“…Based on the foregoing, The prime differences between overbalanced drilling (OBD) and underbalanced drilling (UBD) are which the drilling fluid in UBD does not implement as a barrier against the pore pressure, so which it allow formation fluids influx into wellbore. Figure (1) illustrates the underbalanced drilling operating area, that is above the collapse pressure and below the formation pressure. Also, there are several differences which evolve from previous two main differences.…”

“…The results and analysis of the second hole of the well from (679m to 1887m) without SBP at 850 gpm and 8.8 ppg are illustrated in Table (1) and Figure ( 4) 1) that the pressure gradient is (0.461 psi/ft), noting that the highest pressure gradient for this section is (0.465 psi/ft) and the rate of cleaning for the well (CTR) is greater than (0.5), ranging between (0.55-0.63). In case 39, CTR begins to increase from (0.55) to reach (0.63) at the total depth in the Hartha formation, and this is due to the fact that ECD has become less than the pore pressure at this point, which is the beginning of Hartha formation.…”

“…Where, some formations may contain caverns, large or some problems, so losses are not totally controllable and additional measures must be taken to maintain the safety and efficiency of the drilling process. Lost circulation can be defined as a decrease or complete absence of the fluid flow to the formation-casing or to casing-tubing section [1]. MPD is a new technology which used to treat mud losses by controlling the annular frictional pressure losses during drilling operation, and this technique uses tools almost similar to the tools used in drilling underbalanced operation.…”

Many drilling problems are encountered continuously while drilling oil wells in the southern Iraqi oil fields. Many of these problems are ineffectively handled resulting in a longer non-productive time. This study aims to identify the formations such as Dammam, and Hartha formations،diagnose potential problems and provide the solution for lost circulation problem. After conducting a comprehensive study on the subject and based on available data, previous studies and some information, the managed pressure drilling (MPD) method was the best technique to solve this problem. This process may use various techniques including control of back pressures .Thus, reducing the risk and control the costs of drilled wells, which have narrow pressure window by managing the wellbore pressure profile. The well plan software program provided by Halliburton Company was used, this software is based on a database and data structure common to many of Landmark’s drilling applications. Mud used with various injection rates to choose the rate that provides the conditions to achieve the best drilling process, as it using mud weights of (8.8 -8.7 ) ppg and applied a surface back pressure (50 psi). Depending on specifications of second hole the optimal injection rate was chosen using the (hydraulics) program. As a results, rate of water injection (850) gpm, is the best which it provides a good efficient cutting transport ratio (CTR), which means high stability and preventing formation damage in addition to controlling in mud losses

“…Furthermore, the following functions are performed by drilling fluid [1] Drilling mud losses and issues related to lost circulation during drilling the thief zones account for a considerable cost in the oil and gas industry. Millions of dollars are spent annually to stop and minimize this obstacle [2]. Lost circulation can be defined as "the partial or total loss of circulating fluid from the wellbore to the formation.…”

“…Drilling fluid is very important in the drilling operation. If the drilling fluid was not designed properly, many unwanted consequences can happen such as lost circulation and stuck pipe issues (Alkinani et al 2019;Al-Hameedi et al 2018). To obtain the desired properties, chemical and non-biodegradable materials have been the traditional additives that are used in drilling fluids.…”

Serious problems will be presented due to using conventional chemical additives to regulate the drilling mud properties, as they have health, safety, and environmental side effects. Thus, there is a considerable necessity for alternative multifunctional bio-enhancer drilling mud additives, which can assist in optimizing the drilling fluid specifications and enhance its effectiveness with the least effects on the environment and the drilling personnel safety. The effects of adding two concentrations of palm tree leaves powder (PTLP) to water-based mud were conducted under fresh and aged conditions using standard API drilling fluids testing methods such as rheometer/viscometer, pH meter and temperature, and filter press. All tests results were minutely recorded to understand the influence of PTLP additives on the drilling mud properties. The results indicated that PTLP as an effective material to be used as pH reducer, viscosity reducer, and as an excellent filtration loss control agent under the surface and sub-surface conditions. Thus, PTLP has excellent feasibility to be utilized as biodegradable drilling mud additive replacing or at least supporting other conventional chemical additives, which have usually been used for the same purposes such as lignosulphonate, chrome-lignite, and Resinex. Finally, this work can serve as a practical guide for minimizing the cost of the drilling fluid and reducing the amount of non-biodegradable waste disposed to the environment.
