Austin Chalk Update: Challenge Accepted

The Austin Chalk formation is well known historically for being a challenging play. The play runs in a crescent shape from South Texas through East Texas and into Central Louisiana. It is a hybrid cross between conventional fractured...


Each basin presents its own unique drilling challenges. At Panther, we have the experience to manage them all. Learn more about how we do it.


Panther has experience in the most active basins in the U.S., including the Permian Basin, Austin Chalk, Eagle Ford, Haynesville and South Louisiana inland waters. Each basin presents unique drilling challenges, and we have the experience to manage them all.


The Haynesville play of North Louisiana, extending into East Texas, is characterized by deep wells with high bottomhole temperatures. These high temperatures can wreak havoc on drilling equipment and present challenges for mud systems. Additionally, the fractured and impact-resistant rocks that make up the formation can cause mud losses and affect ROP.

Common drilling challenges:

  • High downhole temperatures
  • Mud losses
  • Fractured formations
  • Long laterals
  • Frequent trips due to downhole tool failures
For success in the Haynesville basin, Panther recommends mud systems that allow operators to drill deeper in high-temperature environments using oil-based and synthetic muds. Maintaining rheological fluid properties in the lateral section is important to maintain lubricity and reduce torque and drag. Rheological properties ensure proper hole cleaning, including extreme thermal stability, resistance to H2S and CO2 contaminants and HP/HT lubricating capabilities. Panther also offers high-performance WBM systems as an environmentally acceptable alternative to OBM.

Haynesville utilizes both open pits and closed-loop systems for mud conditioning and disposal. There is a scarcity of trucking in the Haynesville region, so securing a reliable and fully vetted trucking company is critical for safe and efficient cuttings disposal.

(Note: Panther supplies only mud in this basin and does not perform haul-off and disposal.)

Permian Basin

The Midland and Delaware basins of West Texas and eastern New Mexico are the most active drilling areas in the U.S. The Permian Basin is no stranger to common drilling challenges, like mud losses, bit balling and unconsolidated sands and clays (locally referred to as redbed or gumbo) that result in fouled bits and BHAs. Drilling in New Mexico also requires special expertise, as state regulations require closed-loop drilling systems for every well.

Common drilling challenges:

  • Bit balling
  • Gumbo attacks directly attributable to drilling fluids
  • Mud losses
  • High rates of penetration
  • Sliding and rotating efficiency
  • Bit and BHA wear and damage
  • Proper hole cleaning
  • Torque and drag modeling
  • Strict regulatory controls by the State
For successful operations in the Permian Basin, Panther recommends fluid systems that minimize washouts and reduce dump and dilution rates in salt sections. Systems that help drill the intermediate and lateral sections can eliminate the salt casing string and offer an economical, time savings advantage.
Panther offers a full array of drilling fluids treatment and management services to operators in the Permian Basin. Both oil-based and synthetic systems, including a Brine/XC polymer/PAC system, provide viscosity and low filtration for hole cleaning, solids suspension and shale stability.

Austin Chalk

The Austin Chalk of Central Texas has developed a reputation for high temperatures and high mud losses. Wells drilled horizontally into the naturally-fractured chalk formation are always full of surprises. Cutting into an unexpected fracture can result in a kick if overpressured or losses if not. Onsite drilling fluids engineers must be on alert and ready to respond at a moment’s notice.  

Common drilling challenges:

  • High bottomhole temperatures
  • Mud losses due to natural fractures
  • Drilling kicks related to fractures
  • Drilling issues related to long laterals, including hole cleaning, torque and drag reduction, and maintaining high rates of penetration 
Panther recommends a system with consistent rheological properties even in a high-temperature environment. The system should reduce ECD, provide good hole-cleaning properties and high penetration rates, and incorporate a proper LCM program into the drilling fluid program. Our PFM LS-7 is an example of a proprietary LCM additive with high success in the Austin Chalk.
Successfully drilling Austin Chalk requires heavy mud. Panther recommends OBM for faster drilling speeds. For mud reconditioning and cuttings disposal, a typical solids-control setup is three shakers and two centrifuges. The landowner typically chooses an open pit over a closed-loop system. Trucking is an issue in the Austin Chalk since it is not as busy as other basins, and there are not as many trucking companies available. This makes it more critical to have trucks on standby once drilling commences.

Eagle Ford

At more than 400 miles long and 50 miles wide, the Eagle Ford play of South Texas presents wide-ranging drilling challenges depending on your location. Drilling targets may be as shallow as 4,000 ft in the northeast sections and as deep as 14,000 ft toward the southwest. This geographic expanse presents changing drilling conditions requiring different drilling fluids management approaches. 

