2017年8月30日 · Knowing the difference between a barrel of oil (BBL) and a barrel of oil equivalent (BOE) can be very important when looking at the reserves and production potential of a field. Imagine two identical exploration projects with exactly the same proven reserves of BOE…

2009年5月9日 · There are several formulas to calculate inner capacity depending on unit of inner capacity required. The formula are listed below; Oilfield Unit Calculate Internal Capacity Factor in bbl/ft Inner Capacity in bbl/ft = (ID)2 ÷1029.4 Where; Internal Diameter (ID) in inch Example: Determine Internal Capacity Factor in bbl/ft of a 6-1/8 in. hole:

2009年5月15日 · Learn to calculate amount of cuttings produced per foot of hole drilled and solid generated in total depth drilled

2015年9月28日 · Dispersion of clay-bearing drilled solids creates highly charged colloidal particles (<2 μm) that generate significant viscosity, particularly at low shear rates, which aids in suspension of all solids.

One estimate or rule of thumb of the amount of mud loss attributed to this effect is 1 bbl of mud per bbl of cuttings drilled. So, as in the previous example, where 8.5” hole is drilled at a sustained rate of 50 feet per hour, an additional 3.5 bbl of mud would be lost on the drill cuttings in the period of one hour or 50’ of hole.

2014年3月30日 · Figure 1 – Cutting Generated While Drilling. The following formula is used to calculate cutting volume generated while drilling; Where; Vc is volume of cutting in bbl/hr. Ø is formation porosity (%). D is wellbore diameter in inch. ROP is rate of penetration in feet per hour. Vc can be presented in several unit as follows;

2017年1月3日 · The drilling-fluid system has increased to 1100 bbl because new hole of 100 bbl was drilled. The volume of the rock represented by the new hole is virtually the same whether it is ground into cuttings or is solid rock.

2017年1月11日 · The dilution factor (DF) is the ratio of the volume of new mud actually prepared to that which would have been required with no drilled-solids removal. In this instance, a volume of 759 bbl of new mud has been built and the DF is 759 bbl / 1946 bbl, or 0.39. The required dilution was 39% of what it would have been if none of the drilled solids ...

bbl An abbreviation for oilfield volume unit of barrel, a volume of 42 US gallons (1 bbl = 0.159 m ³).
