ViChem LPR-50Oil-Based Mud Performance Enhancer

Cost Effective Performance Enhancer • BiodegradableViChem LPR-50ViChem LPR-50 is an ester-based additive that significantly improves rate of penetration (ROP), reduces pump pressures, and increases electrical stability for oil-based mud (OBM) operations, while providing a cost-effective solution for achieving higher lubricity. High-performance and low toxicity ratings make it ideally suited to drilling in environmentally sensitive areas.

Specially formulated for Emulsion-based mud systems (EBM), ViChem LPR-50 offers multiple advantages over other lubricants, including easy mixing, a stable viscosity index, improved rheology and filtration rates, and enhanced lubricity.

ViChem LPR-50 outperforms other additives in thermal, oxidative, and hydrolytic stability.

ViChem LPR-50’s proven ability to increase ROP not only helps drillers save tens-of-thousands-of-dollars daily in rig-related costs, but also reduces the need for OBM support products. In this example, rigs using ViChem LPR-50 achieved significant cost savings through faster ROP and a significant reduction in emulsifier use.

Field and laboratory data were collected during three field trials of ViChem LPR-50. Fifty bbl sweeps were run containing 3.0% by volume ViChem LPR-50. Data were collected before and after treatment. Slugging pit samples were collected before and after addition of LPR-50.

Overall, the use of ViChem LPR-50 resulted in increased ROP, stable rheology, and lower mud costs.

The rheology-stabilizing effects of ViChem LPR-50 also reduced the volume of support products needed to control elevated HTHP filtrate typically associated with higher temperatures as OBM ages.

“ We first introduced LPR-50 in the Haynesville Shale. Running it in 50 bbl sweeps at 3% by volume, we saw an immediate reduction in torque and a significant improvement in ROP. Over time, we saw a 2-3 point reduction in yield point and gels, a 20% drop in HTHP filtrate, and a 50-100 volt increase in electrical stability. Emulsifier/wetting agent usage dropped 25% as well. The idea of adding lubricants to oil-based mud is still new so we always emphasize the upside of conditioning the mud. Directional drillers just love it.”
