Kriloha Ltd. supplies Bull Dog Spears, a more aggressive and heavy-duty version of standard wireline spears. They are specifically designed for retrieving larger diameter tubulars or heavy intervention tools that require maximum grip and pulling capacity. The bull dog spear incorporates reinforced slips with deeper bite profiles, giving it a much stronger hold on heavy or thick-walled tubulars. Built from high-strength forged steels, Kriloha bull dog spears are manufactured to API 6A and ISO standards, making them ideal for both standard and HPHT wells. Applications include fishing large wireline jars, downhole safety valves, heavy subs, or parted bottom-hole assemblies (BHAs). The bull dog spear is particularly valuable in emergency recovery situations where tool loss can cause extended downtime. Each Kriloha bull dog spear is subjected to maximum load testing, slip endurance trials, and corrosion resistance checks, ensuring rugged dependability in harsh environments. As a supplier and facilitator, Kriloha Ltd. provides various spear sizes, replacement slips, and operator training, making our bull dog spears the go-to option for operators facing high-risk, heavy-duty fishing operations.
