CO2 Contamination Nov 06, 2019

Show notes

Bicarbonates? CO2? What’s the contaminant and how would you know? Does lime fix everything? We’ll take you through the signs on a mud check and a bit of the chemistry.

Lost Circulation - Episode 28 Oct 30, 2019

Show notes

Lost circulation creates all kinds of drilling challenges. Treatment can sometimes feel like more of an art than a science. We’ll discuss different loss scenarios and some ideas of how to stop them.

Corrosion - Episode 27 Oct 23, 2019

Show notes

With every drilling rig comes a whole lot of rust. Why does metal corrode and what can happen if downhole equipment corrodes? What can we do with drilling fluids to minimize corrosion rates?

Sweeps - Episode 26 Oct 16, 2019

Show notes

In this episode, Matt and Justin discuss the application of drilling fluid sweeps and their respective functions as they relate to enhancing wellbore conditions. Drilling fluid sweeps are typically pumped to help clean the wellbore of cuttings that have not been removed with normal fluid circulation or to apply lost circulation material to the wellbore when lost circulation occurs.

Oil Based Mud Components - Episode 25 Oct 09, 2019

Show notes

The listeners have questions and we have answers. In this episode we answer the question of, “What are the key components of oil based mud and what are their functions?”

In this episode, we break down each product of what makes up an oil based mud and describe their functions and importance of each.

Ballooning – Episode 24 Oct 02, 2019

Show notes

Wellbore ballooning or “breathing” is a topic often discussed but not properly understood. Ballooning or breathing is when fluid is forced into the rock’s micro fractures while pumping which are open only enough to contain fluid but not enough to permanently fracture the rock. When we stop pumping and reduce the hydrostatic or equivalent circulating density, the overburden of the rock forces the fluid back into the wellbore.

Brines - Episode 23 Sep 23, 2019

Show notes

Brine based drilling fluids are a widely utilized system for drilling and completions due to their ability to protect the formation. These fluids are formulated with a brine as the liquid phase and selected bridging solids and polymers. Listen to this week’s episode while we dive into the world of brines and their use in drilling and completions.

Wellbore Instability – Episode 22 Sep 18, 2019

Show notes

In this episode Matt and Justin discuss the topic of wellbore instability. As the name implies, wellbore instability refers to wellbore that has the tendency to cave or collapse due to unconsolidated formations, fractured formations and chemically/mechanically stressed shale. Drilling fluids have a key role in preventing such phenomenon.

Drill-In Fluids - Episode 21 Sep 10, 2019

Show notes

Reservoir drill in fluids are fairly special systems used to minimize formation damage. Matt and Justin review when a reservoir drill-in fluid is used, how they are designed, and how they are run in the field.

Wellbore Strengthening - Episode 20 Sep 04, 2019

Show notes

In this episode we discuss the true meaning of wellbore strengthening and how we can use this type of program to help increase a well’s fracture gradient. We also go through proper planning and lab testing to determine the right products and application for a given job.
