“…It underlines the drilling benefits and their operational success. To reduce the negative impact of cost, formate systems can be recovered at the end of each job and recycled [21]. Despite many advantages, formate muds are challenged because they might affect standard nuclear logging tools [22].…”

The worldwide growing demand for energy drives oil and gas companies to drill deeper and hotter wells. The exploration and the development of Deeply Buried Reservoirs (DBR) generate major technical challenges due to the extremely high pressures and temperatures met (1 400 bar, 300°C). Currently, several drilling fluids are emerging. They are briefly reviewed at the beginning of the paper. The technical difficulty related to HP-HT mud is so significant that standard mud formulation technologies are irrelevant and alternative systems have to be considered. New formulations based on perfluorochemicals have been jointly developed by IFP Energies nouvelles (IFPEN), Solvay Specialty Polymers Italy and Total. Their lab characterizations are presented and reveal their promising benefits.

“…A decrease in viscosity results in several problems such as a reduction of the cutting lifting ability of the water-base muds. The poor thermal stability can be treated by adding formate based salts such as potassium and sodium formats in the polymer-based aqueous fluids [14] [15] [16]. Other less expensive means are also available.…”

The ever-increasing targets of drilling depth and reach, coupled with locational disadvantages have driven the oilfield drilling operations into new technology frontiers. Drilling fluids being an essential component of any successful drilling operation, adequate understanding of the impact of drilling fluid characteristics can eliminate a range of difficulties encountered during drilling operations and reduce drilling cost significantly.This article presents a comprehensive review of various types of drilling fluid systems and technology advancements and also the significant challenges faced by a drilling fluid engineer, starting with the basics and ending with extreme reservoir Conditions, with special emphasis on non-damaging drilling fluids. This paper is specially written for fresh petroleum engineering graduates and entry level drilling fluid engineers and drilling engineers as well as for drilling fluid research groups who would find many important information for a given drilling and reservoir challenge.

“…It underlines the drilling benefits and their operational success. To reduce the negative impact of cost, formate systems can be recovered at the end of each job and recycled [17]. Formate also has the advantage that much of the weight is provided by the base brine resulting in lower solids content [18].…”

A formate-based fluid has been successfully used in many HPHT well operations since they introduced in field practice. They have many advantages when compared with conventional HPHT drilling fluids such as: minimal formation damage, maintenance of additive properties at high temperatures, reduced hydraulic flow resistance, low potential for differential sticking, etc. Formate-based fluids can be applied during deep slim hole drilling, shale drilling, and reservoir drilling, salt and gas hydrate formations drilling. The laboratory research was carried out to determine composition of formate base drilling fluid. It was formulated using sodium and potassiumformate salts, KCL, starch and lime stone. Formate base mud is solid free system. So, mud cake is thin and resilient, it is conductive to improve cementing quality greatly. In these experiments, formate based drilling fluids containing two types of formate salt (NaF and KF) at different concentrations were tested by a Fan-50 viscometer. Experiments show that the formate drilling system has good rheological property and strong inhibition ability. It shows that potassium formate improves the thermal stability of polymers. Formate based drilling fluid achieve sufficient mud weight around 77 pcf was selected for field trial in one of the exploratory wells. Formate based brineis a free-solid Water Base Mud (WBM) which maintains rheological stability at high temperature and minimizes drilling problems. This case study shows how Formate based mud enhanced the wellbore stability and reduced the testing time and cost. Based on the success fulfield test results, it is planned to drill other deep formation with Formate based fluids in future.