Common drilling challenges:

  • High bottomhole temperatures
  • Mud losses
  • Frequent kicks
  • Tight shale
  • Differential sticking 
  • High trucking costs due to lack of nearby disposal sites
Panther recommends the operator select a drilling fluid that prevents shale instability on the surface and intermediate casing hole sections. These fluids must handle entirely different wellbore stability problems in the reservoir section, maximize lubricity and allow for good hole properties. Panther can provide an environmental alternative system such as high-performance water-based and synthetic-based systems.
In the Eagle Ford, drilling typically begins with a light 10 lb/gal mud weight and operators weight up as needed during drilling. OBM is the mud of choice in the Eagle Ford. Panther’s total fluid management helps streamline operations, bringing efficiencies not seen compared to using multiple vendors. Also, new blends and new chemistry have improved efficiency. Better equipment, such as new shaker technology, improves solids control performance. Faster drilling rates necessitate more open-top tanks on location to keep up with the cuttings volume produced by faster drilling.

South Louisiana

Characterized by wells drilled south of the I-10 boundary, the South Louisiana drilling region is home to wetlands, swamps and other low-elevation drilling locations accessible only by boat. The frequent need to use drilling barges presents logistical challenges for moving and maintaining equipment and drilling supplies.  


The downhole drilling environment presents challenges due to numerous salt structures that produce tectonic stresses and unconsolidated sands and clays (locally referred to as gumbo) that result in fouled bits and BHAs.  

Common drilling challenges:

  • Gumbo attacks
  • Mud losses in sand intervals
  • Tectonic stresses from nearby salt structures
  • Closed-loop systems for all barge work
  • Disposal by injection for all wells
  • Dock logistics
For successful operations in the South Louisiana inland waters, Panther recommends mud systems that prevent large surface washouts due to reactive clays and provide reduced dilution rates. The system must also offer chemical and mechanical shale inhibition to avoid swelling and must stand up to contaminants. Consideration of hole cleaning and possible high mud weights is important, as well as using environmentally-friendly synthetic-based muds and high-performance water-based muds as alternatives to diesel-based systems.
Since the inland waterways consist mostly of barge work, logistics are essential. Experience comes into play as streamlined logistics add to the operator’s bottom line. When working offshore, closed-loop systems are a must. Using mainly OBM on these wells, safely transporting OBM to the rig is critical. Since there is limited setup space on barges, there may not be room for a full solids control setup; therefore, maintaining consistent mud weight in the fluid system is vital. Pre-planning is critical since materials and chemicals cannot be delivered immediately. For example, the fluids company must have the correct amount of barite on the barge. Experience in these types of wells, especially for logistics, is key to a successful job.

Appalachian Basin

The Appalachian Basin covers large areas of Pennsylvania and West Virginia and parts of New York, Ohio, Maryland, Virginia and Kentucky. The basin includes two main shale plays: the Marcellus and the Utica. The Appalachian Basin holds significant deposits of dry natural gas. True vertical drilling depths range from 6,000 ft to 7,000 ft in the West Virginia and Pennsylvania areas of the Marcellus (which sits above the Utica) to 8,000 ft for areas of the Utica shale in Ohio.

The Utica Shale produces oil and gas, with the oil-bearing region mostly in central and eastern Ohio and northwest Pennsylvania and gas-bearing areas in eastern Ohio, northern West Virginia, west and north Pennsylvania and central and southern New York.

The Marcellus Shale produces mainly natural gas and includes the Devonian Shale-Middle total petroleum system, or TPS, and Upper Paleozoic TPS. It is estimated that 96% of resources reside within the Interior Marcellus assessment unit (AU), one of three AUs that make up the Marcellus; the other two are the Western Margin Marcellus AU and the Foldbelt Marcellus AU.

Common drilling challenges:

  • Strict environmental regulations
  • More stringent haul-off and disposal regulations
  • Competition for water resources (used for drilling mud) in highly populated areas
  • High downhole temperatures
  • Mud losses
  • Fractured formations
  • Long laterals
  • Frequent trips due to downhole tool failures
  • Environmentally acceptable base oils

For successful operations in the Appalachian Basin, Panther recommends mud systems that allow operators to drill deeper in high-temperature environments using oil-based and synthetic muds. 


Maintaining rheological fluid properties in the lateral section is important to maintain lubricity and reduce torque and drag. Rheological properties ensure proper hole cleaning, including extreme thermal stability, resistance to H2S and CO2 contaminants and HP/HT lubricating capabilities. Panther also offers high-performance WBM systems as an environmentally acceptable alternative to OBM.

This mountainous region presents topography challenges for haul-off and disposal as trucks sometimes navigate treacherous roadways in ice and snow. 

Challenges are mainly environmental, including access to large amounts of water for hydraulic fracturing and wastewater management. Since a large part of the basin is in or near large population areas, avoiding drilling through or near water tables that supply many major cities is challenging. During drilling, Panther has access to multiple environmentally friendly base oil suppliers to ensure product supply that helps avoid supply chain issues.
