Toe prep is the set of operations that prepare the toe, or far end, of a horizontal well for fracturing. It typically includes pressure testing the casing, pumping acid, and opening the toe sleeve or initiating the first stage. Toe prep establishes a reliable injection point so the frac operation can begin cleanly. Tejas provides toe prep across the Permian Basin.

Frequently asked questions
Toe prep is important because the first stage sets the tone for the entire frac. A properly prepared toe confirms casing integrity, establishes a clean breakdown, and reduces the risk of delays once the frac crew mobilizes. Skipping or rushing toe prep often leads to stage-one problems that cost rig time to resolve.
Tejas toe prep includes casing pressure testing, pumping down acid, opening toe sleeves, and pumping down wireline guns, all while collecting real-time wellbore data. Tejas runs fit-for-purpose pump down units paired with acid transport and storage, so delivery, blending, and pumping are handled by one dedicated crew on location.
A toe sleeve is opened by applying pressure to shift the sleeve and establish the first injection point at the toe of the lateral, creating the path for the initial frac stage. Tejas uses fit-for-purpose pump down equipment to pressure up, open the sleeve, and confirm injectivity, while capturing the wellbore data that verifies the toe is ready for the frac.
Toe prep commonly uses hydrochloric acid to break down cement and establish injectivity at the toe. Tejas supplies and transports acid as part of the service and tailors the concentration and volume to the casing and formation. Handling acid delivery and pumping under one provider reduces coordination risk on location.
Toe prep on a typical horizontal well is usually completed within a single working window, with timing driven by depth, casing design, and the acid program. Because Tejas brings dedicated equipment and crews sized for the job, toe prep is executed without waiting on shared assets, which keeps the frac schedule on track.
Casing pressure testing applies pressure to the casing to confirm its integrity and identify leaks before the frac begins. During toe prep, it verifies the well can hold the pressures the frac will impose. Tejas performs this testing and captures the data, which can also support wellbore data submitted to the Texas Railroad Commission.
Yes. Tejas captures real-time wellbore data throughout the toe prep process, including pressures during testing and acid placement. That data verifies casing integrity, documents the breakdown, and gives the operator an early read on the well before the full frac begins, which supports better decisions on the rest of the completion.
Tejas uses an advanced fleet of fit-for-purpose pump down units and acid transports built specifically to pressure test, pump down acid, open toe sleeves, and pump down wireline guns. Acid transport and storage capability means delivery, storage, and pumping are handled together, and real-time data acquisition runs throughout the operation.
Tejas provides toe prep services from its Midland, Texas base across the Permian Basin and into surrounding plays including the Eagle Ford and Haynesville, with operations reaching Texas, New Mexico, Oklahoma, and Louisiana. Equipment is staged regionally to keep mobilization fast for West Texas operators.
