how MW affects ROP, with the consensus being that it has a negative effect. How much of a negative effect, however, varied greatly, with a 1 ppg change yielding decreases in the 300% - 500% range in some studies, with others seeing a small to ~30% decrease. This week, we'll look at an actual well, monitored on-site by HXR ERD Specialists, that had two MW increases in the same section, the first .5 ppg, the second .6 ppg, and see if MW was the overriding factor, or if some other things may have been going on.

This week, let's take a look at ways to reduce ECD at the Bit/BHA by bypassing some of the flow to the base of the DP. This is done every time we UR a section, but the bypass area (UR tfa) isn't always given enough attention, leaving some of the potential benefits on the table. Similarly, there are benefits to bypassing some of the fluid in non-UR holes as well; particularly in slimhole applications. Give it some thought.

In this Training Module, let's look at the effect Surge Pressure and ECD has on running a liner; not on the formation, but on the hookload itself. Most members of the drill team can picture how running very tight-clearance pipe into the hole can cause high surge/circulating pressures; what is less understood is how the equal and opposite force can "push back" on the drillstring. This "hold-up force" can be substantial. Give it some thought; it may be crucial to the success of your next project.

We've been talking about Managed Pressure Drilling in the last few modules, but that leaves the question, "How do I get pipe down? What might that scenario look like?" So, this week we'll take a look at Managed Pressure Casing operations using the same well we've been discussing and compare it with a Conventional run. We'll also take a brief look at an example Floated Managed Pressure Casing run. Will it match YOUR well? Probably not (unless you're drilling in the area this well is based on...), but hopefully it gives you ideas for some of the more difficult wells on your schedule. Give it some thought.

In Part II of the Surge/ECD Effect on Hookload series, we'll look at the use of a fluid bypass tool and how it they can increase running speed while reducing surge on the formation.

To wrap up our discussion about shallow, narrow pressure margin ERD wells, let's take a look at one possible liner-running scenario, and see if a design change in the 8.5" section would help with getting pipe down successfully. Maybe you're facing a similar issue?

With many Operators looking to significantly increase the length of their laterals, possibly for the first time, it is probably a good time to revisit what the planning for some of these wells would look like. In this week's Training Module, we'll take a look at what it might take to float 5.5" liner out past 33,000'. Hopefully it is helpful - something to consider anyway...

As we have discussed in the past, it is pretty common to use low-angle Exploration or even older, short-stepout ERD well designs as the basis for upcoming Complex or longer ERD wells. The problem is that doesn't always work out; usually from a Hole Cleaning, SPP or ECD standpoint. Once you realize that, then sometimes there is still the tendency to go down the path of "half-size" casing and underreaming virtually every hole size below Surface pipe; that is a rabbit hole you should really try to avoid if at all possible... But, like anything else, sometimes it can't be helped. In this module, let's take a look at the difference in flowrates needed to clean various hole sizes, using a 150-200 fpm AV range as the design criteria (we'll assume you can get the RPM required - that is not always a given...). Then we'll discuss ways to mitigate some of the issues that come up. The exact scenario likely won't match your well, but it is guaranteed that the variable effect seen will translate.
