High-Performance PDC Bit Delivers Exceptional Results in Shiqianfeng Formation: Well Su 75-48-20X Case Study
Overview
Shaanxi Hainaisen Petroleum Technology Co., Ltd. (Hainaisen) is a leading manufacturer of premium PDC drill bits for the oil and gas industry. In this case study, we showcase how our custom-engineered 8-1/2" SD9633 PDC Bit solved critical drilling challenges in the highly abrasive Shiqianfeng Formation, delivering industry-leading penetration rates and cost savings for our client, Drilling Team 50503, on Well Su 75-48-20X.
Challenge
Well Su 75-48-20X, a critical development well in the Sulige Gas Field, required drilling a 979-2970m section through the Shiqianfeng Formation, known for its extreme hardness and high abrasiveness. The client's existing bit solutions were underperforming, with slow ROP, limited footage, and excessive tripping time, which threatened to delay the project and inflate operational costs. The team needed a bit that could:
- Achieve maximum footage in a single run
- Deliver significantly higher mechanical ROP
- Reduce non-productive time and overall drilling costs
Hainaisen's Custom Solution
Our engineering team conducted a comprehensive analysis of the well's lithology, drilling parameters, and operational goals. We selected and customized our SD9633 series PDC bit, specifically designed for hard and abrasive formations:
- Premium PDC Cutters: High-impact, wear-resistant cutters for extended durability in abrasive rock
- Optimized Blade & Hydraulic Design: Enhanced cuttings evacuation and cooling to maintain consistent performance
- Robust Bit Body: Engineered for stability and reduced vibration in challenging formations
Field Results
The 8-1/2" SD9633 PDC Bit (Serial No. A3278) was run in the 979-2970m well section of Well Su 75-48-20X, with the following outstanding results:
✅ Total Footage Drilled: 1991m in a single run
✅ Net Drilling Time: 88 hours
✅ Average Mechanical ROP: 22.62 m/h
✅ Cost Savings: Reduced tripping operations by 30% compared to offset wells, cutting overall well section costs by 25%
Client Testimonial
"The Shiqianfeng Formation has always been a bottleneck for our drilling operations. Hainaisen's SD9633 bit completely changed the game. We achieved nearly 2000 meters of footage in one run, with an ROP that was 40% higher than our best offset well. The bit's performance was flawless, and it helped us finish the section well ahead of schedule. Hainaisen's technical support and product quality are top-tier, and they are now our go-to supplier for PDC bits in this region."— Project Manager, Drilling Team 50503
